Like $php_errormsg, the return value of this function may not be updated if a user-defined error handler returns non-FALSE. Tested on PHP 5.2.6.



<?php

var_dump(PHP_VERSION);

// Outputs: string(5) "5.2.6"



@trigger_error("foo");

$e=error_get_last();

var_dump($e['message']);

// Outputs: string(3) "foo"



set_error_handler(create_function('$a,$b',''));



@trigger_error("bar");

$e=error_get_last();

var_dump($e['message']);

// Outputs: string(3) "foo"



set_error_handler(create_function('$a,$b','return false;'));



@trigger_error("baz");

$e=error_get_last();

var_dump($e['message']);

// Outputs: string(3) "baz"

?>

It can't be completely reset, but you can "clear" it well enough for all practical purposes:

<?php

@trigger_error("");

// do stuff...

$e=error_get_last();

if($e['message']!==''){

    // An error occurred

}

?>

This function is pretty useless, as it can not be reset, so there is no way to know if the error really happened on the line before this function call.
