New Comment:
If I understand, this function should return the legth of the match.
But it seems it has a bug, because it always return 1 if you don't pass
the 3rd parameter. Or is it a feature that should be documented?
<?
echo ereg('foo', 'foo foo foo'); //1
echo ereg('foo', 'foo foo foo', $var); //3
echo ereg('foobar', 'foobar foo foo', $var2); //6
?>

ereg() still only returns int(1) or (boolean)FALSE. I've expanded my
test-script a bit:
<?php
$a = ereg("fo","fo"); // Simple test to see if documentation is right
(it's not)
$b = ereg("bar","foobarbar"); // Is it the position of the first
result, that is returned ? (no)
$c = ereg("foo","bar"); // A negative test (works)
echo $a . ":" . gettype($a). "\n";
echo $b . ":" . gettype($b). "\n";
echo $c . ":" . gettype($c). "\n";
?>
Result:
1:integer
1:integer
:boolean
According to the docs, it should be:
2:integer
3:integer
:boolean

This bug has been fixed in the documentation's XML sources.
The changes may not appear immediately, since the online and
downloadable versions of the documentation need some time to get
updated. We would therefore like to ask for your patience in this
matter.
Thank you for the report, and for helping us make our documentation
better.

ereg() returns the length of the matched string on success,
the documentation is wrong.
