Multiple file upload using php Curl

Question

I'm trying to upload multiple images using the CurlFile function. This is the array i'm passing to the curl function:

array (size=16)
  'action' => string 'saveM' (length=12)
  'firstName' => string 'qwer' (length=4)
  'lastName' => string '' (length=0)
  'gender' => string 'male' (length=4)
  'dateOfBirth' => string '' (length=0)
  'dateOfDeath' => string '' (length=0)
  'type' => string 'family' (length=6)
  'biography' => string 'wqer' (length=4)
  'graveLat' => string '' (length=0)
  'graveLong' => string '' (length=0)
  'communityId' => string '' (length=0)
  'members' => string '' (length=0)
  'privacy' => string 'public' (length=6)
  'token' => string 'a31818ff1f18f1d318fe6' (length=22)
  'image' => 
    object(CURLFile)[35]
      public 'name' => string 'D:\xampp\tmp\phpC6BD.tmp' (length=24)
      public 'mime' => string '' (length=0)
      public 'postname' => string 'head-659652_640.png' (length=19)
  'photos' => 
    array (size=4)
      0 => 
        object(CURLFile)[36]
          public 'name' => string 'D:\xampp\tmp\phpC6CE.tmp' (length=24)
          public 'mime' => string '' (length=0)
          public 'postname' => string '2584150-1486688827928-funnyprofile.jpg' (length=38)
      1 => 
        object(CURLFile)[37]
          public 'name' => string 'D:\xampp\tmp\phpC6CF.tmp' (length=24)
          public 'mime' => string '' (length=0)
          public 'postname' => string '5993755201548256265.jpg' (length=23)
      2 => 
        object(CURLFile)[38]
          public 'name' => string 'D:\xampp\tmp\phpC6D0.tmp' (length=24)
          public 'mime' => string '' (length=0)
          public 'postname' => string 'dummy-image1.jpg' (length=16)
      3 => 
        object(CURLFile)[39]
          public 'name' => string 'D:\xampp\tmp\phpC6E0.tmp' (length=24)
          public 'mime' => string '' (length=0)
          public 'postname' => string 'head-659652_640.png' (length=19)

and this is the curl function:

$curl = curl_init();
            curl_setopt_array($curl, array(
                CURLOPT_RETURNTRANSFER => 1,
                CURLOPT_URL => self::$api_url,
                CURLOPT_POST => 1,
                CURLOPT_POSTFIELDS => ($apicall)
            ));

            $result = curl_exec($curl);
            curl_close($curl);

The image array uploads the files correctly, however my issue lies with the photos multiple images not uploading at all and give an error "Array to string conversion"

Any ideas?

I managed to fix it by changing the out of the photos to be like this:

'photos[0]' => 
        object(CURLFile)[36]
          public 'name' => string 'D:\xampp\tmp\phpC6CE.tmp' (length=24)
          public 'mime' => string '' (length=0)
          public 'postname' => string '2584150-1486688827928-funnyprofile.jpg' (length=38)
'photos[1]' => 
        object(CURLFile)[37]
          public 'name' => string 'D:\xampp\tmp\phpC6CF.tmp' (length=24)
          public 'mime' => string '' (length=0)
          public 'postname' => string '5993755201548256265.jpg' (length=23)
'photos[2]' => 
        object(CURLFile)[38]
          public 'name' => string 'D:\xampp\tmp\phpC6D0.tmp' (length=24)
          public 'mime' => string '' (length=0)
          public 'postname' => string 'dummy-image1.jpg' (length=16)
'photos[3]' => 
        object(CURLFile)[39]
          public 'name' => string 'D:\xampp\tmp\phpC6E0.tmp' (length=24)
          public 'mime' => string '' (length=0)
          public 'postname' => string 'head-659652_640.png' (length=19)
