What are the potential pitfalls of using $_ENV for runtime-specific information in PHP?

Using $_ENV for runtime-specific information in PHP can be risky as it relies on environment variables that can be easily manipulated or changed. This can lead to security vulnerabilities or unexpected behavior in your application. To mitigate this risk, it's recommended to use a more secure method for handling sensitive runtime information, such as storing it in a configuration file or database. 

// Example of storing runtime-specific information in a configuration file

// config.php
return [
    'runtime_info' => [
        'key' => 'value'
    ]
];

// usage.php
$config = include 'config.php';
echo $config['runtime_info']['key'];
