PHP：从字符串剪切方向

Question

我的字符串如下：

 /home/kamal/public_html/clients/book/wp-content/uploads/wpcf7_uploads/1983322598/k.jpg 

我只需要

wp-content/uploads/wpcf7_uploads/1983322598/k.jpg 

怎么做？

Answer 1

$string = "/home/kamal/public_html/clients/book/wp-content/uploads/wpcf7_uploads/1983322598/k.jpg";

$exploded_string = explode("/", $string);
//$exploded_string is now an array of: home, kamal, public_html.... ...k.jpg

$n = array_search("wp-content", $exploded_string);
//$n is now the index of "wp-content" in the $exploded_string array

$new_path = array_slice($exploded_string, $n);
$new_path = implode("/", $new_path);

echo $new_path;
