how to upload file using curl with php
提问by Hadidi44
I want to know how to upload file using cURL or anything else in PHP. I have searched in google many times but no results.
我想知道如何使用 cURL 或 PHP 中的任何其他内容上传文件。我在谷歌搜索了很多次，但没有结果。
In other words, the user sees a file upload button on a form, the form gets posted to my php script, then my php script needs to re-post it to another script (eg on another server).
换句话说，用户在表单上看到一个文件上传按钮，表单被发布到我的 php 脚本，然后我的 php 脚本需要将它重新发布到另一个脚本（例如在另一台服务器上）。
I have this code to receive the file and upload it
我有这个代码来接收文件并上传它
code :
代码 ：
echo"".$_FILES['userfile']."";
$uploaddir = './';
$uploadfile = $uploaddir . basename($_FILES['userfile']['name']);
if ( isset($_FILES["userfile"]) ) {
echo '<p><font color="#00FF00" size="7">Uploaded</font></p>';
if (move_uploaded_file
($_FILES["userfile"]["tmp_name"], $uploadfile))
echo $uploadfile;
else echo '<p><font color="#FF0000" size="7">Failed</font></p>';
}
I want the code to send the file to receiver file.
我希望代码将文件发送到接收器文件。

Use:
用：
if (function_exists('curl_file_create')) { // php 5.5+
$cFile = curl_file_create($file_name_with_full_path);
} else { //
$cFile = '@' . realpath($file_name_with_full_path);
}
$post = array('extra_info' => '123456','file_contents'=> $cFile);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,$target_url);
curl_setopt($ch, CURLOPT_POST,1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $post);
$result=curl_exec ($ch);
curl_close ($ch);

Important hint for PHP 5.5+:
PHP 5.5+ 的重要提示：
Now we should use https://wiki.php.net/rfc/curl-file-uploadbut if you still want to use this deprecated approach then you need to set curl_setopt($ch, CURLOPT_SAFE_UPLOAD, false);
现在我们应该使用https://wiki.php.net/rfc/curl-file-upload但如果您仍然想使用这种已弃用的方法，那么您需要设置curl_setopt($ch, CURLOPT_SAFE_UPLOAD, false);
