Using CURL within a loop to download a file, 1st one works, 2nd one times out

[kitenski]

Morning all,

 

I am using CURL to download an image file within a loop. The first time it runs fine and I see the image appear in the directory.

 

The second time it fails with a timeout, despite it being a valid URL.

 

Can anyone suggest why it always fails on the 2nd time and how to fix it?

 

The snippet of code is:

 

// download image 

$extension = "gif"; 
$ch = curl_init(); 
curl_setopt($ch, CURLOPT_TIMEOUT, 90); 
curl_setopt($ch, CURLOPT_URL, $imgurl); 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); 
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true); 
echo $imgurl . " attempting to open URL "; 
$i = curl_exec($ch); 
if ( $i==false ) { 
  echo curl_errno($ch).' '.curl_error($ch); 
} 
$image_name=time().'.'.$extension; 
$f = fopen('/fulldirectorypath/' . $image_name ,'w+'); 
fwrite($f,$i); 
fclose($f); 

 

I have put an echo in there to display the $IMGURL, to check it is valid, and upped the timeout to 90 secs, but it still fails.  I have also added a 240 sec sleep within the loop, but I still get the same error.

This is what I see on screen:

 

http://images.eu-xmedia.de/thumbnails/34555861/5676051/pt=pic,lang=2,origfile=yes/image.gif attempting to open URL 28 Operation timed out after 90 seconds with 0 bytes received

 

an empty file is created in my directory.

 

thanks alot,
