[PHP-DEV] Bug #14687 Updated: Ignoring @'s after set_error_handler() is used From: matthew_dean <email protected>
Date: 12/31/01

ID: 14687
User updated by: matthew_dean <email protected>
Reported By: matthew_dean <email protected>
Status: Closed
Bug Type: Scripting Engine problem
Operating System: Redhat 7.0, Solaris 7
PHP Version: 4.0.6
New Comment:

Ah, ok, thanks. - I understand now. It was only the meaning of the @ operator I didn't follow.

I'd misinterpreted the docs.

I thought that prepending an @ set the errorNum to 0 ( either that or it suppressed the call to the error handler), when in fact it sets the global error level to 0 for the  <email protected> expression.

I thought the @ was: 'Supress errors'

Actually it's: 'Trigger an error as normal, but with the error level temporarily set to 0'

Thanks,
Matt

It's the programmer's responsibility to honor error_reporting in the error handler. The error handler will be called even if the error that occured is not inside the error_reporting mask - to allow you to conduct logging, recovery, etc.

You can easily honor it by using the return value of error_reporting(), and compare it (using &) with the error level that you got.

<?php
  function myErrorHandler($errorNum) {
    echo "$errorNum\n";
  }
  set_error_handler("myErrorHandler");
  #error_reporting (E_ALL);#doesn't change the bug behaviour
  @$j=$i;
?>

This echos:
8

Yet according to: http://www.php.net/manual/en/function.set-error-handler.php

"Of particular note is that this value will be 0 if the statement that caused the error was prepended by the @ error-control operator. "

I've tried this on 4.0.4pl1 and 4.0.6
The changelog for 4.1.0 doesn't mention a fix.

The @ works fine for lines executed before set_error_handler().

Here's one of the configure lines, though (to me) it doesn't seem likely to be a compiley issue...

'./configure' '--with-db' '--enable-dba' '--with-gdbm' '--with-xml' '--with-oci8=/usr/local/oracle/' '--with-apxs=/usr/local/apache-1.3.14/bin/apxs' '--with-mysql=/usr/local/mysql' '--with-gd' '--with-sablot'

Thanks!
