PHP MySql Delete

using PHP, we can delete the record from a database table in just 3 steps.

Firstly make a connection, write sql delete query and execute it.

<?php
    $conn = mysqli_connect("localhost", "root" , "", "student");
	
    if($conn === false){
        die("ERROR: Could not connect to database.");
    }
    
    $sql = "delete from book where Id=0";
    $result = mysqli_query($conn, $sql);
    
    if($result==1)
        echo "Record Deleted";
    else
        echo "error";
    
    mysqli_close($conn);
?>
