Checkdate in PHP
PHP checkdate() is a useful built-in function, which accepts a month, day, and year (mm/dd/yyyy) combination and returns a true/false value indicating whether the corresponding date is valid.
<?php
if(checkdate(2, 13, 2022))
echo 'Date is valid';
else
echo 'Date is invalid';
echo "<br/>";
if(checkdate(2, 30, 2022))
echo 'Date is valid';
else
echo 'Date is invalid';
?>
Output:
Here, we check whether the date is valid or not using the PHP check date () function. It returns true, if the given date is valid otherwise it returns false.
