PHP通过Eamil邮件发送出错信息，觉得不是很常用，不过做为经常搞PHP项目，先留着自己以后参考。
<?php
//自定义处理程序
function nettuts_error_handler($number, $message, $file, $line, $vars){
$email = "
<p>An error ($number) occurred on line
<strong>$line</strong> and in the <strong>file: $file.</strong>
<p> $message </p>";
$email .= "<pre>" . print_r($vars, 1) . "</pre>";
$headers = 'Content-type: text/html; charset=iso-8859-1' . "\r\n";
error_log($email, 1, 'you@youremail.com', $headers);
if ( ($number !== E_NOTICE) && ($number < 2048) ) {
die("有错误，请稍后再试！.");
}
}
set_error_handler('nettuts_error_handler');
echo $somevarthatdoesnotexist;
?>
