I copied an article and found that the image paths are from other websites. how can I download these images to a local directory with one click and change them to a local path.

 
 
 
  
  
 
   
 
    
The code is as follows:
 
    
 
 
   
 
   
 
    
/*** Get the path of the image in the replacement article * @ param string $ xstr content collection webpage content * @ param string $ the file name of the photo created by keyword I wrote upimg * @ param string $ oriweb generally, the URL is null * @ return string **/function replaceimg ($ xstr, $ keyword, $ oriweb) {$ basedir = dirname (_ FILE _); // save path $ d = date ('ym', time ()); $ dirslsitss = $ basedir. '/.. /uploads /'. $ keyword. '/'. $ d; // whether the category exists if (! Is_dir ($ dirslsitss) {@ mkdir ($ dirslsitss, 0777);} // src preg_match_all ('#] *> # I', $ xstr, $ match); foreach ($ match [1] as $ imgurl) {$ imgurl = $ imgurl; if (is_int (strpos ($ imgurl, 'http '))) {$ arcurl = $ imgurl;} else {$ arcurl = $ oriweb. $ imgurl;} $ img = file_get_contents ($ arcurl); if (! Empty ($ img) {// save the image to the server $ fileimgname = time (). "-". rand (1000,9999 ). ". jpg "; $ filecachs = $ dirslsitss. "/". $ fileimgname; $ fanhuistr = file_put_contents ($ filecachs, $ img); $ saveimgfile = "/uploads/$ keyword ". "/". $ d. "/". $ fileimgname; $ xstr = str_replace ($ imgurl, $ saveimgfile, $ xstr) ;}return $ xstr ;}
