Golf.php

<?php

$array = ['quick', 'fox'];
$string = 'the quick brown fox jumps over the lazy dog';

if(in_array(1,array_map(function($e)use($string){return(strpos($string, $e)!== FALSE)?1:0;},$array))){
  echo "The string contains an element in the array.";
}

You can remove the single quotes around the numbers to reduce some characters

if(in_array(1,array_map(function($e)use($string){return strpos($string,$e)!==false?1:0;},$array)))

You can also guarantee that strpos() !== false will always return a boolean.

if(in_array(true,array_map(function($e)use($string){return strpos($string,$e)!==false;},$array)))

Also PHP now has arrow functions:

if(in_array(true,array_map(($e)=>strpos($string,$e)!==false,$array)))

PHP doesn't have arrow functions, right? Or did I miss anything?

Since when did PHP have arrow functions lmao
