PHP if condition based on date not working

Question

I want to execute a if statement where I want if given {date} is less or equal than today then {due_amount}= {paidbystudent} else {due_amount}= '0'

Here is my code:

if ({date} <= Today()) {
    {due_amount}={paidbystudent};
}  else {
    {due_amount}='0';
}

But its not working. Please help me how to do this.

I have also tried this code but its not working properly this is checking only date and ignoring month and year

$todays_date=date("d/m/Y", strtotime("today"));
$date=date("d/m/Y", strtotime({date}));

if ($date <= $todays_date) {
    {due_amount}={paidbystudent};
}  else {
    {due_amount}='0';
}

Start using DateTime class instead of strtotime() using createFromFormat() — Abhik Chakraborty, May 26 '14 at 07:46
Get rid of `date()`. compare the result of `strtotime`. You are telling PHP to compare two strings, PHP doesn't know that they represent dates. — deceze, May 26 '14 at 07:48
Use the format `YYYY-MM-DD` (`Y-m-d`) if you want to compare as strings, though you should just use `new DateTime() <= new DateTime($date)`. — h2ooooooo, May 26 '14 at 07:48
How about you [read the manual](http://www.php.net/manual/en/class.datetime.php) and try it yourself — Bojangles, May 26 '14 at 07:50

How about this:

$date = '2014-05-22'; // fetch from db, user input etc   

if (strtotime($date) <= time()) {
    echo 'paid by student';
} else {
    echo 0;
}

EDIT: As pointed out by deceze, a better way to approach this would be to compare the UNIX timestamp values instead of a date format.

Anti-demo: http://codepad.viper-7.com/dJdyhJ - Comparing the least significant parts first leads to wrong result. – deceze May 26 '14 at 08:02
Aha..wasn't aware of that. So I assume using the `Y-m-d` format is the way to go? – asprin May 26 '14 at 08:04
Just compare `strtotime(...) <= time()`, much more straight forward. – deceze May 26 '14 at 08:05
