从 TXT 文件中提取随机行作为字符串

问题描述

我目前正在使用下面的代码尝试从 random.txt 中读取随机行并将其作为 $data 传递，但它返回空.每个字符串都有自己的行，我在这里遗漏了什么吗?这不应该工作吗?如果不是，我如何从我的文本文件中获取随机行并将其用作我的 $data 字符串?

I'm currently using the code below to try and read a random line from random.txt and pass it as $data, however it comes back empty. Each string has its own line, am I missing something here? Shouldn't this work? If not how can I get a random line from my text file and use it as my $data string?

$f_contents = file("random.txt");
$line = $f_contents[array_rand($f_contents)];
$data = $line;

已解决 - 错误的 CHMOD以为我已经仔细检查过了，很抱歉提出问题.

Solved - Bad CHMOD Thought I had double checked it, sorry to post a question.

推荐答案

确保您的文件设置了读取权限，应该 CHMOD 为 644 或 744.

Make sure your file has read permissions set, should be CHMOD'd to 644 or 744.
