Parse error: syntax error, unexpected T_FUNCTION

[kektex]

Just from searching the board I realize this has been asked sooo many times, but I can't seem to locate the problem in this code:

 

usort($status, function($a, $b) {global $sort; return strcmp($a[$sort], $b[$sort]); });

foreach(array_merge(array($cols), $status) as $line)
    call_user_func_array('printf', array_merge(array($fmt), $line));
print_r($print);

 

I'm getting a  " Parse error: syntax error, unexpected T_FUNCTION in ui.php " on the first line of this script.

 

The weird thing is that when I run the script on my PC using EasyPHP I don't get the error, it only happens on my Linux server.

 

Any ideas?

 

Thanks!

Anonymous functions are only available in PHP 5.3.0+. Use create_function.

Hi Alex, Thanks for your help . How can I use create_function to solve this problem? Im not  very knowledgeable in PHP , I am just trying to fix an error in an existing script.

kektex, click here - create_function

Anonymous functions are defined by the arguement string, then the code string.

The syntax would look like this

$func_name = create_function(args_string, code_string);

 

An example could be..

$myvariable = '1';
$myfunction = create_function('$myvariable', '$myvariable * 2');

echo $myfunction;

The result should be 2

 

Here is an example using usort().

$function = create_function('$a, $b', 'return(strlen($a) - strlen($b));');
$array = array('a massive string', 'it', 'huge length', 'cat poop');
usort($array, $function);
print_r($array);

 

I'm not saying this will work or not, but it's an example. I hope you understand!

$lambda is undefined.
