PHP sends an error log to the servers logging system or a file, depending on the error_log configuration in the php.ini file. But this can be changed using the error_log() function, ie you caqn send error logs to a file or a remote destination, specified by you.

You can also send error messages to yourself by e-mail. This is a good way of getting notified of specific errors.

Send an Error Message by E-Mail

In the example below we will send an e-mail with an error message and end the script, if a specific error occurs:

<?php //error handler function
function customError($errorNo, $errorStr)
{
echo “<b>Error:</b> [$errorNo] $errorStr<br />”;
echo “Webmaster has been notified”;
error_log(”Error: [$errorNo] $errstr”,1,
“user1@example.com”,”From: tutor@goweb99.com”);
}
//set error handler
set_error_handler(”customError”,E_USER_WARNING);
//trigger error
$test=2;
if ($test>1)
{
trigger_error(”Value must be 1 or below”,E_USER_WARNING);
}
?>

Output:

Error: [512] Value must be 1 or below
Webmaster has been notified

And the mail received from the code above looks like this:

Error: [512] Value must be 1 or below
