Some web applications are needed to show the age of the user. In that case, you need to calculate the user age from date of birth. Here we’ll provide a short PHP code snippet to calculate age from date of birth.
In the following code,
date_diff() functions are used to calculate age of the user till today in PHP.
$dateOfBirth = "17-10-1985";
$today = date("Y-m-d");
$diff = date_diff(date_create($dateOfBirth), date_create($today));
echo 'Age is '.$diff->format('%y');
