Hi E's, I have a line of code that work with a real number, but don't word with the name of variable.
The line is this one, and in this way work well:
====================================
$keysrel_numeracao = array_filter(array_values($keysrel_numeracao),create_function('$item','return $item>=11;'));
====================================

The problem is, I want substitute the real number (11) to a name of variable ($number), and the script don't work, like:
====================================
$number = 11;
$keysrel_numeracao = array_filter(array_values($keysrel_numeracao),create_function('$item','return $item>=$number;'));
====================================
The script don't work, and don't give me any error.

My question is, what is the correct way to change the number 11 to the variable $number?

Regards, JC

You have two options: either define the variable as a global within the function, or resolve the variable before the function is created:
# define as global
$number = 11;
$keysrel_numeracao = array_filter(array_values($keysrel_numeracao),
  create_function('$item','global $number; return $item>=$number;'));
 
# variable resolved before function is created 
$number = 11;
$keysrel_numeracao = array_filter(array_values($keysrel_numeracao),
  create_function('$item','return $item>='.$number.';'));
