从Php中的文本文件中选择一个随机单词？

Question

如何从逗号分隔的单词文件中选择一个随机单词？

Answer 1

$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.

Answer 2

echo explode(',',file_get_contents('file.txt'))[rand(0,99)];

这是代码量最少的。
