php parsing certain values within long text?

Question

I have an array of values, I was wondering how I can parse certain words if the words in my array has the value i'm looking for plus more text?

example:

I'm looking for rest

Array values has

restful
myrestless
rests
resting

What php function, if any, can I use where it will show that there are 4 items that has the word rest?

Thanks in advance!

Use array_filter:

$array = array('restful', 'myrestless', 'rests', 'resting');

$needle = 'rest';
$rest_array = array_filter( $array, 
    function( $el) use( $needle) { 
        return !(strpos( $el, $needle) === false); 
    }
);
var_dump( $rest_array);

Note that this requires PHP >= 5.3 (maybe 5.4?). Otherwise you will have to rewrite it to not use anonymous functions and closures.
