If you are debugging json or ajax applications, you may find the following error handler usefull. It
should be used for php generated javascript files only. The html-tags are just meant to be a display
hint for a webbrowser when it does not know it is displaying javascript.
Please understand that the error message is only shown by the browsers js interpreter, if the
instruction flow passes the position of the error.
If you don't have php-json (you should get it from http://www.aurore.net/projects/php-json/) remove
the line with 'json_encode' or use an encoder of your own choice.
<?php function myErrorHandler($errno, $errstr, $errfile, $errline, $context)
{
$a = "/*<b>PHP Error Handler:</b><pre>*/\nalert('PHP";
$e = "\\n".addslashes($errstr).'\\n';
$e.= " =>In line $errline of file ".addslashes($errfile)."');\n";
$e.= 'alert (\'Context:'.str_replace
('\\n',"\\n'+\n'",json_encode (print_r
($context,true)))."');\n";
$e.= "debugger;<*</pre>*/";
switch ($errno) {
case E_ERROR:
echo "$a ERROR: $e";
exit(1);
case E_WARNING:
echo "$a WARNING: $e";
exit(1);
case E_NOTICE:
echo "$a NOTICE: $e";
break;
default:
echo "$a OTHER($errno): $e";
}
} ?>
