str_pad() function pads string to length pad_length with a specified characters

 
Its syntax is: string str_pad (string input, int pad_length [, string pad_string [, int pad_type]])
If pad_string is not specified, string will be padded with blank spaces. 
pad_type may be assigned STR_PAD_RIGHT, STR_PAD_LEFT, or STR_PAD_BOTH
This example shows how to pad a string using str_pad() defaults:
<?
$food = "salad";
print str_pad ($food, 5);    
?>

STR_PAD_LEFT, STR_PAD_RIGHT, or STR_PAD_BOTH:

 
<?
    $string = "Goodbye, Perl!";
    $a = str_pad($string, 10, "-", STR_PAD_LEFT);
    $b = str_pad($string, 10, "-", STR_PAD_RIGHT);
    $c = str_pad($string, 10, "-", STR_PAD_BOTH);
?>

str_pad.php

 
<?php
   echo str_pad("Salad", 10)." is good.";
?>

There is an optional third parameter to str_pad( ) that lets you set the padding character to use

 
<?
    $string = "Goodbye, Perl!";
    $newstring = str_pad($string, 10, "a");
?>

<?php
printf("Space padding can be tricky in HTML % 5d.", 42);
?>

Using left zero padding

 
<?php
printf("Zero padding can help alignment %05d.", 42);
?>
