Filter a set of bad words out of a PHP array

Question

I have a PHP array of about 20,000 names, I need to filter through it and remove any name that has the word job, freelance, or project

Answer 1

I'd be inclined to use the array_filter function and change the regex to not match on word boundaries

$data1 = array('Phillyfreelance' , 'PhillyWebJobs', 'web2project', 'cleanname');

$cleanArray = array_filter($data1, function($w) { 
     return !preg_match('~(freelance|project|job)~i', $w); 
});
