How to compare two 24 hour time

Question

I have two 24-hour time values and want to compare them using PHP.

I have tried the following:

$time="00:05:00"; //5 minutes

if($time1<='00:03:00')
{
 //do some work
}
else
{
 //do something
}

Is this the correct way to compare 2 time values using PHP?

Answer 1

Use the built-in function strtotime():

$time="00:05:00"; //5 minutes
if(strtotime($time)<=strtotime('00:03:00')) {
 //do some work
} else {
 //do something
}

Answer 2

Yes, that is correct. You don't need to convert to an integer because 24-hour format is such that the string value is in the exact same order as the numeric.
