Are there alternative methods to protect and hide code in PHP besides using DLLs?

One alternative method to protect and hide code in PHP besides using DLLs is by using code obfuscation tools. These tools transform the code into a more complex and less readable form, making it harder for others to understand and modify. Another method is to use PHP encryption libraries to encrypt the code and decrypt it when needed for execution.

// Example of using a PHP obfuscation tool to protect and hide code
// Install an obfuscation tool like PHP Obfuscator
// Run the tool on your PHP code to obfuscate it
// The obfuscated code will be harder to understand and modify
