You can't use $pera inside the method like that because it's not defined inside the method scope.

If you want to use the method, pass it as a parameter.

function provera($prom, $pera){ //passed as a param
    if (preg_match("/[0-9\,\.\?\>\.<\"\'\:\;\[\]\}\{\/\!\\\@\#\$\%\^\&\*\(\)\-    \_\=\+\`[:space:]]/",$prom)){
        echo "Nepravilan unos imena ili prezimina!";
    echo $pera;
}
