Hello! I need help about fwrite option ,i have this script
and need write everytime that $id , but my problem is when the script have another id delete the first one and rewrite the new one.i need to have old and write the new without rewrite the old $id.Thank you in advance.

if($id = isset($_REQUEST['file']) ? $_GET['file'] : ''){
$myFile = "urls.txt";
$fh = fopen($myFile, 'c') or die("can't open file");
$stringData = $id;
fwrite($fh, $stringData);

} else { echo "You dont put any id <br /> <br />";


Solved it replace "c" with "a+" Thank you
