How to make Base64 encoding and decoding safe?

base64 and the PHP manual

string base64_encode ( string data )
base64_encode() returns data encoded with base64.
This encoding is designed to make binary data survive transport through transport layers that are not 8-bit clean, such as mail bodies.
Base64-encoded data takes about 33% more space than the original data.

Example 1. base64_encode() example

<?php
$str = 'This is an encoded string';
echo base64_encode($str);
?>  

This example will produce:

The MySQL Connection Manager for classic (no-ORM) queries

Singleton And Connection Manager

Singleton: one class that (via itself) creates one and only one instance (of itself) if that instance was not created before, and always returns that instance.

ConnectionManager: Class that acts as a a set of singletons, so it creates for each database account one and only one singleton.

The default database account in CakePHP is ‘default’ and it is is of type mysql.

Since most of PHP developers are fans of MySQL (both the mysql and mysqli extensions), I created the class below, to show you how to integrate your old Mysql Connection Manager into the CakePHP framework.

The Include Engine

Include Engine Features

 

The FileEngine is currently the default cache engine in CakePHP.

In this article I will change the behavior of the FileEngine caching class by sub-classing it to make it able to do the following:

1. Creates/reads a cached PHP file (real PHP file) that stores one more variable(s).
2. Although IncludeEngine is used for temporary caching (by default), however, adding the key ‘forever’ => true in its configuration will make this cached version “permanent” so the date-time checking is skipped
3. The ‘serialize’ key of the configuration is still true by default, and is still recommend (more secure and even faster!) for any non-resource data type variable (int, float, string, boolean, array, object). However, you may ask the IncludeEngine to create a human readable (in our case non serialized) cached version of the variables you want to store (cache). So setting the ‘serialize’ key of the configuration to false is secure for just scalar variables and scalar arrays (int, float string, boolean and arrays that are based on primitive scalar data type
