search a php array for partial string match

Question

I have an array and I\'d like to search for the string \'green\'. So in this case it should return the $arr[2]

$arr = array(0 =>

You can use preg_grep function of php. It's supported in PHP >= 4.0.5.

$array = array(0 => 'blue', 1 => 'red', 2 => 'green string', 3 => 'red');
$m_array = preg_grep('/^green\s.*/', $array);

$m_array contains matched elements of array.
