How to Efficiently Fetch COUNT(*) Results in PHP?

Fetching Count Results from SELECT COUNT(*) in PHP

When retrieving row counts for efficiency purposes, it's tempting to utilize the SELECT COUNT(*) query. However, traditional methods involving additional SQL executions can be inefficient. To optimize this process, it's recommended to directly access the count result from SQL instead.

However, note that using reserved words like "count" as column names is not advised. Instead, consider using alternative identifiers such as "cnt."

To obtain the count result in PHP, you can use the following code:

$count = $mysqli->query("SELECT COUNT(*) AS cnt FROM cars")->fetch_object()->cnt;

This approach directly accesses the "cnt" value from the fetched object, providing greater efficiency and code simplicity. Keep in mind the recommendation to avoid using reserved words as column names in your SQL queries for best practices.
