12 Top PHP Tips to Improve Your Programming Skills

12 Top PHP Tips to Improve Your Programming Skills

You likely have a quick thought already, but if you don’t, PHP is a standout amongst the most prominent and widely used programming languages for the online environment today. PHP stands for PHP: Hypertext Preprocessor and is clean and easy to use which were developed with built-in web development skills.

PHP was initially intended for use in website improvement but quickly developed to become a considerably more robust language. PHP’s primary role is as an “embedded” scripting language, which implies that the actual PHP code is embedded in HTML code. At the point when utilized like this, empowers your web server to process pages before they’re shown in the user’s web browser.

12 Top Tips to Write Fresh, Maintainable, and Reusable PHP Code

1. Cache PHP Scripts

The PHP programmers must recall that the script execution time varies starting with one web server then onto the next. For example, Apache web server serves an HTML page considerably quicker than PHP scripts. Likewise, it requires to recompile the PHP script each time the page is asked for. The programmers can rapidly eliminate the script recompilation process by generally caching scripts. They additionally have the alternative to lessen the script accumulation time significantly by using an assortment of PHP caching tools. For instance, programmers can utilize Memcache to cache many scripts, alongside lessening database communications.

2. Exploit Native Functions

While writing PHP code, the programmers have the alternative to achieve a similar target by using either native functions or custom functions. But the developers must exploit the implicit functions given by PHP to accomplish a kind of assignments without writing extra code or custom functions. The native functions will additionally assist the developers with keeping the application code fresh and straightforward. They can rapidly accumulate information about the native functions and their use by referring to the PHP user manual.

3. Keep the Code Legible and Maintainable

Usually, programmers get it daunting to read and modify the code composed by others. Subsequently, they require more time to keep and update the PHP applications productively. While writing PHP code, the programmers can without much of a stretch make the application simple to maintain and update by describing the use and importance of individual code snippets surely. They can make the code simple by adding comments to each code snippet. The comments will make it less demanding for other developers to make changes to the existing code later on without putting added time and effort.

4. Perform Conditional Code with Ternary Operators

It is a typical method among developers to perform conditional code with If/Else proclamations. But the developers need to write extra code to perform conditional code through If/Else proclamations. They can surely avoid writing extra code by performing conditional code through ternary operator instead of If/Else proclamations. The ternary operator supports programmers to keep the code fresh and clutter-free by writing conditional code in a separate line.

5. Look at Comparable Functions

The developers can utilize native functions to keep the PHP code clean and clear. But they should recall that the execution speed of individual PHP functions varies. Likewise, specific PHP functions expand further resources than others. Subsequently, the developers must think about comparable PHP functions and take the one that does not influence the execution of the web application negatively and expend extra resources. For example, they should determine the length of a line by using isset() instead of strlen(). Notwithstanding being quicker than strlen(), isset() additionally remains legitimate paying little mind to the presence of factors.

6. Turn Error Reporting on Being Developed Mode

The developers must identify and fix all errors or imperfections in the PHP code during the development mode. They need to put extra time and try to fix the coding errors and problems identified during the testing procedure. The programmers set the error reporting to E_ALL to recognize both minor and vital errors in the PHP code during the development mode. However, they should fix the error reporting choice when the application moves from development mode to generation mode.


7. Use JSON instead of XML 

While working with web services, the programmers have the choice to use both XML and JSON. But they can exploit the native PHP functions like json_encode( ) and json_decode( ) to work with web services more quickly and effectively. Despite everything, they have the prospect to work with XML type of data. The programmers can parse the XML data all the more productively by using a common expression instead of DOM manipulation.

8. Avoid Performing Database Queries in Loop 

The programmers can rapidly improve the web application’s execution by not performing database queries in a loop. They likewise have a few choices to fulfill similar outcomes without executing database queries in a loop. For instance, the developers can utilize a powerful WordPress plug-in like Query Monitor to see the database queries alongside the columns affected by them. They can even utilize the debugging plug-in to identify the slow, copy, and mistaken database queries.

9. Avoid Utilizing Wildcards in SQL Queries 

The programmers usually utilize wildcards or to keep the SQL queries conservative and clear. But the utilization of wildcards may influence the execution of the web application straightforwardly if the database has a more significant number of columns. The programmers must specify the expected columns specifically in the SQL query to keep data safe and lessen resource utilization.

10. Pass References instead of Quality to Functions

The expert programmers never announce new classes and strategies just when they become necessary. They likewise search for approaches to reuse the classes and strategy all through the code. However, they also comprehend the way that a function can be controlled rapidly by passing references instead of qualities. They can additionally avoid adding additional overheads by giving references to the function instead of qualities. However, despite everything they have to make sure that the philosophy remains unchanged while passing a reference to the functions.

11. Follow Double Quotes with Single Quotes

While writing PHP code, programmers have a choice to utilize either single quotes (‘) or double quotes (“). But the developers can rapidly improve the execution of the PHP application by using single quotes instead of double quotes. The single code will increase the execution speed of loops radically. In like manner, the single quote will additionally empower programmers to print longer lines of data all the more productively. However, the developers need to make changes to the PHP code while using single quotes instead of double quotes.

12. Never Belief User Input

The programmers keep the web application secure by never trusting the input put together by users. They generally check, filter and purify all user information to cover the application from varying security warnings. They can additionally keep users from submitting inappropriate or invalid information by using built-in functions like filter_var(). The function will check for fitting qualities while taking or processing user input.


However, it is also essential for web developers to select the privilege PHP framework and development tool. At present, every programmer has the choice to browse an extensive variety of open source PHP frameworks including Laravel, Symfony, CakePHP, Yii, CodeIgniter, and Zend. Henceforth, it becomes significant for programmers to choose a PHP that complements all requirements of a project. They likewise need to connect many PHP development tools to lessen the development time significantly and make the web application maintainable.
