Whats the difference?

[newbtophp]

Difference between .+? vs .*? and which is better/recommended (in most cases - out of the two)?

[Alex]

+ means match one or more and * means match 0 or more. Which is better depends on the situation.

[newbtophp]

+ means match one or more and * means match 0 or more. Which is better depends on the situation.

 

So what about:

 

(.+?) or (.*?)

 

Which would be the best in this situation?

[Alex]

That's not a situation.. What are you trying to match? If there was a case where something you might be matching isn't required to be there at all then you would use *, but if there needs to be 1 or more then use +.

[newbtophp]

Its their but the bbcode got parsed (view src to see lol), so i'll wrap it in a code tag so it doesnt:

[b](.+?)[/b]

//or

[b](.*?)[/b]

 

Which would be better within a preg_replace? (for a simple bbcode parser)

There's not much point in bolding nothing. 

[newbtophp]

There's not much point in bolding nothing.

 

so use (.+?)

 

As the + matches only if it contains 1 character or more right? (correct me if im wrong)

[Alex]

Yes, that's correct.
