Append to file…will I need to lock
User1684072’s Questions:
Php newbie here
I am creating a webpage that stores some information in a text file by appending to it.
Everytime the webpage loads, there is a small php script that adds information to the end of the text file. I am using file_put_contents. Here is VERY simplified version of my code:
<?php
$file = "records.txt";
$current = file_get_contents($file);
$current .= "id = ". $_GET["id"]." n";
file_put_contents($file, $current );
?>
Here is my concern…if hundreds of people open my webpage, will my script be able to capture ALL the user information without missing anyone. This is extremely important.
I am afraid to lock it(use LOCK_EX) because that would mean that when a new user opens up the webpage the script would not be able to open up and append to the text file if another user is writing to it and thus I would not be able to capture his information which is a BIG problem.
So should I ignore lock or is one needed?? How should I solve this problem
Thanks a lot.
Use fopen() with a switch. This will handle all the problems.
$handle = fopen("somefile.txt", "a");
For your requirements you should not lock the file, but this will probably expose the file to vulnerabilities. So I will suggest an alternative instead.
Instead of a file, insert the information you want on the database.
