![]() ![]() The only difference is that the include() statement generates a PHP alert but allows script execution to proceed if the file to be included cannot be found. In most cases, the require() statement works in the same way as the include() statement. As a result, it will issue an alert about the missing file while also showing the production. The Main.php file isn't in the same directory as the other files we've included. Include allows the script to proceed if the file is missing or inclusion fails, but require causes the script to halt, resulting in a fatal E_COMPILE_ERROR level error. ![]() The terms "include" and "require" are interchangeable. Since scripts do not execute if files are missing or misnamed, the require() function is recommended over include(). So, apart from how they treat error conditions, require() and include() are identical. The require() function produces a fatal error and stops the script's execution if there is a problem loading a file. The require() function copies all of the text from a given file into the file that uses the include function. The only difference is that if the file is not found, it prevents the script from running, while include does not. The PHP require function is similar to the include function, which is used to include files. php has been included with the help of line Output: In the above code, there are two files, that is. The below example code will demonstrate the concept of PHP include. While including the content of the included file will be displayed in the main file. Include is a keyword to include one PHP file into another PHP file. Easy to Edit: If you want to alter anything on a website, you can modify the source file used with all of the web pages rather than editing each file individually. ![]() Code Reusability: We may reuse HTML code or PHP scripts in several PHP scripts with the aid of the ‘include’ and ‘require’ build.It produces an alert if there is a problem loading a file however, the script will still run. The include() function copies all of the text from a given file into the file that uses the include function. This will help prevent the application's protection and reputation from being jeopardized if one key file is corrupted. Otherwise, always use the required declaration to include the main file in the flow of execution while coding Framework, CMS, or a complex PHP program. If the include statement appears, execution should continue and show users the output even if the include file is missing. Require will produce a fatal error (E_COMPILE_ERROR) and interrupt the script.Include in PHP will only generate an alert (E_WARNING), and the script will proceed.Except in the case of failure, the ‘include’ and ‘require statements’ are identical: In this PHP include example, we are going to use a relative path, using the WordPress build in function: get_stylesheet_directory().The ‘include’ or ‘require’ statement can be used to insert the content of one PHP file into another PHP file (before the server executes it). How to include a PHP file in a WordPress child theme In this PHP include example, we are going to use a relative path, using the WordPress build in function: get_template_directory. How to include a PHP file in a WordPress theme If you are using a child theme, then you would have to use the WordPress function: get_stylesheet_directory() instead, to get the absolute path to the child theme directory. In case you are using a child theme, the absolute path to the parent theme directory will be returned – and this will not work. ![]() In case you are using a WordPress child theme The build-in WordPress function get_template_directory, retrieves the current theme directory by returning an absolute server path (eg: /home/user/public_html/wp-content/themes/my_theme), and not a URI. The WordPress get_template_directory() function Using a relative path (best practice) – the path related to the present working directly(pwd), starting at your current directory and never starts with a “/”.Using a absolute/static path (not recommended) – specifying the location of a file or directory from the root directory(/).There are multiple ways to go about this, such as: When you want to include a PHP file (or image file, HTML file, etc.), it is required to specify a specific path that instructs the webserver, on where the webserver should locate the specific file. Why you should choose a relative path and not an absolute/static path This snippet isn’t so much a “WordPress snippet”, but really just the PHP include function, using WordPress get_template_directoryto get the relative path for the file. This little “PHP include” guide, will show you how to include a PHP-file in your WordPress theme (using a relative path). ![]()
