Topic: Date Validations in PHP
Read some information on date validating (isdate, checkdate, strtotime, etc...), but which is the best way to do date validating for the following:
The start and end dates will be specified from month, day, and year drop-down menus.
Validate that start date and end date are valid dates.
Validate that start date is greater than or equal to today.
Validate that end date is greater than or equal to start date.
Then what is the syntax to convert these dates (mm/dd/yyyy) to unix timestamp?
