PHP to calculate the age of accurate to the date of the program

This article mainly introduced the PHP calculation age accurate to year month day the method, involves the PHP operation date and the string correlation skill, very simple practical, needs the friend to be possible to refer to under

This article is an example of how the PHP calculation age is accurate to the date of year. Share to everyone for your reference. Specifically as follows:

$ni) {
$not _birth = 1;
$tmp = Array ($byear, $bmonth, $bday);
List ($byear, $bmonth, $bday) = Array ($year, $month, $day);
List ($year, $month, $day) = $tmp;
List ($bi, $ni) = Array ($ni, $BI);
}
$years = 0;
while (($bi + 10000) <= $ni) {//Age First
$bi + 10000;
$years + +;
$byear + +;
}//get older and leave years behind
List ($m, $d) = $this->getmd (Array ($year, $month, $day), Array ($byear, $bmonth, $bday));
Return Array (' => $years, ' month ' => $m, ' Day ' => $d, ' Not_birth ' => $not _birth);
}

/**
* Can only be used in one year calculation
* @param type $ymd
* @param type $bymd
*/
Public Function Getmd ($YMD, $bymd) {
List ($y, $m, $d) = $ymd;
List ($by, $BM, $bd) = $bymd;
if ($m. $d) < ($BM. $bd)) {
$m +=12;
}
$month = 0;
while (($BM. $bd) + <= ($m. $d)) {
$BM + +;
$month + +;
}
if ($bd <= $d) {//same place one months
$day = $d-$bd;
{//Less one months
$mdays = $BM > 12? $this->_getmothday (+ + $by, $BM -12): $this->_getmothday ($by, $BM);
$day = $mdays-$bd + $d;
}
Return Array ($month, $day);
}

Private Function _getmothday ($year, $month) {
Switch ($month) {
Case 1:
Case 3:
Case 5:
Case 7:
Case 8:
Case 10:
Case 12:
$day = 31;
Break
Case 2:
$day = (intval ($year% 4)? 28:29); Can be removed by 4 for 29 days other 28 days
Break
Default
$day = 30;
Break
}
return $day;
}

}

$cage = New Age ();
