Saves broken jpg, news parsing script, what's wrong?

Question

PHP

The script parses the news, downloads the image from the link, saves the broken file to the server, what's wrong? :
if($f_Link){
$c=file_get_contents($f_Link);
$fh=fopen($_SERVER['DOCUMENT_ROOT']."/scripts/news.txt","w");
fwrite($fh,$c);
fclose($fh);
preg_match("/b-material-head__title\">(.{1,})<\/h1>/", $c, $h1);
preg_match("/class=\"b-material-head__date-day\ ">(.{10})<\/span>/", $c, $date);
preg_match("/link rel=\"image_src\" href=\"(.*)\">/U", $c, $img); -save image
preg_match("/(\C*<\/article>)/U", $c, $text);
$id=mysql_insert_id($LinkID);
if($img[1 ]){
$ext= strrchr($img[1],
mysql_unbuffered_query("INSERT INTO Message5 (User_ID,Subdivision_ID,Sub_Class_ID,Priority,Checked,Created,parent_class_id,parent_mess_id,foto) VALUES(1,'19','19',20,1,NOW(),'2',' ".$message."','str".$ext.":image/jpeg:1');", $LinkID);
$id=mysql_insert_id($LinkID);
copy($img[1],$_SERVER['DOCUMENT_ROOT']."/sysfiles/45_".$id.$ext);
}
}

is
a mini-picture, only it is in the body of the news, but should be at the top in the headline.
The script used to work without problems, the layout on the Russian newspaper website was updated, I am correcting regular expressions and I can’t solve the problem with the image in any way. Maybe someone sees the error?

Answer 1

Goodnight.
The problem is in the line:
$img['1'] contains '//cdnimg.rg.ru/img/content/138/31/30/pr_t_650x433.jpg'.
Try doing this:
The file will copy without problems.
And do checks so that you can determine the error yourself.
Do the same as you do now:

if(!copy($img[1],$_SERVER['DOCUMENT_ROOT']."/sysfiles/45_".$id.$ext)){
   echo 'error';
}
else{
 echo 'success';
}

Without specifying the data transfer protocol, there should be a warning, add https and everything should work.
And look at the server logs, there should be this warning.
And the regular expression pattern itself can be tweaked.
ps
And in line
there is no saving/copying the image)
ps
This code

$fh=fopen($_SERVER['DOCUMENT_ROOT']."/scripts/news.txt","w");
fwrite($fh,$c);
fclose($fh);

can be replaced with file_put_contents()
