[PHP] url rewritting in php5
Hello!
I'm solving one problem and I'd like to ask you for hints/advices or
'RTFM at link' answers.
Problem is:
I need special type of URL to be 'rewritten' in the way how the Apache
does the URL rewritting.
example:
fopen('chrome://myfile.txt', 'r');
to have be internaly resolved for eaxample as
fopen('/var/www/localhost/chrome/myfile.txt', 'r');
I know that there is the way how to register url wrapper in PHP5. It is
the solution. But I do not need to implement whole API.
Is there way to do something like this?
class ChromeWrapper extends PHP_STD_FILE_WRAPPER {
function stream_open($path,$mode,$opts,$opened_path) {
$path=str_replace('chrome://', '/var/www/localhost/chrome/', $path);
parent::stream_open($path, $mode, $opts, $opened_path);
}
}
... simply implement easily only the path rewritting instead of
implementing all the functions that are already done in built-in api.
Or is there some way how to register 'filter' that filters $path instead
of the content?
Thank you for sharing your knowledge

Re: [PHP] Question on functions
I'm not certified expert ;-) but what I meant is
Do not use function that writes to the hardcoded global variables:
example:
function db() {
...
$GLOBALS['db']=x_open_something($GLOBALS['...'], ...);
...
}
This function is really... hm... not flexible enough ;-)
It can make the job done well but... what if you need to open second
connection? What if you have news data stored on other server or in
defferent database under diferent user/password? Hm. What you will do?
You probably create function db2(), yes? And what if you need to read
page hit statistic from another database? ... db3()? ... db4()? Do you
see the problem?
'functions' are pieces of GENERIC code doing the same thing with
different input and resulting in possible different output... What you
typed was not GENERIC - it was really one-purpose code that didn't need
to be placed in function at all... You could simply include content of
db() into your log() method and result would be the same...
I recomend to go this way (I modified your code, I didn't test it so
typos/mistakes can be there - just showing the idea)...
/* User Defined Variables */
$defined = array( host = localhost, user = user, pwd =
password );
$defined2 = array( host = localhost2, user = user2, pwd =
password2 );
logs(db($defined));
logsOnOtherMachine(db($defined2)); // Little bit more flexible so you
can use it for other purposes as well
/* Database connection */
function db($cfg) {
if( connection_status() != 0 ) {
$db = @mysql_pconnect( $cfg['host'], $cfg['user'], $cfg['pwd']) or
die('connection problem...');
}
return $db;
}
/* Logging function */
function logs($db) {
global $defined;
if (!$db) {
trigger_error('Connection was not established!', E_USER_ERROR);
return false;
}
$pagecount = 1;
$tble = logs;
$sql = @mysql_query( SELECT * FROM ..., $db ) or die( problem... );
// your stuff...
}
function logsOnOtherMachine($db) {
...
}
And if you would be really trying to dig in... have a look at OOP
implementation in PHP... After the beginner's pain you will love it ;-)
Hope I helped little.

[PHP] RDF/XML Parser: SimpleRDF
Hi all, I was looking for an easy RDF parser writen in PHP but I failed. There are some parsers out there but I could not find the right one for me... I decided to write an RDF parser by myself... not easy ;-)... I created SimpleRDF parser on sourceforge.net under BSD license and I'd like to ask you guys for help. If you have time to play little bit with RDF or you are looking for RDF/PHP parser - test mine (even if you don't expect to use it - just try it, please). I'm currently working on version 0.2 that has the ability to save (for now it can only read/parse and save N-Triples) RDF/XML documents. SimpleRDF is based on PHP5/XSL. XSL part simplifies the RDF/XML source to allow easy parsing (XSL part can be used as standalone XSL stylesheet if you need). PHP5 part provides really simple API - my goal was really KISS (keep it simple, stupid). It is well commented. Thanks for any testing/feedback...

Re: [PHP] Question on functions
Or you can use superglobal variable $GLOBALS that is array containing
all GLOBAL variables. This variable is superglobal thus does not need to
be declared global using 'global $GLOBALS;' statement. Works anywhere.
function database() {
... $GLOBALS['array'][0], $GLOBALS['array'][1] ...
}

Tip: I recommend to not use GLOBALS for this type of data. Better use
function parameters - function database($host, $user, $pwd, $db) {...}
It will save you time when your application grows and starts clashing
with other global variables or third party pieces of code ;-)

My question is in regard to passing global variables to a function.
Here is my code, any idea why it is not working? I suppose my
understanding of a global variable being able to be used within a
function is off?
global $array = array( 0 = hostname, 1 = username, 2 =
password );
function database()
{
You need to declare it global within the function...
function database()
{
global $array;
...
thanks, it figures it is something easy like that... =)

[PHP] Re: Multiple session_start()s / Is it a problem??
I guess that session_id() method will return null if session is not started (not tested) so theoreticaly you can use: if (!session_id()) session_start(); elixon Al wrote: Is there a problem issuing multiple session_start()s for a given script? I can't find anything in the manual that says one way or the other. I have some scripts that call more than one functions include file and for convenience put a session_start() on each one. This gives me a Notice error. Of course I can simply use @session_start() to negate the Notice; but, I want to be certain this is good practice.

[PHP] Re: Multiple session_start()s / Is it a problem??
And I think that $_SESSION does not exist unless session is started = if (!is_array($_SESSION)) session_start(); might do the job as well. elixon Al wrote: Is there a problem issuing multiple session_start()s for a given script?
