[SOLVED] Very quick REGEX Problem.

[Petsmacker]

I'm trying to get a piece of code to remove any parts of it that are not contained with brackets like these [ ]

I'm terrible at REGEX and have put this together from random other bits of REGEX around my site.

 

$tbhgcode1=preg_replace("/\[(.*?)\]/is" ,"" ,$tbhgcode1);

 

Basically what I need it to do is the opposite of what it does now, it needs to remove the bits that AREN'T in the brackets.

Can you help?

You can use the methods described here. The only difference is that it's using "<content>" instead of "[content]."

I'm sorry, I did say I was terrible with Regex, I tried to implement some of the techniques on the thread and change the tags but kept going wrong.

As a general update my script so far has got to this:

 

$tbhgcode1 = preg_replace("[\](.*?)]", "]", $tbhgcode1);

Might be easier just to match it.

If you want to keep the brackets then:

preg_match('/\[[^]]+\]/i', $tbhgcode1, $match);
echo $match[0]."\n";

Otherwise this:

preg_match('/(?<=\[)[^]]+(?=\])/i', $tbhgcode1, $match);
echo $match[0]."\n";

which will discard the brackets.
