Search an array for a matching string

Question

I am looking for away to check if a string exists as an array value in an array is that possible and how would I do it with PHP?

Answer 1

You can use PHP's in_array function to see if it exists, or array_search to see where it is.

Example:

$a = array('a'=>'dog', 'b'=>'fish');

in_array('dog', $a); //true
in_array('cat', $a); //false

array_search('dog', $a); //'a'
array_search('cat', $a); //false
