Calculate the relative path of two paths using PHP_PHP Tutorial

Copy code The code is as follows:

function relativePath($aPath, $bPath) {
                                                                                                                                                                                                                                                                         Split the string
$bArr = explode('/', $bPath);
$aDiffToB = array_diff_assoc($aArr, $bArr); //array_diff_assoc() is used to get the difference between array A and array B For the difference set of elements, if both Key and Value are different, they are regarded as different elements. Here, the elements in the A array that are different from the B array are returned. PATH = '';
for ($ i = 0; $ i & lt; $ Count -1; $ i ++) {
$ PATH. = '../';

                 $path .= implode('/', $aDiffToB); // implode() is used to connect the array elements using the specified string, here returns the string after connecting the array elements with '/'

return $path;
}

echo relativePath('/a/b/c/d/a.php', '/a/b/1/2/b.php');
