Verify Age Limit With PHP Datetime
This small script shows how to check a person is of a given age. Buy using the PHP DateTime class, php is able to account for dates at a system level.
<?php/**
*
* Check minimum age. Defaults to 18 years
*
*/function validate_age( $dob, $min_age=18 ){
$dob = new DateTime( $dob );
$min_age = new DateTime( 'now - ' . $min_age . 'years' );
return $dob <= $min_age;
}// the person must be at least 21 years of age$age = 21;// persons date of birth (dd-mm-yyyy)$dob = '20-4-1981';
if( validate_age( $dob, $age ) === false ){
echo 'Person is not 21 years old';
}else{
echo 'Person is 21 or over';
}?>
