<body>

<?php

session_start();
if($_SERVER['REQUEST_METHOD'] == "POST"){
$editorData = $_POST[ 'editor1' ];
$fileName = $_POST[ 'tname' ];
$uid= $_SESSION['username'];

$filePath ="../template/".$uid."/";
$myFile = $fileName.".html";

if (!file_exists($filePath)) {
mkdir($filePath, 0755);
}

if (file_exists($filePath.$myFile)) {
$myFile = $fileName."(".$num.")".html";
}



$fh = fopen($filePath.$myFile, 'w') or die("Can not open file");
fwrite($fh, $editorData);
fclose($fh);

echo "You have created a template. You can close this tab now";

}

?>

    You can use glob to find all files matching your filename and the following number, you could then count those files to figure out what the next file should be named.

    Since your first file does not follow the same naming scheme as the following, you have to count that one for it self.

    // Check if a file with the exact name exists
if(file_exists($filePath.$myFile)){
    // It does - the next number should be 1
    $num = 1;
    // Check how many more files with the name followed by a number exists
    $existingFiles = glob($filePath.$fileName.'([0-9]*).html');
    $num += count($existingFiles);
    // Create the new name of the file
    $myFile = $fileName."(".$num.")".html";
}

    Be aware that if you allow deletion of the files, this will not work, as the count of existing files is no longer guaranteed to be equal to the highest number in the list.
