Comparing time using PHP

I want to create an attendance system, in which the attendance based on following condition:

// Conditions
define('LATE_COND', '1306566960'); // strtotime(date('09:16:00'))
define('HALF_COND', '1306576860'); // strtotime(date('09:16:00'))  
define('LATE_CODE', '#FC9E4B');
define('HALF_CODE', '#CCFF33');
define('PRESENT', 'PRESENT');
define('LATE', 'LATE');
define('HALF', 'HALF');

$time_in = strtotime(date('h:i:s'));
if($time_in <= LATE_COND){
$day_status = PRESENT;
$color_code = PRESENT_CODE;
}elseif( ($time_in >= LATE_COND) && ($attendance < HALF_COND) ){
$day_status = LATE;
$color_code = LATE_CODE;
}elseif($time_in >= HALF_COND){
$day_status = HALF;
$color_code = HALF_CODE;
}

but for strtotime(date('01:00:00')) value is '130653开发者_开发问答7200' and hence my all condition failed, any help and I want to do it using PHP5.x not mysql

strtotime return epoch time. Which, if you don't already know, is the number of seconds passed since 1970. Now since you seem to be missing the date, as you are including only time, you can include date in it. date('Y-m-d h:i:s'). Hope it helps.
