explode uses one string to split another string
Basic syntax of explode function:
<span>array</span> <span>explode</span> ( <span>string</span> <span>$delimiter</span> , <span>string</span> <span>$string</span> [, int <span>$limit</span> ] )
The explode function returns an array composed of strings. Each element is a substring of string, and they are separated by the string delimiter as a boundary point.
explode parameter introduction:
|
Description | ||||||||
delimiter | Required. separator character. | ||||||||
string | Required. The string that needs to be split. | ||||||||
limit | Optional. If the limit parameter is set and is positive, the returned array contains at most limit elements, and the last element will contain the remainder of the string. If the limit argument is negative, all but the last -limit elements are returned. If limit is 0, it will be treated as 1. |
explode return value:
This function returns an array composed of strings. Each element is a substring of string, and they are separated by the string delimiter as a boundary point.
If delimiter is an empty string (""), explode() will return FALSE . If delimiter contains a value not found in string and a negative limit is used, an empty array is returned, otherwise an array containing a single element of string is returned.

Session in PHP is a mechanism for saving user data on the server side to maintain state between multiple requests. Specifically, 1) the session is started by the session_start() function, and data is stored and read through the $_SESSION super global array; 2) the session data is stored in the server's temporary files by default, but can be optimized through database or memory storage; 3) the session can be used to realize user login status tracking and shopping cart management functions; 4) Pay attention to the secure transmission and performance optimization of the session to ensure the security and efficiency of the application.

Absolute session timeout starts at the time of session creation, while an idle session timeout starts at the time of user's no operation. Absolute session timeout is suitable for scenarios where strict control of the session life cycle is required, such as financial applications; idle session timeout is suitable for applications that want users to keep their session active for a long time, such as social media.

The server session failure can be solved through the following steps: 1. Check the server configuration to ensure that the session is set correctly. 2. Verify client cookies, confirm that the browser supports it and send it correctly. 3. Check session storage services, such as Redis, to ensure that they are running normally. 4. Review the application code to ensure the correct session logic. Through these steps, conversation problems can be effectively diagnosed and repaired and user experience can be improved.
