PHP Curl Upload File code example, _php tutorial

PHP Curl Upload file Code instance,

Suppose the server-side upload file processing script upload.php:
Copy the Code code as follows:
<?php

Print_r ($_post);
Print_r ($_files);

1, using the default method of CURL
Copy the Code code as follows:
If the PHP file is UTF8 encoded, the system is GBK encoded, then you need to turn the code, or PHP can not find this file in the system
$file = Realpath (mb_convert_encoding (' Test picture. JPG ', ' GBK ', ' UTF8 ');

$file = Realpath (' temp.jpg '); The file to upload
$fields [' f '] = ' @ '. $file; Preceded by an @ symbol to upload a picture

$ch =curl_init ();


curl_setopt ($ch, Curlopt_url, ' http://localhost/upload.php ');

curl_setopt ($ch, curlopt_post,true);
curl_setopt ($ch, Curlopt_postfields, $fields);
curl_setopt ($ch, curlopt_returntransfer,true);


$content = curl_exec ($ch);

Echo $content;

2, the alternative approach , sometimes we need to be dynamically generated content as a file upload to the remote server, but do not want to build a temporary file on the local server. This is the alternative way of writing.

Copy the Code code as follows:
$contents =<<< ' TEXT '
Here is the file content, can also be the picture binary, the picture needs to modify the upload file type
TEXT;

$varname = ' my ';//upload to key in the $_files array
$name = ' 3.txt ';//File name
$type = ' text/plain ';//File type

$key = "$varname \"; Filename=\ "$name \r\ncontent-type: $type \ r \ n";
$fields [$key] = $contents;



$ch =curl_init ();


curl_setopt ($ch, Curlopt_url, ' http://localhost/upload.php ');

curl_setopt ($ch, curlopt_post,true);
curl_setopt ($ch, Curlopt_postfields, $fields);
curl_setopt ($ch, curlopt_returntransfer,true);


$content = curl_exec ($ch);

Echo $content;
