formatting meta keywords into text

I am working a little project

I need to take the keyword entered by my users and present them somewhere else.

however since my users enter the keywords on their own they are sometimes in different formats

for example,

one might have

big red cowboys

two might have

big, red, cowboys

three may have

"big red" cowboys

etc

what i need to do is take what they have no matter what and convert it to

big; red; cowboys

is this possible?

 

$keywords = implode('; ', preg_split('/[^\w-]+/', $string, -1, 1));

echo $keywords;

PHP:

 

hey thanks. i took your advice on a specific question. and i read about preg_split but to be honest i really don't get most of the preg functions

 

I'd suggest leaning the other stuff first. Learn more about the basics and things you need more often at the beginning.

And there's a very recent topic about learning Regular expressions in the PHP section, have a look at it when you think you're ready.

 

is it possible when doing the above to keep key phrases together

"big red", cowboys, hat

to

big red; cowboys; hat;
