tick is called.
callbackThe function to register.
args
| Version | Description |
|---|---|
| 8.5.0 | Tick handlers are now deactivated later during request shutdown: after all shutdown functions and destructors have run, and after the output handlers have been cleaned up. Previously they were deactivated at the very beginning of request shutdown, so tick functions were no longer called during shutdown functions, destructors, or output handling. See the migration guide for details. |

<?php
declare(ticks=1);
function my_tick_function($param) {
echo "Tick callback function called with param: $param\n";
}

?>
