find and replace "<" and ">" with "<" and ">" within code tags

[Giddy Rob]

Hi,

 

bit stuck on how to find and replace "<" and ">" with "<" and  ">". I basically have a database record that outputs to screen and I need the code in the <code> tags to be rendered to the screen. I therefore need it to go through the whole array variable from the db and change the symbols just inside the code tags. Please be aware that the code tags might happen more than once

 

here's an example below

 

<p>blah blah blah</p>
<p>blah blah blah</p>
<p>blah blah blah</p>
<code>
<h1>hello</h1>
</code>
<p>blah blah blah</p>
<p>blah blah blah</p>
<p>blah blah blah</p>
<code>
<h1>hello</h1>
</code>

the desired output would be:

<p>blah blah blah</p>
<p>blah blah blah</p>
<p>blah blah blah</p>
<code>
<h1>hello</h1
</code>
<p>blah blah blah</p>
<p>blah blah blah</p>
<p>blah blah blah</p>
<code>
<h1>hello</h1
</code>

 

help on this would be great

 

Cheers

You'll first need to find all the <code></code> blocks with preg_match_all using regex. Then use htmlentities to display the code as readable text

Having your code blocks be delimitted with is just a disaster waiting to happen.  This is why people usually use bbcode conventions.

Thanks guys,

 

yeah, kinda figured that out just after i posted this. Seems to work ok if you use a textarea to show the code. Just styled it so it doesnt look like one.

 

Any problems doing it this way?

You want to take all the code inside the textarea and run it through htmlentities.  Otherwise, it's a good solution.
