PHP文件不写入当前目录？ [英] PHP file doesn't write to current directory?

问题描述

我有一个网络的主机是一个PHP文件如下：

I have a PHP file on a web-host that is as follows:

<?php

file_put_contents('test.txt','TEST');    
echo 'OK';

?>

但文件的test.txt 当我从浏览器中执行该页面未创建。为什么不呢？它是一个权限问题？

But the file test.txt is not created when I execute the page from a browser. Why not? Is it a permissions issue?

推荐答案

是PHP的医生说。

如果文件名不存在，则创建该文件。否则，现有文件被覆盖，除非FILE_APPEND标志被设置

If filename does not exist, the file is created. Otherwise, the existing file is overwritten, unless the FILE_APPEND flag is set.

这只是如果你写有该文件夹的权限....尝试

That is only if you write have permission on that folder .... try

error_reporting(E_ALL);
ini_set("display_errors", "on");

if (! is_writable(__DIR__)) {
    trigger_error("I don't have permission");
}

file_put_contents('test.txt', 'TEST');
