EPJ stream wrapper, EPJ stream wrapper Options

[Efox]

I've written this just for testing:

CODE

<?php
class epjStream
{
var $position = 0, $resource;
function sanitize($c)
{
if(strpos($c,'<?')!==false&&strpos($c,';')!==false)
{
$a = array('ú','ã','á','ê','é','ç','ó','â','ê','ç','ú','ó','ã','É','õ','õ','ô','Ü','°','ñ');
$b = array('ú', 'ã', 'á', 'ê', 'é', 'ç', 'ó', 'â', 'ê', 'ç', 'ú', 'ó', 'ã', 'É', 'õ', 'õ', 'ô', 'Ü', '°', 'ñ' );
$c = utf8_decode(str_replace($a, $b, $c));
}
return $c;
}
function parse($path)
{
$path = str_replace(array('\\','epj://'),array('/',''),$path);
$file = substr($path, 0, strrpos($path,'#'));
$section = substr($path, strrpos($path,'#')+1);
return compact('file', 'section');
}
function stream_open($path, $mode, $options, &$opened_path)
{
$path = $this->parse($path);
extract($path);
if(!isset($GLOBALS[$file]))
{
$GLOBALS[$file] = array();
if($buffer = file_get_contents($file))
{
$buffer = explode('<resource>', $buffer);
foreach($buffer as $fragment)
{
if(stripos('<data', $fragment)!==false) continue;
$name = explode('name>', $fragment);
$type = explode('type>', $fragment);
$data = explode('data>', $fragment);
if(sizeof($data)>1)
{
$name = substr($name[1], 0, -2);
$type = substr($type[1], 0, -2);
$data = substr($data[1], 0, -2);
$GLOBALS[$file][$type.'/'.$name] = $this->sanitize(base64_decode($data));
}
}
}
}
$this->resource = isset($GLOBALS[$file][$section])?$GLOBALS[$file][$section]:'';
return true;
}
function stream_read($count)
{
$ret = substr($this->resource, $this->position, $count);
$this->position += strlen($ret);
return $ret;
}
function stream_stat()
{
return array('dev'=>771,'ino'=>488704,'mode'=>33188,'nlink'=>1,'uid'=>0,'gid'=>0,'rdev'=>0,'size'=>strlen($this->resource),'atime'=>time(),'mtime' => time(),'ctime' => time(),'blksize' => 4096,'blocks' => 8);
}
function stream_write($data) { return false; }
function stream_tell() { return $this->position; }
function stream_eof() { return $this->position >= strlen($this->resource); }
function stream_seek($o, $w =0 ) { $this->position = $o + $w; return true; }
}

stream_wrapper_register('epj', 'epjStream') or die('Failed to register epj protocol');

include_once('epj://megacubo.epj#PHP/MAIN');
echo file_get_contents("epj://C:\\teste.epj#TXT/DATA");

?>

The sanitize function I've added just to prevent some strange UTF8 chars that was in my testing project and may be removed. If you have better solutions post here!

I like it Very interesting implementation using user streams.
You always happen to surprise me, keep it up!
