Does anyone know why the tag is closing?

[derwert]

1) Post only relevant parts of your code; there is no reason to post parts that have nothing to do with the problem you're having.

2) Include one or two test scenarios that show the problem you're having.

3) Try to explain you're problem more clearly; a single sentence in most cases is not enough information.

[Flare Boards]

Ok.

 

What is happening is that the <?php section is getting closed by all of the > tags in the section.

 

I cant figure out why this is happening. Is it just my FTP program that is doing this or is it the entire thing?

 

 

Thats the best that i can do :/

[derwert]

I'm still not understanding what's happening.

When you remove the meta tag and load the page what's happening?

[Flare Boards]

All of the php works up to where a > sybol comes in. Then the rest of it appears as text.

[Dragen]

do you mean the > tag here:

$replace[] = '<a href="$1">$2';

[Flare Boards]

Yes, where ever that comes in, it stops the PHP.

[Dragen]

try replacing it with:

$replace[] = '<a href="' . $1 . '">' . $2;
