如何在字符串中删除两个相同和随机的字符 - PHP

Question

Need to remove random aa/ or bb/ to zz/ letters (with slash) to get /logo/picture.png

$url = "/logo/aa/picture.png";
$url = "/logo/bb/picture.png";
$url = "/logo/cc/picture.png";

Answer 1

This is an alternative which doesn't care what's contained in that url part or what lengths url parts have:

$urlParts = explode('/', $url);
array_splice($urlParts, count($urlParts) - 2, 1);
$url = implode('/',  $urlParts);
