Matching data between two arrays

[Omzy]

Why does this not work:

 

$subcats=array(
'wedding-cakes'=>array('cakes', 'Wedding Cakes'),
'birthday-cakes'=>array('cakes', 'Birthday Cakes')
);

 

$cat=array(
'cakes'=>array('Cakes', 'Wedding Cakes, Birthday Cakes')
);

 

foreach($subcats as $index1 => $value1)
if($subcats[$index1][0] == $cat)
{
//echo $subcats[$index1][1];
}
