PHP Menghilangkan Simbol atau Tanda Tidak Perlu Untuk Membuat URL

Misalkan ingin membuat kata url dari kalimat berikut $name = nama&^%$#@*() saya Nanang

$strtolower = str_replace(' ', '-', $name);
$perm=str_replace(' ','-',strtolower($name));
$perm = str_replace('(','',$perm);
$perm = str_replace(')','',$perm);
$perm = str_replace('.','',$perm);
$perm = str_replace('&','',$perm);
$perm = str_replace('[','',$perm);
$perm = str_replace(']','',$perm);
$perm = str_replace(',','',$perm);
$perm = str_replace('/','',$perm);
$perm = str_replace('"','',$perm);
$perm = str_replace('---','-',$perm);
$perm = str_replace('?','',$perm);
$perm = str_replace('|','',$perm);
$perm = str_replace('@','',$perm);
$perm = str_replace('#','',$perm);
$perm = str_replace('%','',$perm);
$perm = str_replace('^','',$perm);
$perm = str_replace('&','',$perm);
$perm = str_replace('*','',$perm);
$perm = str_replace('.','',$perm);
$perm = str_replace('!','',$perm);
$perm = str_replace('39;','',$perm);
$perm = str_replace('_','',$perm);

Maka hasil $perm nya adalah nama saya Nanang
