array search not working

[Destramic]

ive tried this simple script and its not coming true...for some reason it doesnt search the first key if anyone can help please?

 

$array = array(0 => 'blue', 1 => 'red', 2 => 'green', 3 => 'red');

$key = array_search('blue', $array);

		if ($key)
		{
			echo hi;
		}

array_search returns the key, so in your case it's returning 0, which evaluates to false. You need to use !== operator.

 

if($key !== false) {

}

Or you can use in_array() function which will return true/false.

 

if(in_array('blue',array))

{

    echo 'hi';

}
