/* 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 () 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 () Copyright , 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();
* $myPacker = new JavaScriptPacker($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.
* # 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...
