PHP Best Practices

Principles and rules

All code must follow:

• Clean Code by Uncle Bob.
• DRY, KISS and SOLID.
• Continuous refactor. If you edit a method clean it: Boy scout rule.

<?php
/**
 * simple method to encrypt or decrypt a plain text string
 * initialization vector(IV) has to be the same when encrypting and decrypting
 * 
 * @param string $action: can be 'encrypt' or 'decrypt'
 * @param string $string: string to encrypt or decrypt
 *
 * @return string
 */

<?php

print "<h1>PHP Encryption with libsodium</h1>";

$message    = "This text is secret";
$ciphertext = cryptor::encrypt("password", $message);
$plaintext  = cryptor::decrypt("password", $ciphertext);

print "Message:<br />$message <br /><br />Ciphertext:<br />$ciphertext<br /><br />Plaintext:<br />$plaintext";

NGINX Tuning For Best Performance

For this configuration you can use web server you like, i decided, because i work mostly with it to use nginx.

Generally, properly configured nginx can handle up to 400K to 500K requests per second (clustered), most what i saw is 50K to 80K (non-clustered) requests per second and 30% CPU load, course, this was 2 x Intel Xeon with HyperThreading enabled, but it can work without problem on slower machines.

You must understand that this config is used in testing environment and not in production so you will need to find a way to implement most of those features best possible for your servers.
