Example

Following example demonstrates the usage of the mysqli_fetch_assoc() function (in 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, 'Sikhar', 'Dhawan', 'Delhi', 'India')");
   mysqli_query($con, "INSERT INTO myplayers values(2, 'Jonathan', 'Trott', 'CapeTown', 'SouthAfrica')");
   mysqli_query($con, "INSERT INTO myplayers values(3, 'Kumara', 'Sangakkara', 'Matale', 'Srilanka')");
   print("Record Inserted.....\n");

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

   //Fetching all the rows as objects
   while($obj = mysqli_fetch_assoc($res)){
      print("ID: ".$obj["ID"]."\n");
      print("First_Name: ".$obj["First_Name"]."\n");
      print("Last_Name: ".$obj["Last_Name"]."\n");
      print("Place_Of_Birth: ".$obj["Place_Of_Birth"]."\n");
      print("Country: ".$obj["Country"]."\n");
   }
   //Closing the statement
   mysqli_free_result($res);

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

This will produce following result −

Table Created.....
Record Inserted.....

<?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('Raju', 25),('Rahman', 30),('Sarmista', 27)");
   print("Table Created.....\n");

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

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

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

   //Fetching all the rows as arrays
   while($obj = $result->fetch_assoc()){	
      print("Name: ".$obj["Name"]."\n");
      print("Age: ".$obj["Age"]."\n");
   }

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

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

This will produce following result −

Table Created.....
Name: Raju
Age: 25
Name: Rahman
Age: 30
