I'm trying to use array_walk with an anonymous function, but I always get the error 

 // Parse error: syntax error, unexpected T_FUNCTION in ... on line X
 if(!empty($myArray)) {
   array_walk($myArray, function(&$value, $key){ // Line X
     $value = '"'.$value.'"'; // Add quotes
   });
 }

The surrounding file syntax is correct. Any thoughts?

What version of PHP are you using? – Jon Cram Jul 7 '10 at 18:49

Yes, true anonymous functions (closures) are only available from PHP 5.3, however you can still create an anonymous function in earlier versions of PHP using the create_function() call, which can be used with array_walk(). Something like:

array_walk($myArray, create_function('&$value,$key', '$value = \'"\'.$value.\'"\';'));

Check your PHP version... Anonymous functions are only available since 5.3...

Oh, I had no idea this was a version issue. Thanks! – ash Jul 7 '10 at 18:52
