nl2br keeps writing new <br/> tags

[Gibbs]

I currently have two functions that convert bb to html and vice verse. At the bottom of these two functions I am using:
[code]$string = nl2br($string);[/code]

When I write new code via my editor I have created it keeps adding more <br/> tags I haven't asked for.

For example this

[code][img]image[/img]<br />
[b]Text 1[/b] Text2[/code]

Changes to this

[code][img]image[/img]<br /><br />
[b]Text 1[/b] Text2 <br />[/code]

Is there a way to stop it writting more <br/> tags?

Thanks

you'd have to do
[img]http://image[/img]<br />[b]Text 1[/b] Text2

not
[img]http://image[/img]<br />
[b]Text 1[/b] Text2

There's a NL in there, plus an existing BR. So, you get two BRs. That IS what you've asked for.

Gah. Stupid code.

Do this:
[code][img]image[/img]<br />[b]Text 1[/b] Text2[/code]
or this:
[code][img]image[/img]
[b]Text 1[/b] Text2[/code]

Thanks for your reply but it didn't help.

Whenever I hit "Update Page" on my editor WITHOUT editing or touching it new breaks are added each time...

In addition to jesirose's explanation, I would challenge you to consider [b]when[/b] you are running your parser. If you run your parser when you [i]output[/i] your code, you should be fine; however, if you run your parser on it when your [i]input[/i] the code, it will be saved with the new tags [b]and[/b] the line breaks in there, so every time you edit it, you'll have another BR tag added on.

Ah thanks. The reason was that the <br/> tags got added, as told to, but on opening the file it added new ones as the old ones were only being displayed.

Difficult to explain. Your replies helped a lot though.

Thank you jesirose and obsidian  ;D
