Save image from url with curl PHP

Question

I need to save an image from a url using CURL and save it to a folder on my server. I've been battling with this code to no avail. Ideally I'd like to grab the image and save it as "photo1" or something. Help!

    function GetImageFromUrl($link)      {      $ch = curl_init();      curl_setopt($ch, CURLOPT_POST, 0);      curl_setopt($ch,CURLOPT_URL,$link);      curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);      $result=curl_exec($ch);      curl_close($ch);      return $result;      }      $sourcecode = GetImageFromUrl($iticon);      $savefile = fopen(' /img/uploads/' . $iconfilename, 'w');     fwrite($savefile, $sourcecode);     fclose($savefile); 

Answer 1

try this:

function grab_image($url,$saveto){     $ch = curl_init ($url);     curl_setopt($ch, CURLOPT_HEADER, 0);     curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);     curl_setopt($ch, CURLOPT_BINARYTRANSFER,1);     $raw=curl_exec($ch);     curl_close ($ch);     if(file_exists($saveto)){         unlink($saveto);     }     $fp = fopen($saveto,'x');     fwrite($fp, $raw);     fclose($fp); } 

and ensure that in php.ini allow_url_fopen is enable

Option #1

Instead of picking the binary/raw data into a variable and then writing, you can use CURLOPT_FILE option to directly show a file to the curl for the downloading.

Here is the function:

// takes URL of image and Path for the image as parameter function download_image1($image_url, $image_file){     $fp = fopen ($image_file, 'w+');              // open file handle      $ch = curl_init($image_url);     // curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); // enable if you want     curl_setopt($ch, CURLOPT_FILE, $fp);          // output to file     curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);     curl_setopt($ch, CURLOPT_TIMEOUT, 1000);      // some large value to allow curl to run for a long time     curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0');     // curl_setopt($ch, CURLOPT_VERBOSE, true);   // Enable this line to see debug prints     curl_exec($ch);      curl_close($ch);                              // closing curl handle     fclose($fp);                                  // closing file handle } 

And here is how you should call it:

// test the download function download_image1("http://www.gravatar.com/avatar/10773ae6687b55736e171c038b4228d2", "local_image1.jpg"); 

Option #2

Now, If you want to download a very large file, that case above function may not become handy. You can use the below function this time for handling a big file. Also, you can print progress(in % or in any other format) if you want. Below function is implemented using a callback function that writes a chunk of data in to the file in to the progress of downloading.

// takes URL of image and Path for the image as parameter function download_image2($image_url){     $ch = curl_init($image_url);     // curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); // enable if you want     curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);     curl_setopt($ch, CURLOPT_TIMEOUT, 1000);      // some large value to allow curl to run for a long time     curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0');     curl_setopt($ch, CURLOPT_WRITEFUNCTION, "curl_callback");     // curl_setopt($ch, CURLOPT_VERBOSE, true);   // Enable this line to see debug prints     curl_exec($ch);      curl_close($ch);                              // closing curl handle }  /** callback function for curl */ function curl_callback($ch, $bytes){     global $fp;     $len = fwrite($fp, $bytes);     // if you want, you can use any progress printing here     return $len; } 

And here is how to call this function:

// test the download function $image_file = "local_image2.jpg"; $fp = fopen ($image_file, 'w+');              // open file handle download_image2("http://www.gravatar.com/avatar/10773ae6687b55736e171c038b4228d2"); fclose($fp);                                  // closing file handle
