How to implement array paging in PHP?
Article Introduction：In PHP, array paging can be implemented through the paginateArray function. This function accepts an array, the number of items per page, and the current page number, and returns the data of the corresponding page. Example of usage: $myArray=range(1,100);$perPage=10;$currentPage=3;$pagedData=paginateArray($myArray,$perPage,$currentPage); Output the data on page 3, that is, 21 to 30.

How do you loop through all the values stored in a PHP session?
Article Introduction：In PHP, iterating through session data can be achieved through the following steps: 1. Start the session using session_start(). 2. Iterate through foreach loop through all key-value pairs in the $_SESSION array. 3. When processing complex data structures, use is_array() or is_object() functions and use print_r() to output detailed information. 4. When optimizing traversal, paging can be used to avoid processing large amounts of data at one time. This will help you manage and use PHP session data more efficiently in your actual project.

What are the differences between $_GET, $_POST, and $_REQUEST superglobals, and when should each be used?
Article Introduction：In PHP, $_GET, $_POST, and $_REQUEST are used to collect data from HTTP requests, but for different purposes. 1.$_GET is used to retrieve non-sensitive data through URL query strings, suitable for scenarios such as filtering content, paging links, etc.; 2.$_POST is used to process sensitive or large amounts of data submitted through HTML forms, such as login information and file uploads; 3.$_REQUEST is a collection of $_GET, $_POST and $_COOKIE, providing a unified access method, but may cause conflicts. It is recommended to use $_GET or $_POST first to avoid ambiguity and security risks.
