Re: [PHP] Counting elements in an array
$i = 0;
foreach ($fruit as $k)
if ('prange' == $k)
$i++;

How would I count the number of elements in an array that had a certain
value?
In other words, if I have
$fruit = array(orange,orange,apple,bananna,orange,apple,pear);
How could I get the number of elements from $fruit where the value is
orange?
Thanks,
Jeff
