从字符串PHP中删除尾随斜杠

Question

是否可以使用PHP从字符串中删除尾部斜杠/ ？

Answer 1

Sure it is, simply check if the last character is a slash and then nuke that one.

if(substr($string, -1) == '/') {
    $string = substr($string, 0, -1);
}

Another (probably better) option would be using rtrim() - this one removes all trailing slashes:

$string = rtrim($string, '/');

Answer 2

这会删除尾部斜杠：

$str = rtrim($str, '/');

Answer 3

Long accepted, however in my related searches I stumbled here, and am adding for "completeness"; rtrim() is great, however implemented like this:

$string = rtrim($string, '/\\'); //strip both forward and back slashes

It ensures portability from *nix to Windows , as I assume this question pertains to dealing with paths.

Answer 4

rtrim使用rtrim导致它尊重字符串并不以尾部斜杠结束

Answer 5

Yes, it is!
