Answer 1

The problem is related to a change in how PHP computes time from 4.x to 5.x



If you used the format yyyy-mm-dd you would get the result you expect in 4.x; e.g., 2006-02-12.

Answer 2

This is not a bug in PHP but there are certain rules that strtotime still follows. The date that you specified is not considered a valid date format.



If you can edit your date format, then you will have to change it into something like these:

$str = '12/02/2006'; // format #1

$str = '2006-12-02'; // format #2



If you can't then you can try this:



$str = "12-02-2006";

if (preg_match('%(0[1-9]|1[012])[- /.](0[1-9]|[12][0-9]|3[01])[- /.](19|20[0-9]{2})%', $str, $regs)) {

$month = $regs[1];

$day = $regs[2];

$year = $regs[3];

echo "$str == " . date('l dS \o\f F Y h:i:s A', mktime(0,0,0,$month,$day,$year));

} else {

echo "invalid date format?";

}

strtotime Example 2. Checking for failure




$str = 'Not Good';



// previous to PHP 5.1.0 you would compare with -1, instead of false

if (($timestamp = strtotime($str)) === false) {

echo "The string ($str) is bogus";

} else {

echo "$str == " . date('l dS \o\f F Y h:i:s A', $timestamp);

}

?>



NOTE the line

----> // previous to PHP 5.1.0 you would compare with -1, instead of false
