Transfer files between high and low versions of curl

In the past few days, I have to transfer files because I need to call the java interface. I chose curl to transfer files. One pitfall here is that I used the original @ followed by the absolute path of the file directly when transferring files.

However, there was no error, but it felt like it was never sent. Later, I tried it under win, and a warning was thrown directly saying that this method is outdated, please use the curlfile function instead. Only now did I realize that my computer had never turned on the warning and reported errors, but I had always turned it on under win. I had been struggling with this problem for some time.

Let’s look at the code below to see how curl transfers files and array data,

  $beforePath = '/Applications/MAMP/htdocs/photo/1.jpg'; 
        $afterPath = '/Applications/MAMP/htdocs/photo/2.jpg';//绝对路径
        $data = [
                
                'top' => curl_file_create($beforePath),
                'after' => curl_file_create($afterPath),
                'partnerId' => $data['0']['uid'],
                'mobile' => $data1['0']['phone'],
                'email' => $data1['0']['email'],
                'realName' => $data['0']['real_name'],
                
        ];
        curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE); //禁用证书
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
        curl_setopt($ch, CURLOPT_HEADER, false);            
        curl_setopt($ch, CURLOPT_POST, true);  
        curl_setopt($ch,CURLOPT_BINARYTRANSFER,true);
        curl_setopt($ch, CURLOPT_POSTFIELDS,$data);
        curl_setopt($ch, CURLOPT_URL, $url);
        $info= curl_exec($ch);
        curl_close($ch);

The above introduces the high and low versions of curl to transfer files, including the content. I hope it will be helpful to friends who are interested in PHP tutorials.
