将数组保存到文件 - 仅限值

Question

我正在使用这种方法：

$s = array("one","two","three");
file_put_contents('file.txt', print_r($s, true)."\n");

file.txt输出为：

Array
(
    [0] => one
    [1] => two
    [2] => three
)

我希望输出只是这样的值：

one
two
three

怎么可以这样做？

Answer 1

试试这个

$s = array("one","two","three");
file_put_contents('file.txt', implode("\n",$s));
