helouuuu, php is not a programing language, have u ever heard of server-side scripts? [#3307]

Comment by viperxp45 (published 2007-05-04)
awsome [#3304]

Comment by Graham (published 2006-06-01)
Yes - because I have no element preceeding the quoted regular expression on that particular question, the 2 or 3 letters could be preceeded by other letters as you state, thus making it "2 or more letters". Noted, question updated. Thanks for the inputs [#3132]

Comment by Anon (published 2006-06-01)
This is true, the proper answer would be the one chosen. If the question stated [a-z]{2,3,}$ then the said correct answer would be the choice. [#3114]

Comment by curtis (published 2006-03-25)
Thorough, well-planned PHP quizes! I found one question in the intermediate quiz which said I was wrong, when, indeed, I was not:

The regular expression [a-z]{2,3}$ will only match

YOU WERE INCORRECT

The answer you gave:
any string that ends with 2 or 3 lower case letters

Correct Answer:
any string that ends with 2 or more lower case letters

[a-z]{2,3} will match only 2 or 3 lower case letters at the end of a string, not 2 or more. [#340]
