在php中回显两位数

我真的很想通过操纵得到一些数字范围

我的代码目前运行良好，但输出是我的问题所在

我想回应像00/00，00/01之类的东西

但是我的代码给了我0/0，0/1，0/2，等等

我该怎么办

这是我的密码

<?php
 foreach (range(00, 99) as $no2) {
     foreach (range(00, 99) as $no3) {
        echo $no2 . "/" . "$no3</br>";
   }
 }
?>

嗯 后来我做了这样的事情，结果非常好

   <?php
   $no2 = array('01','02','03','04','05','06','07','08','09','10', '11', '12', '13', '14', '15', '16', '17', '18', '19', '20', '21', '22', '23', '24', '25', '26', '27', '28', '29', '30', '31', '32', '33', '34', '35', '36', '37', '38', '39', '40', '41', '42', '43', '44', '45', '46', '47', '48', '49', '50', '51', '52', '53', '54', '55', '56', '57', '58', '59', '60', '61', '62', '63', '64', '65', '66', '67', '68', '69', '70', '71', '72', '73', '74', '75', '76', '77', '78', '79', '80', '81', '82', '83', '84', '85', '86', '87', '88', '89', '90', '91', '92', '93', '94', '95', '96', '97', '98', '99');

  foreach ($no2 as $k ) {
foreach ($no2 as $a) {
 echo "$k" . "/". "$a";
  }

 ?>

查看sprintf：它并没有真正起作用……对我来说……它给我以十位数表示的值，比如02、12、22、32、42等……%02s是以两位数字回送输出。这不是你要找的吗？

   <?php
   $no2 = array('01','02','03','04','05','06','07','08','09','10', '11', '12', '13', '14', '15', '16', '17', '18', '19', '20', '21', '22', '23', '24', '25', '26', '27', '28', '29', '30', '31', '32', '33', '34', '35', '36', '37', '38', '39', '40', '41', '42', '43', '44', '45', '46', '47', '48', '49', '50', '51', '52', '53', '54', '55', '56', '57', '58', '59', '60', '61', '62', '63', '64', '65', '66', '67', '68', '69', '70', '71', '72', '73', '74', '75', '76', '77', '78', '79', '80', '81', '82', '83', '84', '85', '86', '87', '88', '89', '90', '91', '92', '93', '94', '95', '96', '97', '98', '99');

  foreach ($no2 as $k ) {
foreach ($no2 as $a) {
 echo "$k" . "/". "$a";
  }
