<p><h2>How to Efficiently Use mysql_fetch_array in Loops to Handle Massive Data?</h2></p>
<p><p>When working with MySQL databases in PHP, a common requirement is to read large volumes of data in bulk. mysql_fetch_array is a frequently used function that retrieves rows from the query result set one by one, making it convenient for loop-based processing. However, if not used properly or optimized, handling huge datasets may cause memory overflow, performance lags, or even crashes. This article introduces several techniques to help you efficiently use mysql_fetch_array in loops.</p></p>
<p><h3></span>1<span>. Avoid Loading All Data at Once</h3><br>
<p>Many beginners tend to use <code>SELECT * FROM table

By processing data in batches, you can prevent loading too much data at once, thereby improving the stability and performance of the script.

Conclusion

The key to efficiently using mysql_fetch_array in loops lies in controlling the size of each batch of data, selecting the right array type, releasing resources in time, and combining these with proper database operation strategies. Whenever possible, switch to MySQLi or PDO instead of the outdated mysql extension to ensure maintainability and better performance. Mastering these techniques will allow you to handle massive datasets with ease.
