Description:
------------
The php.ini setting display_errors seems to be ignored; no errors are displayed, even if display_errors is turned on.

Reproduce code:
---------------
<?php
echo ini_get("display_errors") . "<br/>";
echo $foo . "bar";
$foo[bar] = "phpinfo()";
?>

Expected result:
----------------
There should be warning messages about $foo being undefined and the constant "bar" being undefined.

Actual result:
--------------
Output is:
1
bar

As far as I know, the first line being 1 means that display_errors is on.
