使用正则表达式在数组中查找某个值的最短代码？

Lets say I have an array with these elements:

[
    'whatever',
    'something else',
    'foobar'
]

I know I can iterate over the array and check for foobar using a regex for example. The question is, is there a shorter way of doing that?

Thanks?

<?php

$items = [
    'whatever',
    'something else',
    'foobar'
];

$matches  = preg_grep ('/foobar/', $items);
var_dump($matches);

?>

You don't need to iterate over the array, you can use preg_grep and pass your array instead.

Happy coding

Not regex , but still worth a mention

if(in_array($string,$array)) {
    //is shortest i can think of 
}

OR

$your_var = in_array($string,$array) ? 'this is foo' : 'something else';
