Collect remote images in php articles to local_PHP tutorial

$message //Article content

//Regular (this is not yet)

$reg = "/]*src="(http://(.+)/(.+).(jpg|gif|bmp|bnp))"/isU";

//Store the extracted img address into $img_array variable

preg_match_all($reg, $message, $img_array, PREG_PATTERN_ORDER);

//Filter duplicate images

$img_array = array_unique($img_array[1]);Copy the code

Step 2. Loop the $img_array array. Save the image and replace the article position

foreach ($img_array as $img){

 // Determine whether the picture is on your own website

if('xxx.com' != get_domain($img)){// If this picture is not on your own server

                                                                   

 $Gimg = new GetImage();

$Gimg->source = $img;   

$Gimg->save_to = './data/temp/';   

$FILE = $Gimg->download( ; = pic_save(

$FILE

,0, ''); //Text path replacement $message = str_replace

($img

, $img_path, $message );                                                                                  At this time, the image in $message has been replaced with the local address of your server , and the image is also saved to your server . Copy the code //The following

//Get the
