OK well I am making a new php program and I am trying to add bbcode to it. Anyway I was going to replace each thing by it self, but that could cause errors. Anyway is there a way to make a variable be anything? Here is an example:

CODE

This is the bbcode:
[color=00FF00]Hey[/color]
In my php:
$bbcode = array("[color=".$a."]");
$html = array( "<font color='#".$a."'>");
$topic_content = str_replace($bbcode, $html, $posted_bbcode);

So I want $a to be any variable but the same variable as used before. Do you get what I am saying? It is a little confusing but basicly what is the best way to make bbcode? It may not even involve the str_replace but this was the easyiest way to explain what I wanted.

Thanks for everyone that helps,
Sparkx

It can be done in several ways, but as for your problem, I think you could just use a regular expression, even though I like to avoid them, I never got into regular expressions, just found them or asked for them on IRC channels, you would need to use preg_replace(); read on it on the php manual

Quickly Create Form Variables - simple form, variable creation, referer check, safe guard variables (5)

The reason I wanted to share this is I've seen so many people do this with their forms when
using PHP. CODE $username = $_POST ; $password = sha1($_POST ); $another_var = $_POST ; ...
and so on, just imagine if you had a large number of form inputs, do you really want to create each
and every variable name? Why people do this, is probably due to most of the examples I've seen
on the web, that does not show an easier and much quicker way of doing it. Though my way might be
much easier and quicker, it does introduce security concerns which I've tried...

Php Variable Concatenation - Something New I learned Today! :P (7)

I was coding one of my php page today, when I realized that I had to add multiple values to a
variable (now that I think of it, a solution with arrays is possible too). But, the problem is that
I have to add them in different parts of the code, so the new line that defines the variable will
cover up the previous one. I played around with the code, and I finally got this solution:
$message = "test1"; $message .= "test2"; $message .= "test3"; echo $message; By adding a dot in
front of the = sign, I could concatenate the previous value with the new one and put them i...
