BB Code using PHP?

[Jibba Jabbas]

How do i go about using PHP when creating new BB Codes? Basically i want to create a new BB Code and i need to use the text between it in a PHP script...

So the process is like this:

[bbcode]test[bbcode]

Then a PHP script is run which has say $x = the user input.. in this case "test".

Then i after using that input to gather the relevant data i have it all in $a and want to print the contents of $a on the screen.

So it goes from [bbcode]test[/bbcode] to showing the contents of $a.

How do i go about doing this?

Thanks

It is easy if you know regular expressions. Here is the code you need: (Assuming that the code between the tags will be a string that doesn't contain whitespace.

PHP Code:

preg_match_all("#\[bbcode\](\w+)\[\/bbcode\]#i",$template,$matches);

foreach($matches[0] as $value){
//$value contains the each instance of entire blocks matched "[bbcode]stringWithoutWhitespace[/bbcode]"
}

foreach($matches[1] as $value){
//$value contains each instance of only stringWithoutWhitespace between the tags.
} 


I hope this is helpful.

But can that be input into the HTML box when you create a new bbcode using admin cp?

Once i get the bit in the middle i need to do something with it through PHP then the output needs to go onto the page.
