Getting Keys/Values Separately From Associative Array

If you somehow need to get either only the keys or values of an associative array, you can do so with help of “array_keys” or “array_values” functions. See the example below:

1 2 3 4 5

$my_array = array("key1"=>"value 1","key2"=>"value 2","key3"=>"value 3");   print_r(array_keys($my_array)); echo "<br>"; print_r(array_values($my_array));
