• How to find a string in an array in PHP? 6 answers

If I have an array that contains some strings like so

$roleNames = ['sales_agent', 'admin'];

And I want to check if that array contains the string 'sales_agent', what would be the best way to go about this with PHP?

Ideally I would like to have the check return a boolean value.

Easiest Way

$word='admin';
$array = array('sales_agent', 'admin');

if (in_array($word, $array)) {
    echo "admin is in array";
}
