Question

I currently have a date that’s being stored in my SQL database as a VARCHAR of 255 characters. I declared this string as

   //within an object...
   $date = date(DATE_RFC822);

Now, later on in the coding, I realise that I need to actually compare dates with each other. My initial, very naive attempt looked a little bit like this:

if(object_1->date > object_2->date){
 //do this that assumes that object_1 was created at a later date than object_2
}else{
 continue;
}

While this worked fine for different times of the same day; using the code a week later began to show significant bugs.

Answer 1

strtotime() converts a string into unix time (an integer) which can easily be compared with other unix time values. If you are running PHP 5.2.8 or greater, you could also make use of the DateTime class which are relatively easy to compare (see this question for more info)
