a few quick questions

nosix

This is my first post on these forums so let me first say hello to everyone thanks to whoever the webmasters are for making a newbie forum for ppl like myself...I am sure I will put it to good use 🙂

Now on to the questions...

1.) What (if any) difference is there, between $PHP_SELF and $REQUEST_URI ??? My guess is a matter of speed but I have not tested them yet for speed so I don't know...

2.) What would be the best way to print out a url without the filename.ext part of the address ???

Ex. printing out a url that looks like this

http://somesite.com/somedir

instead of one that looks like this

http://somesite.com/somedir/filename.ext

I am currently using the following code and it works but I don't know if it's the best/right way to do it...

<? print ("http://").($SERVER_NAME).dirname($REQUEST_URI); ?>

3.) Finally, Does Anyone know of a script or function that automatically adds links any predefinded php function names which when clicked go to their respective documentation on php.net. (An example of what I am talking about can be found here )

As you can see all the code on this page is highlighted and all of php's predefined function names are active links which when clicked on take you to the docs for that function... I know this could be done with a series of preg_replace tags but this would take a great deal of time to do and the script that included all of those tags would be huge and chances are it would timeout before it even finished doing it's job so there has to be a better way... I am just not sure what that better way is...

Thanks in advance,

as for #3, you can use the functionality PHP.net already has built into their site. if you use a link as such... http://www.php.net/manual-lookup.php?pattern=functionNameHere&lang=en and replace that portion with the real function name, you will automatically be taken to the proper page...i.e. -> http://www.php.net/manual-lookup.php?pattern=str_replace&lang=en

I don't understand what you are saying but I don't think it is exactly what I am talking about...

What I want is to type something in a form (Anywhere on my site) like the word "echo" and for it to automatically become a link to the php.net site when I print it out...

The whole point is I don't want to type out the entire url by hand I want a script to proccess the word "echo" and replace it with "http://php.net/echo" automatically...

As I said before I know I can do this if make a script that list every predefined function php has and replace it like this...

$txt = preg_replace( "#foreach#"  , "<a href=http://php.net/foreach target=_blank>foreach</a>", $txt );

but I would have to do the above for each predefined function php has and the file would be so big it would timeout before it got to the end but I don't know any other way and was hoping someone else might...
