I solved own question with this code:

<?php
function show_degree($str,$deg) {
    $deg=""+$deg;
    echo '<script type="text/javascript">alert("' . $str .$deg. '")</script>';
}

$given_number="90222179";

$myfile = fopen("degree/dm.txt", "r");
while (($line = fgets($myfile)) !== false) {
    list($number, $degree) = explode("\t", $line);
    if($number==$given_number) {
        echo $degree;
        show_degree(   "Hello\
\
Your Degree:\
",$degree  ); 
        }   
    } 
    fclose($myfile);
?>
