CREATE TABLE students (
id INT(6) AUTO_INCREMENT PRIMARY KEY,
name VARCHAR(191) NOT NULL,
email VARCHAR(191) NOT NULL,
phone VARCHAR(191) NOT NULL,
course VARCHAR(191) NOT NULL
)
Step 2: Create dbcon.php file and give the database connection as follows:
<?php
$con = mysqli_connect("localhost","root","","blog");
if(!$con){
die('Connection Failed'. mysqli_connect_error());
}
?>
Step 3: Create a file named students.php and paste the below code:
In this file, we will completing CRUD operation using dialog box Bootstrap Modal as given below code.

Step 4: Create code.php file and paste the below code:
In this file, we are writting the code to save data in php mysql.
<?php
require 'dbcon.php';
if(isset($_POST['save_student']))
{
$name = mysqli_real_escape_string($con, $_POST['name']);

$phone = mysqli_real_escape_string($con, $_POST['phone']);
$course = mysqli_real_escape_string($con, $_POST['course']);
if($name == NULL || $email == NULL || $phone == NULL || $course == NULL)
{
$res = [
'status' => 422,
'message' => 'All fields are mandatory'
];
echo json_encode($res);
return;
}
$query = "INSERT INTO students (name,email,phone,course) VALUES ('$name','$email','$phone','$course')";
$query_run = mysqli_query($con, $query);
if($query_run)
{
$res = [
'status' => 200,
'message' => 'Student Created Successfully'
];
echo json_encode($res);
return;
}
else
{
$res = [
'status' => 500,
'message' => 'Student Not Created'
];
echo json_encode($res);
return;
}
}
if(isset($_POST['update_student']))
{

if($name == NULL || $email == NULL || $phone == NULL || $course == NULL)
{
$res = [
'status' => 422,

];
echo json_encode($res);
return;
}
$query = "UPDATE students SET name='$name', email='$email', phone='$phone', course='$course'
WHERE id='$student_id'";
$query_run = mysqli_query($con, $query);
if($query_run)
{
$res = [
'status' => 200,

];
echo json_encode($res);
return;
}
else
{

'data' => $student
];
echo json_encode($res);
return;
}
else
{

'status' => 404,

];
echo json_encode($res);
return;
}
}
if(isset($_POST['delete_student']))
{
$student_id = mysqli_real_escape_string($con, $_POST['student_id']);
