ある hosting site で、例として載っていた php tips。もし、レンタルサーバーで、php.ini をいじることが出来なくて、でも trigger_error を使ったデバッグがしたい時にとても有効。
使い方は、このファイルを、デバッグしたいファイルの先頭で include すればいいだけ。標準では errors.csv というファイルが、実行中ファイルと同じフォルダに出来ます。まぁ、本当はその辺もちゃんと制御できたらいいんでしょうけど、trigger_error デバッグできる人なら、このソースをいじって、直せると思います。
以下 code 中、back slash が円マーク変換されている可能性もありますが、その辺も読み替えて下さいね。
error_handling.php
error_reporting(0);
$old_error_handler = set_error_handler("userErrorHandler");
function userErrorHandler ($errno, $errmsg, $filename, $linenum, $vars)
{
$time=date("d M Y H:i:s");
// Get the error type from the error number
$errortype = array
(
1 => "Error",
2 => "Warning",
4 => "Parsing Error",
8 => "Notice",
16=> "Core Error",
32=> "Core Warning",
64=> "Compile Error",
128=> "Compile Warning",
256=> "User Error",
512=> "User Warning",
1024 => "User Notice"
);
$errlevel=$errortype[$errno];
//Write error to log file (CSV format)
$errfile=fopen("errors.csv","a");
fputs($errfile,"¥"$time¥",¥"$filename: $linenum¥",¥"($errlevel) $errmsg¥"¥r¥n");
fclose($errfile);
//Terminate script if fatal error
if( ($errno!=2) && ($errno!=8) && ($errno!=32) && ($errno!=128) && ($errno!=256) && ($errno!=512) && ($errno!=1024) ) {
die("A fatal error has occured. Script execution has been aborted.¥n");
}
}

Regardless of the brands, tennis shoes last well only with regular cleaning. In fact, they need special cleaning process for their maintenance. As far as possible, it is better to keep your shoes away from dirt. However, weekly cleaning and thorough drying is essential. Well, it`s really a nice idea to clean your tennis shoes immediately
