PHP tips to improve your programming skills

PHP is a programming language developed with built-in web development capabilities. The new language features included in PHP 7 make it easy for programmers to greatly improve the speed of their web application without using additional resources. Programmers can switch to the latest version of the widely used server-side scripting language to improve site loading speed without spending more time and effort. But web application developers still need to focus on the ability and reusability of PHP code to maintain and update web applications quickly in the future.

12 tips for writing clean, reusable and reusable PHP code

1) Take advantage of the original posts

While writing PHP code, programmers have the option to achieve the same goal using either native or custom functions. But developers must take advantage of the built-in functions that PHP provides to accomplish a variety of tasks without writing additional code or custom functions. The original functionality will help developers keep the app icon clean and readable. They can easily collect and use information about the original functions by referring to the PHP User's Guide.

2) Comparing similar functions

Developers can use local functions to keep PHP code readable and clean. But they should remember that the speed with which individual PHP functions are implemented varies. Also, some PHP functions consume additional resources than others. Thus, developers should compare similar PHP functions, and choose the functionality that does not negatively affect web application performance and consumes additional resources. For example, they must specify the length of the string using isset () instead of strlen (). In addition to being faster than strlen (), isset () also remains valid regardless of the presence of variables.

3) Most PHP scripts cache

PHP programmers must remember that the script execution time varies from one web server to another. For example, the Apache web server provides an HTML page that is much faster than PHP scripts. Also, you should recompile the PHP script every time the page is requested. Programmers can easily remove the script's recompilation process by storing most scripts. They also have an option to dramatically reduce text aggregation time using a variety of PHP cache tools. For example, programmers can efficiently use memcache to buffer a large number of scripts, as well as reduce database interactions.

4) Executing conditional code with Ternary operators

It is common practice for PHP developers to implement conditional code with If / Else statements. However, developers have to write additional code to implement conditional code with If / Else statements. They can easily avoid writing additional code by executing conditional code through the triple operator instead of If / Else statements. Triple Launcher helps programmers keep code clean and clutter-free by writing conditional code in one line.

5) Maintain and read code readable

Programmers often find it difficult to understand and modify the code written by others. Hence, they need additional time to maintain and update PHP applications efficiently. While writing PHP code, programmers can make it easy for the app to update and update easily by clearly describing the use and importance of individual code snippets. They can easily make the code readable by adding comments to each code snippet. Comments will facilitate other developers to make changes to the existing code in the future without taking more time and effort.

6) Use JSON instead of XML

While working with web services, PHP programmers have an option to use both XML and JSON. But they can always take advantage of native PHP functions like json_encode () and json_decode () to work with web services in a faster and more efficient way. They still have an option to work with the XML data format. Programmers can more efficiently parse XML data using a regular expression rather than a DOM manipulation.

7) Pass references instead of value to functions

Experienced PHP programmers do not announce new classes and methods only when they become necessary. They are also exploring ways to reuse chapters and methods via code. However, they also understood the fact that the function could be quickly processed by passing references instead of values. They can also avoid adding additional expenses by passing references to the job rather than the values. However, they still have to make sure that the logic remains unaffected while passing the signal to the jobs.

8) Turn on the error reporting in development mode

Developers should identify and fix all errors or defects in PHP code during the development process. They should also take more time and effort to fix coding errors and specific issues during the testing process. Programmers simply set error reporting to E_ALL to identify both minor and major errors in the PHP code during the development process. However, they should turn off the error reporting option when the app goes from development mode to production mode.

9) Replace double quotes with single quotes

While writing PHP code, programmers have an option to either use single quotes (& # 39;) or double quotes ("). However, developers can easily improve PHP application performance by using single quotes instead of double quotes. Quick loop implementation Significantly, likewise, single quotes will enable programmers to print longer lines of information more efficiently, however, developers have to make changes to PHP code while using single quotes instead of double quotes.

10) Avoid using wildcards in SQL queries

PHP programmers often use wildcards or * to keep SQL queries merged and simple. However, the use of wildcards may directly affect the performance of a web application if the database contains more columns. Programmers should mention the columns specifically required in an SQL query to maintain data security and reduce resource consumption.

11) Avoid executing database queries in a loop

PHP programmers can easily optimize web application performance by not executing database queries in a loop. They also have a number of options to achieve the same results without performing database queries in the loop. For example, developers can use a powerful WordPress component such as Query Monitor to display database queries alongside the rows that are affected by them. They can even use the debug component to define slow, redundant, and wrong database queries.

12) Do not trust user input

Smart PHP programmers keep their web app safe by never trusting user input. They always verify, filter, and sterilize all user information to protect the app from various security threats. They can also prevent users from sending inappropriate or invalid data by using built-in functions like filter_var (). The job will search for appropriate values ​​while receiving or processing user input.

However, it is also important for web developers to choose the appropriate PHP framework and development tool. Nowadays, every programmer has an option to choose from a wide range of open source PHP frameworks including Laravel, Symfony, CakePHP, Yii, CodeIgniter and Zend. Thus, it becomes necessary for programmers to choose PHP that complements all of the project's needs. They also need to combine multiple PHP development tool to greatly reduce development time and make the web application maintainable.
