# Convert variables

I'm trying calculate time between dates(with mktime).

\$dateDiff = mktime(16,33,00,11,11,2004) - mktime(16,30,44,11,11,2004);
echo 'Difference in seconds: ' . \$dateDiff . '<br />';

echo '<br />Years Difference   = '. floor(\$dateDiff/365/60/60/24);
echo '<br />Months Difference  = '. floor(\$dateDiff/60/60/24/7/4);
echo '<br />Weeks Difference   = '. floor(\$dateDiff/60/60/24/7);
echo '<br />Days Difference    = '. floor(\$dateDiff/60/60/24);
echo '<br />Hours Difference   = '. floor(\$dateDiff/60/60);
echo '<br />Minutes Difference = '. floor(\$dateDiff/60);

The problem is, if i save the information: 16,33,00,11,11,2004 in the MsSQL Data Base in a char field when i get it to put inside the mktime like:

\$TimeStamp = '16,30,44,11,11,2004';
mktime(\$TimeStamp)

it doesn't work... mabe i should split like this:

list(\$Hour, \$Minutes, \$Seconds, \$Months, \$Day, \$Year) = split('[,]', \$TimeStamp);

and then convert them to integer... Can anyone help me?

If you have that format, use the method you described. You don't need to convert them to integer (this will be done by PHP) and then use those variables in mktime like this:
mktime(\$Hour, \$Minutes, \$Seconds, \$Months, \$Day, \$Year);
There are a lot of other way, but they willl end up in such function call.

If you are going to do it with list i would use explode instead, split uses regular expressions and is more then is needed here:

list(\$Hour, \$Minutes, \$Seconds, \$Months, \$Day, \$Year) = explode(",", \$TimeStamp);
