What are some best practices for optimizing PHP scripts to avoid exceeding CPU-Usage-Time limits on hosting platforms?

Exceeding CPU-Usage-Time limits on hosting platforms can be avoided by optimizing PHP scripts. One way to do this is by minimizing the use of loops, optimizing database queries, and caching data where possible. Additionally, using efficient algorithms and avoiding unnecessary computations can also help reduce CPU usage. 

// Example of optimizing PHP script to avoid exceeding CPU-Usage-Time limits

// Avoid unnecessary loops
$sum = 0;
for ($i = 1; $i <= 1000; $i++) {
    $sum += $i;
}

// Optimize database queries
$query = "SELECT * FROM users WHERE status = 'active'";
$result = $db->query($query);

// Cache data where possible
$cacheKey = 'users_data';
if (!$data = $cache->get($cacheKey)) {
    $data = fetchDataFromDatabase();
    $cache->set($cacheKey, $data, 3600);
}

// Use efficient algorithms
function fibonacci($n) {
    if ($n <= 1) {
        return $n;
    } else {
        return fibonacci($n - 1) + fibonacci($n - 2);
    }
}
$number = 10;
echo fibonacci($number);
