Check if timestamp is today

Question

I\'ve got a timestamp in the following format (Which can easily be changed thanks to the beauties of PHP!).

2011-02-12 14:44:00

Answer 1

This is what i use for this kind of task :

/** date comparator restricted by $format.
 @param {int/string/Datetime} $timeA
 @param {int/string/Datetime} $timeB
 @param {string} $format
 @returns : 0 if same. 1 if $timeA before $timeB. -1 if after   */
function compareDates($timeA,$timeB,$format){
    $dateA=$timeA instanceof Datetime?$timeA:(is_numeric($timeA)?(new \Datetime())->setTimestamp($timeA):(new \Datetime("".$timeA)));
    $dateB=$timeB instanceof Datetime?$timeB:(is_numeric($timeB)?(new \Datetime())->setTimestamp($timeB):(new \Datetime("".$timeB)));
    return $dateA->format($format)==$dateB->format($format)?0:($dateA->getTimestamp()<$dateB->getTimestamp()?1:-1);
}

compare day : $format='Y-m-d'.
compare month : $format='Y-m'.
etc...

in your case :

if(compareDates("now",'2011-02-12 14:44:00','Y-m-d')===0){
    // do stuff
}
