how can I make a conditional statement like if date("Y-m-d h:i:s"); is more than 30 seconds after date("Y-m-d h:i:s");.
I've previously used something like date("Y-m-d h:i:s"); < date("Y-m-d h:i:s"); + 30, however this doesn't seem to work.
Help?
Use strtotime() to convert them to UNIX time.
E.g.:
if(strtotime($date2) - strtotime($date1) > 30) {
// $date2 is more than 30 seconds after $date1
}
or
if(abs(strtotime($date2) - strtotime($date1)) > 30) {
// $dates are more than 30 second apart
}
Use unixtime, instead. Just convert your date("Y-m-d h:i:s"); to date("U") or just time(). strototime() could help you with this. It shows the time in seconds since the Unix Epoch (January 1 1970 00:00:00 GMT). Then this method $unixtime + 30 will work fine as well ;)
Use strtotime() to convert both dates to a unix timestamp, then add the wanted amount of seconds to the second and do an integer comparison.
It looks like you are trying to compare database date fields (like mysql DATETIME). Use the database systems date and time functions to compare date values (like DATE_ADD() or + and with simple < or > in MySQL).
