PHP，从绝对路径中查找相对路径的最简单方法

Question

let's say i have an absolute path : /myproject/web/uploads/myfolder/myfile.jpg

i'm searching to determinate a relative path fom a part of the absolute path, like this:

<?php

echo relative_path('/myproject/web/uploads/myfolder/myfile.jpg', 'web/uploads');

// print "myfolder/myfile.jpg"

Answer 1

If I understand, you just want the part from the absolute path that is after the given part:

function relative_path($absolute, $part) {
    $pos = strpos($absolute, $part);
    return substr($absolute, $pos + strlen($part) + 1);
}
