Examples

Example #1 CURLFile::__construct example

Object-oriented style

<?php
/* http://example.com/upload.php:
<?php var_dump($_FILES); ?>
*/

// Create a cURL handle
$ch = curl_init('http://example.com/upload.php');

// Create a CURLFile object
$cfile = new CURLFile('cats.jpg','image/jpeg','test_name');

// Assign POST data
$data = array('test_file' => $cfile);
curl_setopt($ch, CURLOPT_POST,1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);

// Execute the handle
curl_exec($ch);
?>

Procedural style

<?php
/* http://example.com/upload.php:
<?php var_dump($_FILES); ?>
*/

// Create a cURL handle
$ch = curl_init('http://example.com/upload.php');

// Create a CURLFile object
$cfile = curl_file_create('cats.jpg','image/jpeg','test_name');

// Assign POST data
$data = array('test_file' => $cfile);
curl_setopt($ch, CURLOPT_POST,1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);

// Execute the handle
curl_exec($ch);
?>

The above example will output:

array(1) {
  ["test_file"]=>
  array(5) {
    ["name"]=>
    string(9) "test_name"
    ["type"]=>
    string(10) "image/jpeg"
    ["tmp_name"]=>
    string(14) "/tmp/phpPC9Kbx"
    ["error"]=>
    int(0)
    ["size"]=>
    int(46334)
  }
}

    'blob[0]' => new CURLFile(realpath('first-file.jpg'), 'image/jpeg'),
    'blob[1]' => new CURLFile(realpath('second-file.txt'), 'text/plain'),
    'blob[2]' => new CURLFile(realpath('third-file.exe'), 'application/octet-stream'),
