How to match string inside of array?

[somebody]

If I have an array like:

@arr = ('one', 'two', 'three');

And the varaible $myvar = 'two';


How do I check if $myvar matches 'two' in @arr?

I know I could iterate through the array with
a foreach statement, but was wondering if there
was a more efficient method.

-Thanks

I don't seem to have that. Is it a separate module?

mybox:> perldoc -q contains
No documentation for perl FAQ keyword `contains' found

In my version (5.8.6) you have to search for "contained"

FYI to OP: this newsgroup is defunct; try comp.lang.perl. misc in the
future.

Strange. I get

E:\>perldoc -q contains
Found in E:\[...]\perlfaq4.pod
How can I tell whether a list or array contains a certain element?
