What steps can be taken to adapt PHP code for hosting environments that support different PHP versions?

When adapting PHP code for hosting environments that support different PHP versions, it is important to use functions and syntax that are compatible with the lowest supported PHP version. This can involve avoiding newer features or functions that are not available in older PHP versions, and using alternative methods or polyfills to achieve the same functionality across different versions.

// Example of adapting code to support different PHP versions
if (version_compare(PHP_VERSION, '7.0.0', '>=')) {
    // Use newer PHP 7 features
    $result = random_int(1, 10);
} else {
    // Polyfill for random_int function
    $result = mt_rand(1, 10);
}

echo $result;
