Question

Can anyone give me a solution for the below lines of code:

 $filteredArray = array_filter($wordArray, function ($x) {
    return !preg_match("/^(.|a|an|and|the|this|at|in|or|of|is|for|to|em|com|be
       |with|href|me|rt|by|np|http|www)$/x", $x);
 });

This line not producing any error in my localhost using XAMPP, but the same line is showing an error in my nginx server (online).

What can I do for this. Why this is showing?

Answer 1

Sounds like your server may not be running PHP 5.3 or later, which is needed to support anonymous functions. Instead, you can create the function and pass it as a callback function string to array_filter().

function wordFilter($x) {
  return !preg_match("/^(.|a|an|and|the|this|at|in|or|of|is|for|to|em|com|be
    |with|href|me|rt|by|np|http|www)$/x", $x);
}

$filtered_array = array_filter($wordArray, 'wordFilter');
