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
