ignore_user_abort

(PHP 4, PHP 5, PHP 7)
Set whether a client disconnect should abort script execution
int ignore_user_abort ([ bool $value ] )

Sets whether a client disconnect should cause a script to be aborted.

When running PHP as a command line script, and the script's tty goes away without the script being terminated then the script will die the next time it tries to write anything, unless value is set to TRUE

Parameters:
value

If set, this function will set the ignore_user_abort ini setting to the given value. If not, this function will only return the previous setting without changing it.

Returns:

Returns the previous setting, as an integer.

Examples:
A ignore_user_abort() example
<?php
// Ignore user aborts and allow the script
// to run forever
ignore_user_abort(true);
set_time_limit(0);

echo 'Testing connection handling in PHP';

// Run a pointless loop that sometime 
// hopefully will make us click away from 
// page or click the "Stop" button.
while(1)
{
    // Did the connection fail?
    if(connection_status() != CONNECTION_NORMAL)
    {
        break;
    }

    // Sleep for 10 seconds
    sleep(10);
}

// If this is reached, then the 'break' 
// was triggered from inside the while loop

// So here we can log, or perform any other tasks
// we need without actually being dependent on the 
// browser.
?>
