# str_pad

(PHP 4 >= 4.0.1, PHP 5)

str_pad -- Pad a string to a certain length with another string

## Description

string str_pad ( string input, int pad_length [, string pad_string [, int pad_type]] )

This functions returns the `input` string padded on the left, the right, or both sides to the specified padding length. If the optional argument `pad_string` is not supplied, the `input` is padded with spaces, otherwise it is padded with characters from `pad_string` up to the limit.

Optional argument `pad_type` can be `STR_PAD_RIGHT`, `STR_PAD_LEFT`, or `STR_PAD_BOTH`. If `pad_type` is not specified it is assumed to be `STR_PAD_RIGHT`.

If the value of `pad_length` is negative or less than the length of the input string, no padding takes place.

Przykład 1. str_pad() example

`<?php $input = "Alien"; echo str_pad($input, 10); // produces "Alien " echo str_pad($input, 10, "-=", STR_PAD_LEFT); // produces "-=-=-Alien" echo str_pad($input, 10, "_", STR_PAD_BOTH); // produces "__Alien___" echo str_pad($input, 6 , "___"); // produces "Alien_" ?>`

> Notatka: The `pad_string` may be truncated if the required number of padding characters can't be evenly divided by the `pad_string`'s length.
