10 Key Strategies for Preventing Errors in PHP Programming

When you're a beginner in learning the PHP programming language, you can get a little familiar with the errors and all the complications that often repeat themselves in projects. What is allowed for you as a beginner and what you can do while learning the basics of the PHP programming language is unimaginable in a serious PHP project. For that reason, it is necessary to take this PHP tutorial lesson very seriously. We apologize in advance if you don't immediately understand some parts of the code, because we haven't learned functions yet, for example, or how to write some text in a text file using PHP coding, which we will learn in the next tutorial lessons.

However, we hope that you will start getting used to seeing unfamiliar code in programming because it is often a practice. In real projects, you won't understand most of the things in the project even with significant documentation, but over time you will start to understand how some code works, even if you've never learned that part of the code before. You might even be excited to learn and see something new that you didn't know before, or how a colleague solved some things with their personal programming thinking from the real world. So, start getting used to it. This PHP tutorial lesson will definitely give you new insights into how to code in PHP, thinking ahead about the errors that must not exist in the final version and that no user of your project should ever see.

PHP is a powerful language for developing web applications, but like any programming language, it comes with challenges and risks of errors. Effective programming involves not only writing functional code but also minimizing potential problems. Before writing the first line of code, it's important to understand business requirements, identify potential issues, and plan the application architecture. A clear structure and upfront system design reduce the likelihood of errors due to a lack of organization.

Working with different versions of PHP can lead to incompatibilities. Always use the latest stable version of PHP that is compatible with your project. The latest versions come with security patches, performance optimizations, and the removal of deprecated functions, reducing the risk of errors. Never ignore errors. Use PHP's built-in functionalities such as try-catch blocks to catch exceptions and implement an error logging system. This practice allows for quick identification and resolution of problems before they become critical.

One of the main causes of problems in PHP applications is invalid or malicious user input. Validate all data entered by users to prevent SQL injections, XSS attacks, and other security risks. Good documentation makes it easier to understand how code works, both for you and your team. Document functions, classes, and key parts of the logic. Clearly written comments and guides help reduce misunderstandings and errors.

Preventing errors in PHP programming requires careful planning, discipline, and the application of best practices. By combining these strategies, you can significantly improve the quality of your code and reduce the likelihood of encountering serious problems in production. Quality programming is not just a goal but also a continuous process of learning and improvement.

The Perfect Guide, How to Install Windows 10 and Solve MBR Partition Table Issues?

At the beginning of 2019, our old PC reached the end of its life. It survived three monitors, two hard drives, three power supplies, and even had 2 GB of DDR2 memory added to its original 6 GB. We also upgraded its graphics card to a Gigabyte GeForce GTX 750 Ti 2GB. However, its aging AMD motherboard with a Pentium Dual Core CPU E5400 2.70 GHz had done its duty. We were quite attached to that PC since it had served us well for over 7 years.

After its demise, we couldn’t afford one of the top-of-the-line machines, so we settled for two lower-performance laptops. Instead of buying the most expensive high-performance computer, we opted for a budget-friendly machine that could handle at least 80% of our computing tasks. We aren’t including the latest games in that percentage. And we can tell you that we’re satisfied with what we managed to purchase.

  • Motherboard: AM4 A320, 2x DIMM DDR4 / SATA3 / GLAN / Audio 7.1 / USB 3.0
  • Processor: AMD Athlon X4 950, AM4 / 28nm / 4 physical, 4 logical cores / 2MB L2 cache / 65W power consumption
  • Processor Clock Speed: 3.5GHz (Turbo frequency 3.8GHz)
  • Cooler: AMD stock cooler
  • Memory: 8GB DDR4
  • SSD: 240GB SATA3 / 2.5
  • Hard Disk Capacity: 1TB SATA3 / 3.5 / 7200 RPM
  • Graphics Card: nVidia GeForce GT 1030 2GB / GDDR3 / HDMI / DVI-D / VGA / 64-bit
  • Sound Card: 7.1 System (integrated on the motherboard)
  • Case: Midi Tower Rhino RX459 / 500W power supply

Later, you can add an additional 8 GB of RAM to this machine and replace the graphics card with one that is twice as powerful, featuring 4 GB of memory.

When you buy a new machine, those are the happiest moments for any programmer. You usually think, “Now I’ll clear a spot for it and immediately turn it on, install Windows 10 Pro, and then enjoy installing other programs. I can’t wait to work with a 27-inch monitor.” However, that’s when the challenges begin, and you have to solve them on the fly. First, you might have trouble connecting the monitor to the computer. You’ll likely need an HDMI cable. At the time, we had an extension with an HDMI input, but the new computer required a different HDMI input.

So, you might find yourself returning to the computer store after purchasing the new computer to buy additional items you need. When we first turned on our new computer, we were pleasantly surprised. Instead of the old blue BIOS screen, we encountered a new UEFI interface, usually in a simpler brown color. We believe this depends on the motherboard you have. And then comes that initial moment when MS-DOS opens up, and we need to start installing the best Windows operating system of all time.

Windows 10, What Makes It the Best Operating System?

Despite the fact that the latest version of the Windows operating system, Windows 11, was released on October 5, 2021, Windows 10 remains the most popular Windows OS for desktop computers, with over a billion active devices still using it. Even with the newer, sleeker Windows 11, Microsoft continues to support Windows 10 through service updates until October 14, 2025. But why, after 8 years (Windows 10 was officially released on July 29, 2015), does Windows 10 still hold the reputation as the best Windows OS for desktops?

To answer this, we need to delve into the past. As you may know, every Windows operating system consists of a kernel that manages all processes in the computer, drivers that enable device functionality, configuration files (settings and preferences set by the user), a command processor that interprets commands into executable OS instructions, and a GUI - graphical user interface. Since the release of Windows 7 on October 22, 2009, each subsequent Windows OS (specifically the kernel) has been an evolution of the previous one. The differences lie primarily in the GUI, bundled software, and settings. Interestingly, this subtle variation determines the pricing of different Windows OS versions.

Before the release of Windows 10, Microsoft made a significant announcement: Windows 10 would work across all devices and be the final version of Windows. There would be no more new Windows OS versions; instead, Windows would evolve through upgrades, similar to how Linux distributions operate. Honestly, back in 2015, this saddened us as Windows users who always anticipated the next big release. Despite that, we also appreciate using Linux distributions.

The second piece of news that definitely had a significant impact on Windows users transitioning to the Windows 10 operating system was the marketing statement that Windows 10 would be free. However, we later realized that this offer only applied to those who had Windows 7, 8, or 8.1 installed. Despite many users expecting Windows 10 to work exclusively on 64-bit processor architecture, it turned out that you could install Windows 10 even on a 32-bit processor. From its release until December 2017, you could download a small program and upgrade your previous Windows OS to Windows 10 with just one click.

A few years before the release of Windows 10, we were fortunate. Thanks to substantial savings, we visited a computer store, purchased their most powerful machine, and requested additional upgrades. Back then, having such a PC in Serbia was rare. Even the technicians assembling the computer were a bit envious. We bought a licensed Windows Professional 7 Edition OS and didn’t regret spending that much money. During that time, Windows 8 and 8.1 were mainly seen in computer schools or pre-installed on newer laptops. However, they were definitely not as popular as Windows 7. Believe it or not, there are still people today who have an old computer with Windows 7 installed. So, we welcomed the summer of 2015 by transitioning from Windows Professional 7 Edition to Windows Professional 10 Edition.

Pokrenite svoje putovanje veb razvoja, uvod u Laravel radni okvir

Ukoliko učite PHP programski jezik, čiji tutorijal možete pogledati ovde; možete se pitati šta je to Laravel i zašto bi ste i to učili. Zar PHP programski jezik nije dovoljan da iskodirate kakav god hoćete veb sajt, pa ukoliko je neophodno ako zatreba možete ubaciti i JavaScript i Ajax. Pa, vidite ovako; Laravel je open-source framework; na Srpskom jeziku radni okvir; za PHP programski jezik. On vam pomaže tako što preuzima odgovornost umesto vas za veliki deo poslovne logike vaših aplikacija, za mnoge uobičajene komponente kao što su validacija unosa, pristup bazi podataka, autentifikacija korisnika, izrada šablona itd. Danas programeri koriste mnogobrojne radne okvire za razvoj aplikacija, veb sajtova, biblioteke i komponente koje su drugi programeri iskodirali i testirali da vi to ne morate isto kodirati. Radni okviri održavaju konzistentnost i fleksibilnost i dok vi razmišljate, gde i kako nešto iskodirati u PHP programskom jeziku u vašem projektu koji postaje sve veći i kompleksniji; radni okvir razmatra samo: "Koju komponentu treba da koristim ovde?" Ako se pitate zašto baš Laravel; onda je moj odgovor zato što je trenutno jedan od najboljih za PHP developere. Ako se vratimo u prošlost; jedan od prvih radnih okvira je bio 2004 godine Ruby on Rails. Brzo je postao popularan jer je takođe popularizovao MVC, konvenciju nad konfiguracijom i mnoge alatke koje su doprinosile programerima brz razvoj aplikacija. Zatim se pojavio CakePHP 2005 godine i onda se razvoj nastavio u vidu CodeIgniter, Simfony, Kohana, Zend Framework itd. Još, 2010 godine CodeIgniter je postao veoma popularan radni okvir za PHP programere ali je kasnije počeo da zaostaje u tehnološkom razvoju i postao je previše spor. Zato je u junu 2011 godine, Taylor Otwella ponudio svoj radni okvir; napredniju alternativu CodeIgniter-a koju danas zovemo Laravel 


( Laravel je trenutno jedan od najboljih radni okvira za PHP programere )

Laravel 1 je doneo autentifikaciju, lokalizaciju, modele, views, sesije i rutiranje. Sve je iskodirano od nule. Laravel 2 je bio zaslužan za kontrolore, IoC i Blade. Laravel 3 je doneo Artisan i Bundles. Laravel 4 je otišao još dalje sa distribucijom paketa preko Composer radnog okvira. Zato se i kaže da je Laravel baziran na PHP programskom jeziku ali i na drugom radnom okviru Composer-u. Laravel 4 je još 2013 godine doneo još mnogo divnih stvari koje PHP programerima olakšavaju posao poput database seeding, automatsko upravljanje sa konekcijama baza podataka, 2014-te upravljanje PHP Cloud serverima, Vargrant okruženje, upravljanje pretplatama itd. Laravel 5 je još 2015 godine doneo novu strukturu direktorijuma i keširanje ruta itd. Od prekjuče; tačnije 16 februara 2023 godine; Laravel je izbacio 10.2 stabilnu verziju koji zahteva minimum PHP 8.1 verziju. Svake godine se u prvih 6 meseci u SAD-u održava konferencija Laracon dok se ista održava u Evropi; tačnije Amsterdam-u u drugoj polovini godine; gde možete uvek saznati skoro sve o razvoju Laravel radnog okvira. E sad se možete pitati, ako je Laravel toliko dobar radni okvir zašto ga svi ne koriste? Mislim da postoje više razloga. Promene se često dešavaju u različitim verzijama, komponentama, kodu i postoje neke knjige i odlična dokumentacija o Laravel-u ali ponekad je komplikovano sve to uklopiti i ispratiti. Ukoliko koristite Share Hosting kod nekog provajdera; možda on jednostavno neće raditi. Druga stvar je ako vi zakupite vaš server. Tad možete da kontrolišete i da instalirate svašta na vaš hosting. Možete kompletan projekat da održavate i menjate kad se nešto promeni. Ali to zahteva mnogo više učenja i strašno je kad nad nekom komponentom nemate kontrolu. Zbog toga neki stariji iskusniji PHP programeri se drže čistog PHP  programskog jezika bez bilo čega što to može narušiti. Sve u svemu, što se mene tiče u svemu trebate biti fleksibilni; potrebno vam je vreme i mnoge greške da bi ste bili iskusniji u PHP  kodiranju ali jednostavno nema odustajanja. Uvek napredujete i učite. Još pre par meseci nije bilo šanse da instaliram Laravel na noviju verziju Linux distribucije Ubuntu-a zbog grešaka koje nisam razumeo dok je to danas druga priča.

Kako da instaliram Laravel?
