PHP will match the remote image address in the article and download the image to local _php tips

Using the regular expression of PHP to implement:

$content = ' Here is the content of the article, insert here a picture test  ';
$content = Stripslashes ($content);
$img _array = Array ();
Match all remote pictures
Preg_match_all ("/(src| SRC) =["| ' |] {0,} (http://(. *). (gif|jpg|jpeg|bmp|png)) /isu ", $content, $img _array);
$img _array = array_unique ($img _array [2]) that match out the non-duplicate picture;
Print_r ($img _array);

It matches the remote picture, and we need to keep it local. Here are two points to note:
