Pull random line from TXT file as string
提问by Ryan Cooper
I'm currently using the code below to try and read a random line from random.txtand 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 $datastring?
我目前正在使用下面的代码尝试从中读取随机行random.txt并将其作为 传递$data，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，我怎样才能从我的文本文件中随机获取一行并将其用作我的$data字符串？
$f_contents = file("random.txt");
$line = $f_contents[array_rand($f_contents)];
$data = $line;
Solved - Bad CHMODThought I had double checked it, sorry to post a question.
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。

Make sure your file has read permissions set, should be CHMOD'd to 644 or 744.
确保您的文件设置了读取权限，应该 CHMOD 为 644 或 744。

Your code looks correct, but you can try it this way too:
您的代码看起来是正确的，但您也可以这样尝试：
<?php
$f_contents = file("random.txt");
$line = $f_contents[rand(0, count($f_contents) - 1)];
?>
