Hi
Is the such a function like IN in delphi:
if( $somechar in ["a", "b", "d"])
dsafsakjldg;
where true is for the characters mentioned above.

Well, I have never used Delphi, but when you maken an array, you can
offcourse search with in_array($char,array('a','b','d'));

Delphi's in is an operation on a set of enumerated values. So strictly
speaking the answer is no.
If you're looking at finding substrings then RTM.
If you're looking at finding an element or a key in an array then RTM
My preferred version of the manual is the Windows compiled help one.

Delphi includes a group of operators that implement an area of
mathematics known as "set theory"
This is a very simple to understand area that I personally wish
was used wider - its probably easy enough for you to implement
some set constructs in whatever language you use yourself.
The other functions do the same job but operating on sets can often make
code very much clearer and hence easier to write/debug/maintain.
Do a google for "set theory" or similar - I expect there's a lot more
there.

What is wrong with if(strpos("abd", $somechar) !== FALSE)

You can do:
if (in_array($somechar, array("a", "b", "d")))
or
if (strpos(' abd', $somechar) 0)

final comment from me - one of the answers before was what I needed.
I need to test a single char, whether it is a, b or d - this could be
done in an if, but that might get pretty big and complex

I'd say I'd prefer the Delphi set construct myself too - its so much
cleaner in a number of ways - but that does the job of course.

Still overly complex by comparison I think.
In Delphi:
if "x" in ['a'..'z']
quicker to type - prettier on the eye - no question about case
sensitivity needed, easier to understand on first glance ? This thread has been closed and replies have been disabled. Please start a new discussion. Similar topics
