How can PHP developers ensure that their code follows coding standards to prevent errors and improve readability?

To ensure that PHP code follows coding standards, developers can use tools like PHP CodeSniffer to automatically check their code against predefined coding standards such as PSR-1 and PSR-2. This helps prevent errors and inconsistencies in the codebase, making it easier to read and maintain. 

// 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/code

// Sample PHP code that follows PSR-2 coding standards
class MyClass
{
    public function myMethod($param1, $param2)
    {
        if ($param1 === $param2) {
            return true;
        } else {
            return false;
        }
    }
}
