Reading Data From a File

• Now that you have written to a file, you might as well read some data back.
• Not always: you might just want to generate HTML, or you might send an e-mail.
• To do so,
• Open the file witn <,
• Read each line into an array with the syntax @array = <filehandle>
• Close the file,
• Do something with the resulting array.
open(DATA, "<../userdata.txt") || &error;
@dataFromFile = <DATA>;
close(DATA);
