Displaying php code in a php page

danielneri

I have a script which pulls articles from a database, but some of the articles have php code in them that i want to DISPLAY rather than EXECUTE

does anybody have any ideas?

pfgannon

heh that sucks.

I've read on how to solve this but I can't say that I remember how to do it.
Sorry:(

If you're not planning on using PHP's inbuilt PHP code highlighter, it's as simple as:
[PHP]<?php
$variable = "This is the code:
<?php echo 'code'; ?>";
$variable = str_replace("<", "<", $variable);
$variable = str_replace(">",">", $variable);
?>[/PHP]
If you plan to use PHP's highlighter, it's a bit different, but the highlighter isn't much good unless you don't mind not being able to easily highlight other languages (it only works on PHP by default).
The basic jist of it is that HTML is designed so that code won't get rendered as anything other than text unless it's HTML tags or CSS, ASCII character codes or a few other things.

Get the contents you want from your DB and store it in a variable so you can work on it before echoing it to the output.
Ideally, you should do this before inserting the article into the database since it will add to the loading time if you do it each time the end user load the article (it also adds to server load).
If you do it before insertion, you only increase server load and loading times when you insert articles and when you edit them (because you have to convert the tags and such).

so could you help me out here? i right now have no flying clue what to do!

You know when you insert an article into the DB?
Before inserting it with the mysql query, you'd want to use the code I posted above to change:
[php]
mysql_query("INSERT blah blah");
[/php]

to:
[php]
$article = $_GET;
$article = str_replace("<","<",$article);
$article = str_replace(">",">",$article);

mysql_query("INSERT blah blah but using the modified body of the article");
[/php]

I have a very lame script which enables highlighted PHP code blocks, but due to the way it's built, posting it here is a bit funky (it uses the [ php ] tags vB also uses, thus causing problems when written here).

Anyway, I'm in the process of rewriting a BBCode parser which should be useful for getting people started with writing such things.
I'll do that (shouldn't take long) and post it here.
It should have the PHP highlighting code in with it.

danielneri
