How can PHP developers ensure that their code adheres to proper coding standards and practices recommended by the PHP community?

PHP developers can ensure that their code adheres to proper coding standards and practices recommended by the PHP community by using coding standards tools like PHP CodeSniffer, following the PSR standards, and regularly reviewing their code with peer code reviews. Additionally, using an IDE that supports code formatting and linting can help developers catch and fix coding standard violations before they become a problem.

// Example code snippet using PHP CodeSniffer to check coding standards
// Install PHP CodeSniffer using Composer: composer require squizlabs/php_codesniffer
// Run PHP CodeSniffer on the command line: vendor/bin/phpcs --standard=PSR2 path/to/your/php/files

// Sample PHP code that adheres to PSR-2 coding standards
class SampleClass
{
    public function sampleMethod($param1, $param2 = null)
    {
        if ($param1 === $param2) {
            return true;
        } else {
            return false;
        }
    }
}
