Isolde is kind of wrong. The error handlers are stacked with set_error_handler(), and popped with restore_error_handler(). Here i put an example:

<?php
mysql_connect
("inexistent"); //Generate an error. The actual error handler is set by default

function foo1() {echo "<br>Error foo1<br>";}
function
foo2() {echo "<br>Error foo2<br>";}
function
foo3() {echo "<br>Error foo3<br>";}

set_error_handler("foo1"); //current error handler: foo1
set_error_handler("foo2"); //current error handler: foo2
set_error_handler("foo3"); //current error handler: foo3

mysql_connect("inexistent");
restore_error_handler(); //now, current error handler: foo2
mysql_connect("inexistent");
restore_error_handler(); //now, current error handler: foo1
mysql_connect("inexistent");
restore_error_handler(); //now current error handler: default handler
mysql_connect("inexistent");
restore_error_handler(); //now current error handler: default handler (The stack can't pop more)
?>
