Perl/PHP save form to text file

Need a perl/php script that will save form results to a text file on a Linux server. The server runs both these cgi's. The form has about 10 entries, 1 is a comment field, 2 are checkboxes, and the rest are text fields. The form should save fields separated by commas, 1 submission per line. The script needs to convert the any form submitted commas to some other character (like ";"). NEED THIS ASAP. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Installation package that will install the software (in ready-to-run condition) on the platform(s) specified in this bid request. 3) Complete ownership and distribution copyrights to all work purchased. ## Platform Linux / Apache server ## Deadline information FAST (LIKE TODAY)
