PHP treats all arrays as associative, so there aren't any built in functions. Can anyone recommend a fairly efficient way to check if an array contains only numeric keys?
Basically, I want to be able to differentiate between this:
$sequentialArray = array('apple', 'orange', 'tomato', 'carrot');
and this:
$assocArray = array('fruit1' => 'apple',
'fruit2' => 'orange',
'veg1' => 'tomato',
'veg2' => 'carrot');
