PHP mysqli_fetch_row() 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_fetch_row() Function.

The mysqli_fetch_row() function accepts a result object as a parameter, and retrieves the contents of it's current row as an array of strings.

Following below is the syntax to use this function -

mysqli_fetch_row($result);


Parameter Details

Sr.NoParameter & Description

Return Value

This built-in PHP function returns an array (string) containing the values in the row to which the data seek is currently pointed.

PHP Version

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

Example1

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

<?php
   $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', 'Douglas', 'Texas', 'UnitedStates')");
   print("Record Inserted.....\n");

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

   while ($row = mysqli_fetch_row($res)) {
      print("ID: ".$row[0]."\n");
      print("First_Name: ".$row[1]."\n");
      print("Last_Name: ".$row[2]."\n");
      print("Place_Of_Birth: ".$row[3]."\n");
      print("Country: ".$row[4]."\n");
   }

   //Closing the statement
   mysqli_free_result($res);

   //Closing the connection
   mysqli_close($con);
?>

Output

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

Table Created.....
Record Inserted.....
ID: 1
First_Name: Kennedy
Last_Name: Nkpara
Place_Of_Birth: PortHarcourt
Country: Nigeria
ID: 2
First_Name: Jonathan
Last_Name: Trott
Place_Of_Birth: CapeTown
Country: SouthAfrica
ID: 3
First_Name: Queen
Last_Name: Douglas
Place_Of_Birth: Texas
Country: UnitedStates

Example2

In an object oriented style the syntax of this function is $result->fetch_row(); Following is the example of this function in an object oriented style -

<?php
   //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),('Prince', 28),('Stephanie', 24)");

   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 = 'Prince';
   $name4 = 'Stephanie';

   //Executing the statement
   $stmt->execute();

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


   //Fetching the contents of all the row
   while ($row = $res->fetch_row()) {
      print("Name: ".$row[0]."\n");
      print("Age: ".$row[1]."\n");
      print("\n");
   }

   //Closing the statement
   $stmt->close();

   //Closing the connection
   $con->close();
?>

Output

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

Table Created.....
Name: Kennedy
Age: 27

Name: Paul
Age: 30

Name: Prince
Age: 28

Name: Stephanie
Age: 24
