这是我的代码：
$curr_year = date('Y');
$dob_year = rand($curr_year-18,$curr_year-47);
$dob_month = rand(01,12);
$dob_day = rand(01,30);
echo $dob = $dob_month.'/'.$dob_day.'/'.$dob_year;
我的结果是1/2/1988,但我的要求是结果应该是01/02/1988
使用
str_pad.
echo $dob = str_pad($dob_month,2,'0',STR_PAD_LEFT) . '/' . str_pad($dob_day,STR_PAD_LEFT) . '/'.$dob_year;
