I can select multiple rows with one condition by using something like: select `col`, `col2` from `table` where `col3` in (?, ?, ?, ?, ?); how can this be done if there are multiple conditions (all integer equals operations)?. The two most common functions for this purpose are mysqli fetch array () and mysqli fetch assoc (). using a while loop in combination with either of these two functions, we can come up with a simple solution to process multiple results to an executed query. In this post, i will tell you how to use mysqli prepared statement to select or fetch multiple rows. as you know very well that by using mysqli prepared statements we make our database query more secure to normal database query.
