Re: Function to check a valid date

Your likely to find many ways to do this and many functions with many lines of code that do many variations of what you want. Can I use the word "many" many more times? Such is the way with programming. Here's my take on it. Pull all your values into one long string: $date_string = "{$_POST["week_day"]}, {$_POST["month"]} {$_POST["day"]}, {$_POST["year"]}"; Now, you have a string in the format "Saturday, March 20, 2004". Now, use strtotime() to figure out whether it's a valid date: if (($timestamp = strtotime($date_string)) === -1) {

    // Not a valid date; do some error reporting here

} else {

    // It is a valid date, $timestamp is now a valid Unix
    // timestamp of $date_string; use it like below:
    echo date("m/d/Y", $timestamp);

Hello all, I was going to build a function to check whether a selected date exists, but thought that I would see if anyone has done this type of thing already which would indeed save me some time. I have a form where the users select the day of the week, month, date and year from 4 pulldowns. (Saturday, March 20, 2004). I need to have a function that will check to see if that is indeed a real date. Does this sound familiar to anyone?
