[Resolved] replacement between tags

[krelian]

I am trying to replace stuff between tags, and I couldn't turn up anything from the search. I have also tried the documents here on the site, but I still cannot get it to work.

Anyway, I want to take something that looks like this:
This text is bold
And make it appear like this:
<b>This text is bold</b>

So pretty much, stripping out the HTML from the code. I want it to find any parts that are between only the <b> tags, and change <b></b> so that they appear on my page. Any help would be great!

Replace all <s with &lt; and all >s with &gt;.

That'll make the HTML show.

Hi.
if you want to strip data from <b>...</b> tags you should do some programming stuff. I have written a function to do that. If you are interested contact me.

Sorry, I mustn't have been clear enough the first time. I don't want to replace the < and > characters, I want to change just the bold parts so that they appear with <b>Here</b>. I don't want all of my code to be visible... well, you know what I mean, just the sections that I desire.

HTML is HTML

If you want to write HTML out without it being interpreted as HTML, you must use &lt; and &gt; which will turn into < and > in your pages (this forum software prevents &lt; from being interpreted).

This is not a PHP problem.

Yes, I'm quite aware of that.

But I want to strip out just the bold tags from my pages, for all bold markings, not just one. I don't plan on doing this manually, and the information is taken from a database.

This is a simple preg_replace, but I cannot figure out how to carry over the information just between the tags. It comes up looking like:
<b>\5</b>.
So, how to turn:
This is a returned row from the database with bold tags. There are also more comming.
to
&lt;b&gt;This is a returned row from the database with bold tags. There are also more comming.&lt;/b&gt;

Now does that make sense?

If they're just bold tags then

$string = str_replace('<b>', '&lt;b&gt;', $string);
$string = str_replace('</b>', '&lt;/b&gt;', $string);

You can get fancy and consider things like attributes and suchforth, and come up with an all-singing all-dancing bold-tag-escaper with a preg_replace

$string = preg_replace('#<(/?)b(\s[^>]*)?>#', "&lt;$1b&gt;", $string);

assuming you don't want to retain the attributes.

Then to strip the other tags it's just a call to strip_tags.
