preg_grep

  • The preg_grep function in PHP is a useful function to find entries in an array that match a given pattern. Ruby does this same operation with the grep method.

    In this example, we’ll build a new array that only consists of email addresses that end in .com.

    PHP

    $myArray = array('joe@example.com', 'walter@example.org');
$result = preg_grep('/\.com$/', $myArray);
 
var_export($result);
// => array('joe@example.com')

    Ruby

    my_array = ['joe@example.com', 'walter@example.org']
result = my_array.grep(/\.com$/)
 
p result
# => ["joe@example.com"]
