error_clear_last — Clear the most recent error
Clears the most recent errors, making it unable to be retrieved with error_get_last() .
Example #1 An error_clear_last() example
<?php
var_dump ( error_get_last ());
error_clear_last ();
var_dump ( error_get_last ());
@ $a = $b ;
var_dump ( error_get_last ());
error_clear_last ();
var_dump ( error_get_last ());
?>
以上例程的输出类似于:
NULL NULL array(4) { ["type"]=> int(8) ["message"]=> string(21) "Undefined variable: b" ["file"]=> string(9) "%s" ["line"]=> int(6) } NULL
