本文实例讲述了php根据生日计算年龄的方法。分享给大家供大家参考。具体如下:
<?php function birthday($birthday){ $age = strtotime($birthday); if($age === false){ return false; } list($y1,$m1,$d1) = explode("-",date("Y-m-d",$age)); $now = strtotime("now"); list($y2,$m2,$d2) = explode("-",date("Y-m-d",$now)); $age = $y2 - $y1; if((int)($m2.$d2) < (int)($m1.$d1)) $age -= 1; return $age; } echo birthday('1986-07-22'); ?>
再来个简单点的,感觉没有上面的高大上
<?php echo birthday("1989-01-25"); function birthday2($birthday){ list($year,$month,$day) = explode("-",$birthday); $year_diff = date("Y") - $year; $month_diff = date("m") - $month; $day_diff = date("d") - $day; if ($day_diff < 0 || $month_diff < 0) $year_diff--; return $year_diff; }
希望本文所述对大家的php程序设计有所帮助。
