Hi all

I have just written a blog in php and was looking at this thing called PHPBB.

 

Can someone explain to me what this is, does it mean that i can insert php code into my blog and it will change the colours accordingingly???

 

Thanks

phpBB is forum software. Got to phpbb.com for more info.

I dont really understand it fully.. is it a long winded thing to install and configure etc?? does it edit the entire database??

 

 

[wildteen88]

PHPBB is a forum like this one here. Are you wanting to install a forum?

 

PHPBB will install its own database.

No, what im trying to do is be able to insert php code into my blog then when it is outputted the colors - just like it is here - i wanna use the [ code ] tags just like here so it changes the colour of php text.

Oh! You're after BBCodes. There are many tutorials for adding BBCodes to your site.

Can you point me in the right direction.... is their something i need to install onto my server or is it a simple thing to do??

No need to install anything. You just write the necessary code for your BBCode parser.

 

In order to write your own you'll need to know some basic PHP syntax and have an understanding of regular expressions.

Took me 3 minutes to put in "Colour PHP Code" into google and those were the first two links, both of which will get you going in the right direction

Hi I made a class: Seems to work fine for most:

 

<?php

class Phpposter{

	var $border;
	var $padding;
	var $width;
	var $margin_bottom;
	var $bg_color;
	var $font_size;

	function Phpposter(){
		$this->border = "1px #CCCCCC solid";
		$this->width = "500px";
		$this->margin_bottom = "5px";
		$this->padding="3px";
		$this->bg_color="#FFFFFF";
		$this->font_size="14px";
	}

	function highlight_code($string){
		//We're looking for [code] tags here. 
		$pattern = "/\[code\](.*?)\[\/code\]/is";
		preg_match_all($pattern, $string, $matches); //Find all matches
		$changes = array(); //This array will hold all the changes we made. These changes will replace the matches.

		if(sizeof($matches) < 1){ //If no code tags are found, return the string as it was
			return $string;
		}

		else{
			foreach($matches[1] as $match){
				array_push($changes,$this->style($match));//Fill up changes array
			}
		}


		$i=0;//counter
		while($i < sizeof($matches)){
			$string = str_replace($matches[1][$i],$changes[$i],$string);
			$i++;
		}

		$string = str_replace("[code]","",$string);
		$string = str_replace("

","",$string);

 

return $string;

 

}

 

function style($string){

 

$div =

'<div style="background-color:'.$this->bg_color.';

width:'.$this->width.';

padding:'.$this->padding.';

border:'.$this->border.';

margin-bottom:'.$this->margin_bottom.';

font-size:'.$this->font_size.';

white-space: pre;

overflow: auto;">';

 

$string = str_replace("<br />","",$string);

$string = str_replace("<br/>","",$string);

$string = str_replace("\n","",$string);

 

$string = '<br/>'.$div.highlight_string($string,true).'</div>'; //Place div around code to make it stand out

return $string;

 

}

 

function set_width($width){

$this->width=$width;

}

 

function set_margin_bottom($margin_bottom){

$this->margin_bottom = $margin_bottom;

}

 

function set_border($border){

$this->border = $border;

}

 

function set_font_size($font){

$this->font_size = $font;

}

 

function set_bg_color($bg){

$this->bg_color = $bg;

}

 

function set_padding($padding){

$this->padding = $padding;

}

}

 

?>

[/code]

 

Basic gist of how to use:

 

$phpposter = new Phpposter();
echo $phpposter->highlight_code($blogpost);

In a moment someone will tell you that you shouldn't use PHP4-style OOP. They'll also tell you that you should use the setter methods you've created and that you should just set default values instead of doing it in the constructor. Moreover, you'll be told that instead of tracking "changes" you should just use preg_replace_callback() to replace matches.

Oh I know that the code is not without its fault. Oh and the PHP 4-style constructor is a habit I have from Java. The class was kind of rushed together. It works and I use it personally; so I wont lose any sleep over it. I'll keep what you said about what I didn't know in mind though. Thanks.
