When I append line to file in php, the previous lines have been deleted, how do I prevent this?

Basically, I just want to add a line to a text file, but when I do it it deletes the previous content of the file.

How can I add a line to a text file without deleting the previous content?

<?php

    $template = $_POST["template"];

    $templateFile = fopen("templates.txt", "a");
    file_put_contents("templates.txt", $template);
    fclose($templateFile);
    //header function to go back to my original page where the form was

?>

You are mixing c style fopen fwrite and fclose with PHP specific file_put_contents function. You have to choose one.

Using the first method you have to fopen the file, specifying name, and mode, writing on the file using fwrite, and closing the file with fclose.

Alternatively you can use the PHP file_put_contents (implementation, documentation), and as you can see the function itself checks that the file is a regular file, that is not locked by another application, writes the content, and close the file.

TL;DR To append to a file in PHP use the following code: 

file_put_contents("myfile.txt", "content", FILE_APPEND);

Remember that writing postdata to a file is not secure!

You don't need to open the file with fopen() if you use file_put_contents(), it already does that for you:

This function is identical to calling fopen(), fwrite() and fclose() successively to write data to a file.

Also you want to set the flag FILE_APPEND, so you append your content, e.g.

file_put_contents("templates.txt", $template, FILE_APPEND);
