session_write_close

Function name: session_write_close()

Applicable versions: All versions

Usage: The session_write_close() function is used to write the current session data and end the session. It is usually called immediately after using session data to ensure that session data is saved and session lock is released to allow other scripts to access the same session data.

Example: <?php session_start();

// Set session data $_SESSION['username'] = 'JohnDoe'; $_SESSION['age'] = 30;

// Use session data

// Write and close the session session_write_close();

// Can other scripts access the same session data?> In the above example, the session_write_close() function is used to write session data and end the session. After the function is called, the session data will be saved and the session lock will be released, allowing other scripts to access the same session data. Note that if you try to modify the session data after calling the session_write_close() function, these modifications will not be saved. Therefore, it is recommended to call this function immediately after using session data to ensure data storage and release session lock operations.
