How to write files information to mysql db using php

Hi all .I wonder how i can write the file path and file name that i read from mp3 folder and write them to mysql database table. Currently print_r($playlist); outputs the file names with .mp3 extention as shown below .Furthermore,print_r(htmlentities($code)) output path and file title as shown below. I be happy if an expert show me how i can write the file name and file path and write them to mysql db with file number.Thanks

Code:

<?php

// setting the directory to search for mp3 files
$dir = "mp3/";

// reading the directory and inserting the mp3 files in the playlist array
$n = 0;
$playlist = array();
$fdir = opendir($dir);
while($i = readdir($fdir)) {
  // if a .mp3 string is found, add the file to the array
  if (strpos(strtolower($i),".mp3") !== false) {
            $playlist[$n] = $i;
            $n++;
          }
}
// close the directory and sort the array
closedir($fdir);
array_multisort($playlist);

print_r($playlist);

// echoing the playlist to flash
 $code = "<player showDisplay=\"yes\" showPlaylist=\"no\" autoStart=\"yes\">\n";
 for ($i=0; $i<sizeof($playlist); $i++) {
  // for the title it filters the directory and the .mp3 extension out
    $code .= "  <song path=\"$dir.$playlist[$i]\" title=\"".str_replace(".mp3","",$playlist[$i])."\" />\n";
 }
 $code .= "</player>";

print_r(htmlentities($code));
