PHP 多部分表单数据 PUT 请求？

首先，在处理 PUT 请求时不填充。它仅在处理 POST 请求时由 PHP 填充。$_FILES

您需要手动解析它。这也适用于“常规”字段：

// Fetch content and determine boundary
$raw_data = file_get_contents('php://input');
$boundary = substr($raw_data, 0, strpos($raw_data, "\r\n"));

// Fetch each part
$parts = array_slice(explode($boundary, $raw_data), 1);
$data = array();

foreach ($parts as $part) {
    // If this is the last part, break
    if ($part == "--\r\n") break; 

    // Separate content from headers
    $part = ltrim($part, "\r\n");
    list($raw_headers, $body) = explode("\r\n\r\n", $part, 2);

    // Parse the headers list
    $raw_headers = explode("\r\n", $raw_headers);
    $headers = array();
    foreach ($raw_headers as $header) {
        list($name, $value) = explode(':', $header);
        $headers[strtolower($name)] = ltrim($value, ' '); 
    } 

    // Parse the Content-Disposition to get the field name, etc.
    if (isset($headers['content-disposition'])) {
        $filename = null;
        preg_match(
            '/^(.+); *name="([^"]+)"(; *filename="([^"]+)")?/', 
            $headers['content-disposition'], 
            $matches
        );
        list(, $type, $name) = $matches;
        isset($matches[4]) and $filename = $matches[4]; 

        // handle your fields here
        switch ($name) {
            // this is a file upload
            case 'userfile':
                 file_put_contents($filename, $body);
                 break;

            // default for all other files is to populate $data
            default: 
                 $data[$name] = substr($body, 0, strlen($body) - 2);
                 break;
        } 
    }

}

在每次迭代中，数组将填充您的参数，并且数组将使用每个部分的标头（例如：等）填充，并且将包含原始文件名（如果在请求中提供并且适用于该字段）。$data$headersContent-Type$filename

请注意，上述内容仅适用于内容类型。在使用上述内容解析正文之前，请务必检查请求标头。multipartContent-Type

请不要再删除它，这对大多数来这里的人都有帮助！所有以前的答案都是部分答案，没有涵盖大多数提出这个问题的人想要的解决方案。

这采用了上面所说的内容，并额外处理多个文件上传，并将它们放在$ _FILES中，正如人们所期望的那样。要使其正常工作，您必须将“脚本PUT / put.php”添加到每个文档的项目的虚拟主机中。我还怀疑我必须设置一个cron来清理任何“.tmp”文件。

private function _parsePut(  )
{
    global $_PUT;

    /* PUT data comes in on the stdin stream */
    $putdata = fopen("php://input", "r");

    /* Open a file for writing */
    // $fp = fopen("myputfile.ext", "w");

    $raw_data = '';

    /* Read the data 1 KB at a time
       and write to the file */
    while ($chunk = fread($putdata, 1024))
        $raw_data .= $chunk;

    /* Close the streams */
    fclose($putdata);

    // Fetch content and determine boundary
    $boundary = substr($raw_data, 0, strpos($raw_data, "\r\n"));

    if(empty($boundary)){
        parse_str($raw_data,$data);
        $GLOBALS[ '_PUT' ] = $data;
        return;
    }

    // Fetch each part
    $parts = array_slice(explode($boundary, $raw_data), 1);
    $data = array();

    foreach ($parts as $part) {
        // If this is the last part, break
        if ($part == "--\r\n") break;

        // Separate content from headers
        $part = ltrim($part, "\r\n");
        list($raw_headers, $body) = explode("\r\n\r\n", $part, 2);

        // Parse the headers list
        $raw_headers = explode("\r\n", $raw_headers);
        $headers = array();
        foreach ($raw_headers as $header) {
            list($name, $value) = explode(':', $header);
            $headers[strtolower($name)] = ltrim($value, ' ');
        }

        // Parse the Content-Disposition to get the field name, etc.
        if (isset($headers['content-disposition'])) {
            $filename = null;
            $tmp_name = null;
            preg_match(
                '/^(.+); *name="([^"]+)"(; *filename="([^"]+)")?/',
                $headers['content-disposition'],
                $matches
            );
            list(, $type, $name) = $matches;

            //Parse File
            if( isset($matches[4]) )
            {
                //if labeled the same as previous, skip
                if( isset( $_FILES[ $matches[ 2 ] ] ) )
                {
                    continue;
                }

                //get filename
                $filename = $matches[4];

                //get tmp name
                $filename_parts = pathinfo( $filename );
                $tmp_name = tempnam( ini_get('upload_tmp_dir'), $filename_parts['filename']);

                //populate $_FILES with information, size may be off in multibyte situation
                $_FILES[ $matches[ 2 ] ] = array(
                    'error'=>0,
                    'name'=>$filename,
                    'tmp_name'=>$tmp_name,
                    'size'=>strlen( $body ),
                    'type'=>$value
                );

                //place in temporary directory
                file_put_contents($tmp_name, $body);
            }
            //Parse Field
            else
            {
                $data[$name] = substr($body, 0, strlen($body) - 2);
            }
        }

    }
    $GLOBALS[ '_PUT' ] = $data;
    return;
