问题描述
我目前正在使用下面的代码尝试从random.txt
中读取一条随机行,并将其作为$data
传递,但是返回为空.每个字符串都有自己的行,我在这里错过了什么吗?这不行吗?如果没有,如何从文本文件中获取随机行并将其用作我的$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;
