CS-213 : Lab 5 : PHP2 part 1 statement
1. WORD FREQUENCY COUNTER:
• Take a text file as input, using file input in HTML on index.php
• Validate that the taken input file is with extension .txt; if it does not have .txt extension, show an error message and redirect it to upload the file again.
• In php, check if (file size less than 2KB), display error otherwise.
• The text file has to be processed to produce the frequency count of (number of occurrences) of each word sorted in alphabetical order as a HTML table
• Frequency count must be case-insensitive (e.g. both ’Hey’ and ’hey’ would be counted under the same word ’hey’)
