Reading File Lines

I need to search a text file that has a name then a number for each line,  and I need to find the whole line by just the name. I'm kinda new to AutoIT but know a lot of PHP web programming, but it seems like there functions are completely different.

Example

Text File

Bob 8
Jack 4
Joey 22
Matt 18
Bill 48

Input

Joey

Expected Output

                 (Or in an array)

          Joey 22
