php regex not working while working on regex101

Here is my code. I am trying to match this string with my regex but it fails everytime on my local xampp server and my dedicated server. Surprsingly when i test this on regex101 it works there somehow. Why ??

<?php

$str = "80 ×× ×× ×× ×× ××
×× ×× 91 94 ×× ××
";

echo strlen($str);

if (preg_match("/[0-9*+=\-#@×?]{2,3}[ \[\]().]{1,3}[0-9*+=\-#@×?]{2,3}[ \[\]().]{1,3}[0-9*+=\-#@×?]{2,3}[ \[\]().]{1,3}[0-9*+=\-#@×?]{2,3}[ \[\]().]{1,3}[0-9*+=\-#@×?]{2,3}/", $str)) {
    echo "ok";
}else{
    echo "no mto";
}

?>

You need to use the u modifier to enable the unicode mode for regular expressions, since that × character in subject and pattern is not within the ASCII character range. Note the trailing /u in the pattern definition: 

<?php

$str = <<<EOT

80 ×× ×× ×× ×× ××
×× ×× 91 94 ×× ××

EOT;

if (preg_match("/[0-9*+=\-#@×?]{2,3}[ \[\]().]{1,3}[0-9*+=\-#@×?]{2,3}[ \[\]().]{1,3}[0-9*+=\-#@×?]{2,3}[ \[\]().]{1,3}[0-9*+=\-#@×?]{2,3}[ \[\]().]{1,3}[0-9*+=\-#@×?]{2,3}/u", $str)) {
    echo "ok";
} else {
    echo "no mto";
}

The output obviously is: 

ok
