Why does this value return true?

Hi All, when running this in php, it returns true.

Which doesn't make sense as 800 is smaller than

Expand|Select|Wrap|Line Numbers

 
    if(0124 >= 0800)

        {

            echo "this doesnt makes sense";    

        }

Not sure why this is the case. However getting rid of the 0 in front fixes it. But I need to keep it as I am comparing time. EG: 0124 is greater than 0800 (8am) etc.

Can someone tells me why PHP behaves this way when you prefix your number with 0?

Many thanks.

If you cast them to an int you wont have this problem.

the problem with the leading 0 is that it will cast the number to octal. i.e. 0124 is converted to 84 and 0800 to 0 (because 8 is not part of the octal system)

EG: 0124 is greater than 0800 (8am) etc.

01:24 AM is greater than 08:00 AM?

if you want to compare dates, use PHP’s date formats (e.g. the UNIX Timestamp or the DateTime classes)

Cheers guys. Type casting it fixed it.

@Dormilich, thanks for the explanation. Never thought hex was in the picture

along with dormilich answer you should also know that if you parse 0 leading number in javascript you will get Octal value
