Variable contained in an array

[qwicker]

Hello again:

I have an array with many elements. What would be the most efficient way to check to see if a string is contained somewhere in that array, line by line? I suppose a foreach loop?

perldoc -f grep

you will have to check line by line, or element by element of the array. It might be faster to use a loop and the "last" flow control operator if these are big arrays and you only need to know if the variable is in the array and not how many times it's in the array. grep is fast though and you would have to run checks with your actual data to see which method is better for our situation.
