In this article, we will focus on the mysqli_field_seek() function in PHP, which is used to set the field cursor to the specified field offset. We will provide you with an overview of the function, how it works, and examples of its use.

Introduction to the mysqli_field_seek() function

The mysqli_field_seek() function is a built-in function in PHP that is used to set the field cursor to the specified field offset in a MySQLi result set. This function is useful when you need to access a specific column in a result set by its offset.

How to use the mysqli_field_seek() function

Using the mysqli_field_seek() function is very simple. You just need to call the function on a valid MySQLi result set and specify the field offset you want to set the field cursor to. Here is an example:

$mysqli = mysqli_connect("localhost", "username", "password", "database");

$query = "SELECT * FROM my_table";
$result = mysqli_query($mysqli, $query);

mysqli_field_seek($result, 2);
$field_info = mysqli_fetch_field($result);
printf("Field name: %s\n", $field_info->name);


In this example, we call the mysqli_connect() function to connect to a MySQL database with a username and password. We then execute a query using the mysqli_query() function to select all columns from a table. We store the result in a variable and call the mysqli_field_seek() function on the result set to set the field cursor to the third field offset. We then call the mysqli_fetch_field() function to get information about the current field, and output the name of the field using the printf() function.


In conclusion, the mysqli_field_seek() function is a useful tool for setting the field cursor to the specified field offset in a MySQLi result set. By understanding how to use the function, you can take advantage of this feature to create powerful and flexible MySQLi queries.
