使用php创建txt文件失败

Question

I am trying to create a file and write a message in a folder called debug:

 function debug($report){
   $file="/debug/debug.txt";
   file_put_contents($file,$report,FILE_APPEND | LOCK_EX);
 }

The debug folder is in my root directory. But file fails to be created.. Why?

Answer 1

This code will open all the permissions for the folder.

chmod('PATH_TO_FOLDER',0777);

Depending on what exactly you want to do with that folder, you might consider giving it slightly more limited permissions that allow only specific users to read/write to it.

Here are some other examples taken from the PHP manual - http://php.net/manual/en/function.chmod.php

<?php
// Read and write for owner, nothing for everybody else
chmod("/somedir/somefile", 0600);

// Read and write for owner, read for everybody else
chmod("/somedir/somefile", 0644);

// Everything for owner, read and execute for others
chmod("/somedir/somefile", 0755);

// Everything for owner, read and execute for owner's group
chmod("/somedir/somefile", 0750);
?>
