What are some potential pitfalls to consider when creating an installer for a PHP application?

One potential pitfall to consider when creating an installer for a PHP application is ensuring that the installer is compatible with different operating systems and environments. To address this, you can use conditional statements to check for the operating system and environment before executing specific installation steps.

if (strtoupper(substr(PHP_OS, 0, 3)) === 'WIN') {
    // Windows-specific installation steps
} elseif (PHP_OS === 'Linux') {
    // Linux-specific installation steps
} else {
    // Default installation steps
}
