where ever the internal pointer of the array points, there's a function
called reset that - suprisingly resets the array pointer to the primary
element of the array.
Try the following example:
<?php
$fruits = array(
'fruit1' => 'apple',
'fruit2' => 'orange',
'fruit3' => 'grape',
'fruit4' => 'apple',
'fruit5' => 'apple',
);
reset($fruits);
$key = key($fruits);
$value = current($fruits);
echo "$key = $value";
?>
That should be sort of what you wanted.
