- /* 9 April 2008. version 1.1
- *
- * This is the php version of the Dean Edwards JavaScript's Packer,
- * Based on :
- *
- * ParseMaster, version 1.0.2 (2005-08-19) Copyright 2005, Dean Edwards
- * a multi-pattern parser.
- * KNOWN BUG: erroneous behavior when using escapeChar with a replacement
- * value that is a function
- *
- * packer, version 2.0.2 (2005-08-19) Copyright 2004-2005, Dean Edwards
- *
- * License: http://creativecommons.org/licenses/LGPL/2.1/
- *
- * Ported to PHP by Nicolas Martin.
- *
- * ----------------------------------------------------------------------
- * changelog:
- * 1.1 : correct a bug, '/0' packed then unpacked becomes '/'.
- * ----------------------------------------------------------------------
- *
- * examples of usage :
- * $myPacker = new JavaScriptPacker($script, 62, true, false);
- * $packed = $myPacker->pack();
- *
- * or
- *
- * $myPacker = new JavaScriptPacker($script, 'Normal', true, false);
- * $packed = $myPacker->pack();
- *
- * or (default values)
- *
- * $myPacker = new JavaScriptPacker($script);
- * $packed = $myPacker->pack();
- *
- *
- * params of the constructor :
- * $script: the JavaScript to pack, string.
- * $encoding: level of encoding, int or string :
- * 0,10,62,95 or 'None', 'Numeric', 'Normal', 'High ASCII'.
- * default: 62.
- * $fastDecode: include the fast decoder in the packed result, boolean.
- * default : true.
- * $specialChars: if you are flagged your private and local variables
- * in the script, boolean.
- * default: false.
- *
- * The pack() method return the compressed JavasScript, as a string.
- *
- * see http://dean.edwards.name/packer/usage/ for more information.
- *
- * Notes :
- * # need PHP 5 . Tested with PHP 5.1.2, 5.1.3, 5.1.4, 5.2.3
- *
- * # The packed result may be different than with the Dean Edwards
- * version, but with the same length. The reason is that the PHP
- * function usort to sort array don't necessarily preserve the
- * original order of two equal member. The Javascript sort function
- * in fact preserve this order (but that's not require by the
- * ECMAScript standard). So the encoded keywords order can be
- * different in the two results.
- *
- * # Be careful with the 'High ASCII' Level encoding if you use
- * UTF-8 in your files...

- return preg_replace_callback
- (
- $regexp,
- array(&$this, '_unescapeBis'),
- $string
- );
-
- } else {
- return $string;
- }
- }
- private function _unescapeBis() {
- if (isset($this->_escaped[$this->buffer['i']])
- && $this->_escaped[$this->buffer['i']] != '')
- {
- $temp = $this->_escaped[$this->buffer['i']];
- } else {
- $temp = '';
- }
- $this->buffer['i']++;
- return $this->buffer['escapeChar'] . $temp;
- }
-
- private function _internalEscape($string) {
- return preg_replace($this->ESCAPE, '', $string);
- }
- }
- ?>
2、执行压缩的PHP文件 pack_js_file.php
- require 'tom-class.JavaScriptPacker.php';
- $t1 = microtime(true);
- $source_dir = realpath(dirname(__FILE__)."/..")."/common/script_unpacked";
- $out_dir = realpath(dirname(__FILE__)."/..")."/common/script";
- $d = dir( $source_dir );
- //echo "Handle: " . $d->handle . "/n";
- //echo "Path: " . $d->path . "/n";
- while (false !== ($entry = $d->read())) {
- if($entry=='.') continue;
- if($entry=='..') continue;
- if($entry=='.svn') continue;
- echo $entry."/n";
- $script = file_get_contents($source_dir. '/'. $entry);
- $packer = new JavaScriptPacker($script, 'Normal', true, false);
- $packed = $packer->pack();
- file_put_contents($out_dir. '/'. $entry, $packed);
- }
- $d->close();
- $t2 = microtime(true);
- $time = sprintf('%.4f', ($t2 - $t1) );
- echo 'script in ', $time, ' s.', "/n";
- die;
- ?>
3、创建一个自动执行的bat文件。
在文件中输入如下的内容:
/usr/local/php/bin/php pack_js_file.php
总结:
只要填好相对路径或者绝对路径,一键加密JS完成,那是相当的方便!! |
