如何将不带扩展名的文件从远程URL（应用程序的Google Play商店映像）复制到PHP中的服务器的临时文件夹？

Question

I am working on application of scraping structured data from Google Playstore and saving it in the database. I am getting all the structured data. I am trying to copy the itemprop="image" url and save the image to my server.

I have tried many things but nothing works as the file doesn't have an extension. The code below works but the either invalid file is generated or a file with zero bytes is created.

Sample url that I am trying to copy

PHP code that I am using

function getimg($url) {         
    $headers[] = 'Accept: image/gif, image/x-bitmap, image/jpeg, image/pjpeg';              
    $headers[] = 'Connection: Keep-Alive';         
    $headers[] = 'Content-type: application/x-www-form-urlencoded;charset=UTF-8';         
    $user_agent = 'php';         
    $process = curl_init($url);         
    curl_setopt($process, CURLOPT_HTTPHEADER, $headers);         
    curl_setopt($process, CURLOPT_HEADER, 0);         
    curl_setopt($process, CURLOPT_USERAGENT, $useragent);         
    curl_setopt($process, CURLOPT_TIMEOUT, 30);         
    curl_setopt($process, CURLOPT_RETURNTRANSFER, 1);         
    curl_setopt($process, CURLOPT_FOLLOWLOCATION, 1);   
    curl_setopt($process, CURLOPT_SSL_VERIFYPEER,false);    
    // curl_setopt($process, CURLOPT_SSL_VERIFYPEER,0); 
    $return = curl_exec($process);         
    curl_close($process);         
    return $return;     
}

$upload_dir = wp_upload_dir();
$length= strlen($image);
$new_string = substr($image,0,$length-8);
$imagename= basename($new_string);
$image2 = getimg($imgurl); 
$new_image_path = file_put_contents($upload_dir['basedir'].'/custom-temp/'.$imagename,$image2); 

Answer 1

There are several errors in your code such as the $useragent not being named consistently and $imgurl being undefined. Consider turning on errors in PHP when you are debugging so that you can catch these.

I can get your code to work like this (just change the path back to wp_upload_dir() ):

function getimg($url) {         
    $headers[] = 'Accept: image/gif, image/x-bitmap, image/jpeg, image/pjpeg';              
    $headers[] = 'Connection: Keep-Alive';         
    $headers[] = 'Content-type: application/x-www-form-urlencoded;charset=UTF-8';         
    $gim = 'php';         
    $process = curl_init($url);         
    curl_setopt($process, CURLOPT_HTTPHEADER, $headers);         
    curl_setopt($process, CURLOPT_HEADER, 0);         
    // curl_setopt($process, CURLOPT_USERAGENT, $useragent);         
    curl_setopt($process, CURLOPT_TIMEOUT, 30);         
    curl_setopt($process, CURLOPT_RETURNTRANSFER, 1);         
    curl_setopt($process, CURLOPT_FOLLOWLOCATION, 1);   
    curl_setopt($process, CURLOPT_SSL_VERIFYPEER,false);    
    // curl_setopt($process, CURLOPT_SSL_VERIFYPEER,0); 
    $return = curl_exec($process);
    curl_close($process);         
    return $return;     
}

$upload_dir = "/home/laurent/test/upload";
$length= strlen($image);
$new_string = substr($image,0,$length-8);
$imagename= basename($new_string);
$image2 = getimg($image); 
$new_image_path = file_put_contents($upload_dir.'/'.$imagename,$image2);
