What is PhpDig?
PhpDig is a PHP MySQL based
Web Spider & Search Engine.



mcal_time_valid — Returns TRUE if the time is a valid time


bool mcal_time_valid(hour, min, sec);
int hour: The hour of the time to check
int min: The minutes of the time to check
int sec: The seconds of the time to check


TRUE if the time is valid, FALSE if it is not


mcal_time_valid() lets you check to make sure that a time actually exists. This can be important as many of PHP's date functions will just wrap around if you pass them times that are out of range, such as 70 minutes.


PHP 3 since 3.0.13, PHP 4 since 4.0b4


Example 733. Checking if a time is valid

$hour = 14;
$minutes = 30;
$seconds = 200;

if (mcal_time_valid($hour, $minutes, $seconds)) {
    echo "The time is valid";
} else {
    echo "The time is invalid";
