PHP mysqli_data_seek() Function

Hello folks! welcome back to a new edition of our tutorial on PHP. In this tutorial guide, we are going to be studying about the PHP mysqli_data_seek() Function.

The built-in PHP mysqli_data_seek() function accepts a result object and an integer value representing an offset, as parameters, and moves the data seek of the given result object to the specified row.


Following below is the syntax to use this function -

mysqli_data_seek($result, $offset);

Parameter Details

Sr.NoParameter & Description


This is an identifier representing a result object.



This is an integer value representing an offset to which you need to move the data seek in the given result object.

Return Value

This built-in PHP function returns true on success and false on failure.

PHP Version

This PHP function was first introduced in PHP version 5 and works in all the later versions.


The following below is an example which demonstrates the usage of the built-in PHP mysqli_data_seek() function (in a procedural style) -

   $con = mysqli_connect("localhost", "root", "password", "mydb");

   mysqli_query($con, "CREATE TABLE myplayers(ID INT, First_Name VARCHAR(255), Last_Name VARCHAR(255), Place_Of_Birth VARCHAR(255), Country VARCHAR(255))");
   print("Table Created.....\n");
   mysqli_query($con, "INSERT INTO myplayers values(1, 'Kennedy', 'Nkpara', 'PortHarcourt', 'Nigeria')");
   mysqli_query($con, "INSERT INTO myplayers values(2, 'Jonathan', 'Trott', 'CapeTown', 'SouthAfrica')");
   mysqli_query($con, "INSERT INTO myplayers values(3, 'Queen', 'Dauglas', 'Texas', 'UnitedStates')");
   print("Record Inserted.....\n");

   //Retrieving the contents of the table
   $res = mysqli_query($con, "SELECT * FROM myplayers");

   //Seek to 2nd row
   mysqli_data_seek($res, 1);

   //Fetching the contents of the row
   $row = mysqli_fetch_row($res);

   //Closing the statement

   //Closing the connection


When the above code is executed, it will produce the following result -

Table Created.....
Record Inserted.....
    [0] => 2
    [1] => Jonathan
    [2] => Trott
    [3] => CapeTown
    [4] => SouthAfrica


In an object oriented style the syntax of this PHP function is $result->data_seek(); The following is the example of this function in an object oriented style -

   //Creating a connection
   $con = new mysqli("localhost", "root", "password", "mydb");

   $con -> query("CREATE TABLE Test(Name VARCHAR(255), AGE INT)");
   $con -> query("insert into Test values('Kennedy', 27),('Paul', 30),('Justice', 28)");
   $con -> query("insert into Test values('Precious', 25),('Stephanie', 24),('Bethel', 27)");

   print("Table Created.....\n");

   $stmt = $con -> prepare( "SELECT * FROM Test WHERE Name in(?, ?, ?, ?)");
   $stmt -> bind_param("ssss", $name1, $name2, $name3, $name4);
   $name1 = 'Kennedy';
   $name2 = 'Paul';
   $name3 = 'Stephanie';
   $name4 = 'Bethel';

   //Executing the statement

   //Retrieving the result
   $res = $stmt->get_result();

   //Seek to 3rd row

   //Fetching the contents of the row
   $row = $res->fetch_row();

   //Closing the statement

   //Closing the connection


When the above code is executed, it will produce the following result -

Table Created.....
    [0] => Stephanie
    [1] => 24
