Using Laravel for Advanced String Manipulation in PHP

Padding the End of Strings

Explore using Laravel's padRight helper method to add padding characters at the end of strings. Understand how to handle fixed-length formatting with practical examples, and learn to simplify padding complexity by combining Laravel helpers with PHP's number_format function for cleaner code.

We'll cover the following...

The padRight helper method

We can use the padRight helper method to add padding characters to the end of a string up to a specific length.

PHP
<?php
/**
 * Versions: Laravel 8, 9
 *
 * @return string
 */
public static function padRight(
    string $value,
       int $length,
    string $pad = ' '
);

This method is beneficial in ensuring a value takes up a fixed amount of space. For example, the following example will ensure that the input strings always take up at least fifteen characters:

PHP
<?php
use Illuminate\Support\Str;
// Returns "Desk           "
Str::padRight('Desk', 15);
// Returns "Lamp           "
Str::padRight('Lamp', 15);
// Returns "Office Printer "
Str::padRight('Office Printer', 15);
