The longest word in the world!

[rarebit]

Hi,

I have a section which if your that way inclined, you might just try to put one massive word (all same letter) in.

So i'm just looking for ideas of how to catch it. I've thought of a regex '/ [a-z]{11+} /', but i'd rather not use regex, so...

The string could be exploded on the space, then check for the longest word...

? ? ?

 

 

EDIT:

just for fun:

Say I have textarea which is entitled, 'Tell us a bit about yourself' and in this box old joe puts 'testttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttt', well I intend to reject it.

regex takes time to compile a search query and then to run it, so i'm wondering if it'd be quicker to do it myself, with an explode or my own char by char search (for a quick exit)

NA, regex would be faster..

 

oh you doing this in a database query ?

infact never mind

[samshel]

anyways regex would be safe and fast...

yep, I love wasting time...
