Format number in PHP

I want my number format 12 char in length, like if there is value 12 it should output 000000000012

Example: if value is 123.50 it should output 000000012350 No decimal (multiple of 100)

Any idea, which function will be used?

Thanks !

Answer 1

You can use str_pad

  echo str_pad(12, 12, "0", STR_PAD_LEFT);

You can also use printf or sprintf

  printf("%012s", 12);

Output

000000000012

Some Work Arounds

var_dump(formatOutput("12"));
var_dump(formatOutput("123.50"));
var_dump(formatOutput("123.378201"));


function formatOutput($no,$max = 15) {
    $no = str_pad("1", strlen(substr(strrchr($no, "."), 1)), "0", STR_PAD_RIGHT) * $no;
    if(strpos($no, "."))
        $no = str_replace(".", "", $no) . "0" ;
    return str_pad($no, $max, "0", STR_PAD_LEFT);
}

Output

string '000000000000012' (length=15)
string '000000000001235' (length=15)
string '000001233782010' (length=15)
