generate month leading with zero php

Question

How can I generate month leading with zero like 01-12 .

Here is my code:

<?php for($m = 1;$m <= 12; $m++){ $month =  date("F", mktime(0, 0, 0, $m));?>                               
<li><a href="<?php echo site_url('agenda/'.$tgl[0].'/'.$m);?>"><?php echo $month;?></a></li><?php } ?>  

the output url is still 1-12 . I want it to appear as 01-12 .

Answer 1

use sprintf

<?php echo sprintf('%02d', $month); ?>

in your snippet

<?php for($m = 1;$m <= 12; $m++): ?>    
    <li>
        <a href="<?php echo site_url("agenda/${tgl[0]}/" . sprintf('%02d', $m)); ?>">
            <?php echo date("F", mktime(0, 0, 0, $m)); ?>
        </a>
    </li>
<?php endfor; ?>

Answer 2

how about using str_pad It will pad the string with a character '0' to a length of 2.

<?php 
for($m = 1;$m <= 12; $m++) { 
  $month = str_pad($m, 2, '0', STR_PAD_LEFT);
}
?>

Answer 3

<?php for($m = 1;$m <= 12; $m++){ $month =  date("F", mktime(0, 0, 0, $m)); if ($month < 10) $month = "0".$month; ?>

Answer 4

使用sprintf()可以实现这种格式，

<?php echo sprintf("%02d",$month); ?>

Answer 5

Try with

$month = date('m',mktime(0, 0, 0, $m));  //HERE give 'm' option       

" m " Numeric representation of a month, with leading zeros 01 through 12

Answer 6

又短又快：（sprintf 很贵）

    $month = ($m = date('m')) < 10 ? '0' . $m : $m;
