Parameter | Description |
---|---|
error | Required. The error message to log |

headers | Optional. Only used if the "type" parameter is "1". Specifies additional headers, like From, Cc, and Bcc. The additional headers should be separated with a CRLF (\r\n).Note: When sending an email, it must contain a From header. This can be set with this parameter or in the php.ini file. |
example:
$test=2;
if ($test>1){error_log("A custom error has been triggered",1,"someone@example.com","From: webmaster@example.com");}?>
Output:
A custom error has been triggered

2 | E_WARNING | Non-fatal run-time errors. Execution of the script is not halted |
4 | E_PARSE | Compile-time parse errors. Parse errors should only be generated by the parser |
8 | E_NOTICE | Run-time notices. The script found something that might be an error, but could also happen when running a script normally |

//Report all errorserror_reporting(E_ALL);?>

//custom error handler functionfunction customError($errno, $errstr, $errfile, $errline) { echo "Custom error: [$errno] $errstr
"; echo " Error on line $errline in $errfile
"; }
//set user-defined error handlerset_error_handler("customError");
$test=2;
//trigger errorif ($test>1) { trigger_error("A custom error has been triggered"); }
//restore built-in error handlerrestore_error_handler();
//trigger error againif ($test>1) { trigger_error("A custom error has been triggered"); }?>
Output

if thats website don't have XSS filtering, when the comment appear, the alert script will working.
In PHP there are so many function, where we can use for xss attack filtering, and we can combine to make own xss filtering function
function xss_filtering($text) {
$f = stripslashes (strip_tags (htmlspecialchars ($text, ENT_QUOTES)));
return $f;
}
$text_comment = xss_filtering($_POST['comment']);
