Array to string conversion is the only way to get access to a useful string in PHP. We luck out that the conversion includes an uppercase A, otherwise we may not be able to get uppercase letters without including other characters.

32 ( ): 1
33 (!): 1
44 (,): 1

The only real way of generating these from alphabetic letters is to use binary operators like ^. For example, we could take advantage of the fact that d^H==',', h^H==' ', and i^H=='!'. This should make it possible to remove these three characters adding only the ^ operator.

Example Random Name Generator

This is a sample project for the nubs/random-name-generator composer package.

Instructions

First, install the dependencies (I created the composer.json file by running composer require nubs/random-name-generator):

composer install

	<?php
	$code = '';

	$code = preg_replace('/^<\?/', '', $code);
	$specialChars = implode('', array_unique(str_split(preg_replace('#[a-z0-9+/]+#i', '', $code))));

	file_put_contents('php://stderr', "Special Characters: " . var_export($specialChars, true) . "\n");
	$unusedChars = implode('', array_diff(
	str_split('abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789/+'),
	array_unique(array_diff(str_split($code), str_split($specialChars)))
