从Php中的文本文件中选择一个随机单词?

How can I pick a random word from a file of comma-separated words?

$var = file_get_contents('the_file.txt'); //Take the contents from the file to the variable
$result = explode(',',$var); //Split it by ','
echo = $result[array_rand($result)]; //Return a random entry from the array.
echo explode(',',file_get_contents('file.txt'))[rand(0,99)];

That is it in the least amount of code.
