Php在链接中获取图像名称

Question

i am using a script, to get the first image, inside a post.

Here is the script.

$first_img = '';
                $my1content = $row['post_content'];
                $output = preg_match_all('/<img.+src=[\'"]([^\'"]+)[\'"].*>/i', $my1content, $matches); 
                $first_img = $matches [1] [0];
                if(empty($first_img)){ //Defines a default image
                $first_img = "/img/default.png";
                }

This script echo the full image link, for example: http://mywebsite.com/images/thisistheimage.jpg

is possible to divide the image link , image name , and image extenction so i need to get 3 results

the link, example:http://mywebsite.com/images/ the image name, example: thisistheimage the image extenction, example: .jpg

Please let me know if its all clear, thanks for reading.

<?php
  $image_name       = pathinfo( $first_img, PATHINFO_FILENAME );
  $image_extension  = pathinfo( $first_img, PATHINFO_EXTENSION );
  $image_with_extension = basename( $first_img );
  $image_directory      = dirname( $first_img );
?>
