The key is to look at the value of the submit button. This needs to be unique.
Change around your logic a little and you will have it.
<?php
// if form not yet submitted
// display form
if ( isset($_POST['submit']) && $_POST['submit'] === 'Submit' ) {
// process form input
// split date value into components
$dateArr = explode('/', $_POST['dob']);
// calculate timestamp corresponding to date value
$dateTs = strtotime($_POST['dob']);
// calculate timestamp corresponding to 'today'
$now = strtotime('today');
// check that the value entered is in the correct format
if ( sizeof($dateArr) != 3 ) {
die('ERROR: Please enter a valid date of birth');
}
// check that the value entered is a valid date
if ( !checkdate($dateArr[0], $dateArr[1], $dateArr[2]) ) {
die('ERROR: Please enter a valid date of birth');
}
// check that the date entered is earlier than 'today'
if ( $dateTs >= $now ) {
die('ERROR: Please enter a date of birth earlier than today');
}
// calculate difference between date of birth and today in days
// convert to years
// convert remaining days to months
// print output
$ageDays = floor(($now - $dateTs) / 86400);
$ageYears = floor($ageDays / 365);
$ageMonths = floor(($ageDays - ($ageYears * 365)) / 30);
echo "You are approximately $ageYears years and $ageMonths months old.";
} else if ( isset($_POST['submit']) && $_POST['submit'] === 'Submit Kitten' ) {
$name_cat = $_POST['cat'];
echo "Your Kitten is $name_cat";
} else {
echo <<<HTML
<form method="post" action="agecalc3.php">
Enter your date of birth, in mm/dd/yyyy format: <br />
<input type="text" name="dob" />
<input type="submit" name="submit" value="Submit" />
</form>
<br /><br />
<form method="post" action="agecalc3.php">
