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 built-in PHP mysqli_fetch_all() 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");

   //Fetching all the rows of the result
   $rows = mysqli_fetch_all($res);
   print_r($rows);

   //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.....
Array
(
    [0] => Array
        (
            [0] => 1
            [1] => Kennedy
            [2] => Nkpara
            [3] => PortHarcourt
            [4] => Nigeria
        )
    [1] => Array
        (
            [0] => 2
            [1] => Jonathan
            [2] => Trott
            [3] => CapeTown
            [4] => SouthAfrica
        )

    [2] => Array
        (
            [0] => 3
            [1] => Queen
            [2] => Douglas
            [3] => Texas
            [4] => UnitedStates
        )
)

Example2

In an object oriented style the syntax of this function is $result->fetch_all(); The following is an 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)");
   print("Table Created.....\n");

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

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

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

   //Fetching all the rows
   $rows = $result->fetch_all();
   print_r($rows);

   //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.....
Array
(
    [0] => Array
        (
            [0] => Kennedy
            [1] => 27
        )

    [1] => Array
        (
            [0] => Paul
            [1] => 30
        )

)
