How can Apache be properly started and configured to avoid browser not found errors when working with PHP files?

When working with PHP files in Apache, browser not found errors can occur if the server is not properly started or configured. To avoid this issue, ensure that Apache is running and that the PHP module is enabled in the server configuration file. Additionally, make sure that the file paths in your PHP code are correct and that the files are located in the correct directory.

<?php
// Sample PHP code to check if Apache is properly configured
if (function_exists('apache_get_modules')) {
    $modules = apache_get_modules();
    if (in_array('php5_module', $modules) || in_array('php7_module', $modules)) {
        echo 'PHP module is enabled in Apache configuration.';
    } else {
        echo 'PHP module is not enabled in Apache configuration.';
    }
} else {
    echo 'Unable to check Apache modules.';
}
?>
