/**

* jsmin.php - PHP implementation of Douglas Crockford's JSMin.
|
||||
*
|
||||
* This is pretty much a direct port of jsmin.c to PHP with just a few
|
||||
* PHP-specific performance tweaks. Also, whereas jsmin.c reads from stdin and
|
||||
* outputs to stdout, this library accepts a string as input and returns another
|
||||
* string as output.
|
||||
*
|
||||
* PHP 5 or higher is required.
|
||||
*
|
||||
* Permission is hereby granted to use this version of the library under the
|
||||
* same terms as jsmin.c, which has the following license:
