check this 

$page_num =">256";
 if(preg_match_all('/\W/', $page_num,$matches))

       print_r($matches);
 }

What you have missed is ending delimiter

$page_num =">256";
 if(preg_match('^[-<>]+$^', $page_num))   
                        ^// this one
 {
    //Here it should returns special chars present in string..
 }

Demo of your code, here

or you can try this,

$string = 'your string here';

if (preg_match('/[\'^£$%&*()}{@#~?><>,|=_+¬-]/', $string))
{
    echo "yes";
} else {
    echo "no";
}

One more solution is

preg_match('![^a-z0-9]!i', $string);
