從Php中的文本文件中選擇一個單詞？

Question

如何從逗號分隔的文字中挑選一個隨機單詞？

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)]; 

即它的代碼量最少。
