I am not interested in the values in the arrays, how can I discard them?
<?php
$values = array(10=>"I","Don't","Care","About","Values");
print_r($values);
$whatvalues = array_keys($values);
print_r($whatvalues);
?>
Here is the resultant output from this:
Array
(
[10] => I
[11] => Don't
[12] => Care
[13] => About
[14] => Values
)
Array
(
[0] => 10
[1] => 11
[2] => 12
[3] => 13
[4] => 14
)
We can see that the values have been discarded and we now have an array containing the keys as the values.
