The array_search() function search an array for a value and returns the key.

array Required. Specifies the array to search in
strict Optional. Possible values:

When set to true, the number 5 is not the same as the string 5 (See example 2)
Example 1
<?php
$a=array("a"=>"Dog","b"=>"Cat","c"=>"Horse");
echo array_search("Dog",$a);
?>
The output of the code above will be:
a
Example 2
<?php
$a=array("a"=>"5","b"=>5,"c"=>"5");
echo array_search(5,$a,true);
?>
