offset

-Status: Critical
+Status: Closed
Bug Type: Scripting Engine problem
Operating System: Any
PHP Version: 4.0CVS-2001-11-15
Assigned To: derick
New Comment:
It's not a bug, $foo{3}. "\n" is done before the @, so that displays
the error.
so I'm closing this, this works BTW:
$foo = "foo"; echo @($foo{3}. "\n");

Btw, this breaks BC:
[chroot] mfischer@ficken:~/isrc/cvs/php4/Zend$ php -v
4.0.6-dev
[chroot] mfischer@ficken:~/isrc/cvs/php4/Zend$ php -q
<? error_reporting(E_ALL); $foo = ''; isset($foo[2]);?>
[chroot] mfischer@ficken:~/isrc/cvs/php4/Zend$
and with RC4:
mfischer@ficken:~/isrc/cvs/php4/Zend$ php -v
4.1.0RC4
mfischer@ficken:~/isrc/cvs/php4/Zend$ php -q
<? error_reporting(E_ALL); $foo = ''; isset($foo[2]);?>
<br>
<b>Warning</b>: Uninitialized string offset: 2 in <b>-</b> on line
<b>1</b><br>
-(1) : Warning - Uninitialized string offset: 2
mfischer@ficken:~/isrc/cvs/php4/Zend$
Marking as critical.

'isset($foo[0])' issues a warning too if $foo is an emtpy string.
------------------------------------------------------------------------
[2001-11-15 02:33:34] [EMAIL PROTECTED]
When setting error_reporting(E_ALL) the following occurs:
<?
error_reporting(E_ALL);
$foo = array(); echo $foo[0] . "\n"; // <-- warning
$foo = array(); echo @$foo[0]. "\n"; // <-- no warning
$foo = "foo"; echo $foo{3} . "\n"; // <-- warning
$foo = "foo"; echo @$foo{3}. "\n"; // <-- still warning
?>
The last line should not emit a warning.
