Sublime Text3 破解

转:http://bbs.pediy.com/showthread.php?t=182774

需要解决 utf-8 支持问题。只是普通的转换。比较蛋疼

破解使用.

只是个超级记事本。相对来说挺适合php这类东东。但是没有zend studio强劲.

稍微比editplus强点点。

CURL 文件上传兼容 php5.4-5.5

	public function getCurlValue($filename, $contentType) {
		// PHP 5.5 introduced a CurlFile object that deprecates the old
		// @filename syntax
		// See: https://wiki.php.net/rfc/curl-file-upload
		if (function_exists ( 'curl_file_create' )) {
			$filename = preg_replace ( '/^@/', '', $filename );
			return new CurlFile ( $filename, $contentType, basename($filename) );
			// curl_file_create ( $filename, $contentType, basename($filename));
		}
		// Use the old style if using an older version of PHP
		if (! preg_match ( '/^@/', $filename ))
			$value = "@" . $filename;
		else
			$value = $filename;
		return $value;
	}

curl_setopt ( $ch, CURLOPT_POSTFIELDS, $data ); // POST提交的数据包

if ($data) {
			foreach ( $data as $key => $file ) {
				$data [$key] = $this->getCurlValue ( $file, $this->get_mime ( $file ) );
			}
		}

	function get_mime($file) {
		$ext = pathinfo ( $file, PATHINFO_EXTENSION );
		if ($ext == '')
			return '';
		$mime_types = include 'mime.class.php';
		return isset ( $mime_types [$ext] ) ? $mime_types [$ext] : '';
