Formatting a number with leading zeros in PHP

Use sprintf :

sprintf('%08d', 1234567);

Alternatively you can also use str_pad:

str_pad($value, 8, '0', STR_PAD_LEFT);

Given that the value is in $value:

• To echo it:

  printf("%08d", $value);

• To get it:

  $formatted_value = sprintf("%08d", $value);

That should do the trick

When I need 01 instead of 1, the following worked for me:

$number = 1;
$number = str_pad($number, 2, '0', STR_PAD_LEFT);
