PHP-php Tutorial

This article mainly introduces the phpcurl file upload code example. This article provides two implementation methods and the implementation code respectively, for more information, see upload. php:

The code is as follows:

<? Php

Print_r ($ _ POST );
Print_r ($ _ FILES );

1. use the default CURL method

The code is as follows:

// If the Php file is utf8 encoded and the system is GBK encoded, it needs to be converted to the next encoding. otherwise, Php cannot find this file in the system.
$ File = realpath (mb_convert_encoding ('test Image. JPG ', 'gbk', 'utf8 '));

$ File = realpath('temp.jpg '); // the object to be uploaded
$ Fields ['F'] = '@'. $ file; // add a @ symbol to upload an image.

$ 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. alternative practicesSometimes we need to upload the dynamically generated content to the remote server as a file, but we do not want to build temporary files on the local server. In this way, this alternative writing method is available.

The code is as follows:

$ Contents = <'text'
This is the file content, or the image binary. you need to modify the Upload file type for the image.
TEXT;

$ Varname = 'my'; // key uploaded to 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;
