Phpignore_user_abort () to implement the task scheduler function

Syntax:Ignore_user_abort (setting)

Parameters:Setting is optional.

Description:If it is set to true, the disconnection from the user is ignored. if it is set to false, the script stops running. If this parameter is not set, the current setting is returned.

Tips and comments

Note:Php does not detect whether the user is disconnected until it attempts to send messages to the client. Simply using the echo statement cannot ensure message sending. For more information, see flush.

Of course, to keep the program running, you must add set_time_limit (0 );

Every time we access the php script, we get the returned result after all the php scripts are executed. if we need a script to run continuously, we need to use php persistent connection.
