There are "@" issue on multipart POST requests.
Solution for PHP 5.5 or later:
- Enable CURLOPT_SAFE_UPLOAD.
- Use CURLFile instead of "@".
Solution for PHP 5.4 or earlier:
- Build up multipart content body by youself.
- Change "Content-Type" header by yourself.
The following snippet will help you :D
<?php
/**
* For safe multipart POST request for PHP5.3 ~ PHP 5.4.
*
* @param resource $ch cURL resource
* @param array $assoc "name => value"
* @param array $files "name => path"
* @return bool
*/
function curl_custom_postfields($ch, array $assoc = array(), array $files = array()) {
// invalid characters for "name" and "filename"
static $disallow = array("\0", "\"", "\r", "\n");
// build normal parameters
foreach ($assoc as $k => $v) {
$k = str_replace($disallow, "_", $k);
$body[] = implode("\r\n", array(
"Content-Disposition: form-data; name=\"{$k}\"",
"",
filter_var($v),
));
}
// build file parameters
foreach ($files as $k => $v) {
switch (true) {
case false === $v = realpath(filter_var($v)):
case !is_file($v):
case !is_readable($v):
continue; // or return false, throw new InvalidArgumentException
}
$data = file_get_contents($v);
$v = call_user_func("end", explode(DIRECTORY_SEPARATOR, $v));
$k = str_replace($disallow, "_", $k);
$v = str_replace($disallow, "_", $v);
$body[] = implode("\r\n", array(
"Content-Disposition: form-data; name=\"{$k}\"; filename=\"{$v}\"",
"Content-Type: application/octet-stream",
"",
$data,
));
}
// generate safe boundary
do {
$boundary = "---------------------" . md5(mt_rand() . microtime());
} while (preg_grep("/{$boundary}/", $body));
// add boundary for each parameters
array_walk($body, function (&$part) use ($boundary) {
$part = "--{$boundary}\r\n{$part}";
});
// add final boundary
$body[] = "--{$boundary}--";
$body[] = "";
// set options
return @curl_setopt_array($ch, array(
CURLOPT_POST => true,
CURLOPT_POSTFIELDS => implode("\r\n", $body),
CURLOPT_HTTPHEADER => array(
"Expect: 100-continue",
"Content-Type: multipart/form-data; boundary={$boundary}", // change Content-Type
),
));

Ejemplo #1 Ejemplo con CURLFile::__construct()
Estilo orientado a objetos
<?php
/* http://example.com/upload.php:
<?php var_dump($_FILES); ?>
*/
// Crea un gestor cURL
$ch = curl_init('http://example.com/upload.php');
// Crea un objeto CURLFile
$cfile = new CURLFile('cats.jpg','image/jpeg','test_name');
// Asigna los datos POST
$data = array('test_file' => $cfile);
curl_setopt($ch, CURLOPT_POST,1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
// Ejecuta el gestor
curl_exec($ch);
?>Estilo por procedimientos
<?php
/* http://example.com/upload.php:
<?php var_dump($_FILES); ?>

?>El resultado del ejemplo sería:
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)
}
