(PHP 4, PHP 5)
ignore_user_abort — Set whether a client disconnect should abort script execution
Sets whether a client disconnect should cause a script to be aborted.
If not set, the function will only return the current setting.
Returns the previous setting, as a boolean.
PHP will not detect that the user has aborted the connection until an attempt is made to send information to the client. Simply using an echo statement does not guarantee that information is sent, see flush().
