Snippets

Snippet Library

Practical pure PHP patterns that are easy to study, adapt and use.

Code

URL Encode and Decode

Encodes a route segment with rawurlencode(), decodes it safely, and builds a query string with http_build_query().

Code

Define and Use a Constant

Defines a PHP constant only when it is not already defined, then uses it in a small configuration calculation.

Open Snippet

Code

Include and Require Files

Demonstrates allowlisted include/require loading so a caller can load an approved PHP file without accepting arbitrary paths.

Open Snippet

Code

Check if a Function Exists

Checks whether a PHP function exists, restricts callable execution to an allowlist, and optionally runs the approved function.

Open Snippet

Code

Check if a Class Exists

Checks a requested PHP class name with class_exists() and returns a safe status array without triggering autoloader surprises unless explicitly allowed.

Returns the public methods available on an existing PHP class name after confirming the class exists.

Code

Composition Pattern Without Inheritance

Composes one result array from independent ship, crew, and mission arrays instead of using inheritance or parent classes.

Code

Configuration Constants Without Static Classes

Defines and reads prefixed procedural constants for configuration without using static classes.

Open Snippet

Code

Interface Contract Array Without Abstract Classes

Validates an associative array against a required field contract without abstract classes or inheritance.

Open Snippet
