如何使用php中的file_put_content从不同的路径（不是服务器默认路径）打开文件

Is there any way to file_put_contents from different path i mean instead of

c/programfiles/../../htdocs/test.txt using c/test/test.txt

the below is the code i am using:

$date=current_date;

$file = "test_"$date".txt";

$contents = "testtest";

file_put_contents($file, $contents);

Many thanks in advance!

When placing files on your computer you can either use relative or absolute path like this:

// absolute path
$file = "C:/temp/test.txt";

// relative path from C:/Program Files/wamp/htdocs/index.php
$file = "../../temp/test.txt";

Both of those files point to the same place
