php curl upload file code example

This article mainly introduces php curl upload file code example. This article gives two implementation methods, and gives the implementation code respectively. , friends in need can refer to it

Assume that the server-side upload file processing script upload.php:

The code is as follows:

print_r($_POST);

print_r($_FILES);

1. Use CURL’s default method

Copy the code. The code is as follows:

//If the php file is utf8 encoded and the system is GBK encoded, then you need to change the encoding, otherwise Php cannot find the file in the system

$file = realpath(mb_convert_encoding('Test picture.JPG','GBK','utf8'));

　$file = realpath('temp.jpg'); //File to be uploaded

　$fields['f'] = '@'.$file; // Add @ symbol in front to indicate uploading pictures

　$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. An alternative approach. Sometimes we need to upload dynamically generated content to a remote server as a file, but we don’t want to build a temporary file in the local server. This way we have this alternative way of writing

The code is as follows:

　$contents =<<< 'TEXT'

This is the file content, or it can be a binary image. The image needs to be modified to upload the file type

TEXT;

　$varname = 'my'; //Upload to key

　$name = '3.txt';//File name

　$type = 'text/plain';//File type

$key = "$varname"; filename="$namernContent-Type: $typern";

$fields[$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;
