Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to
report
a bug at http://bugs.php.net/how-to-report.php
You have to use "!==" operator when you want to distinguish 0 and
false.

I try to find some entry in an Array beginning with
index 0. I test for false to treat the "not found" event
but don´t find my entrys in the first line.
If i test for 0 i always end up with my fist line.
$this->wochentage_name=array(
array(0,"Monday","Montag","Mo"),
array(1,"Tuesday","Dienstag","Di"),
array(2,"Wednesday","Mittwoch","Mi"),
array(3,"Thursday","Donnerstag","Do"),
array(4,"Friday","Freitag","Fr"),
array(5,"Saturday","Samstag","Sa"),
array(6,"Sunday","Sonntag","So")
);
for($i=0;$i<sizeof($this->wochentage_name);$i++)
{
print_r($this->wochentage_name[$i]);
echo "ENDE für Nummer".$i."<br>";
$key = array_search($in,$this->wochentage_name[$i]);
if($key != 0)
{
return $this->wochentage_name[$i][$row];
}
}
