Answer 1

In order to enter a values into the DB one must have a connection to the Database.
Create a connection to the relevant database.
Perform our desired query.
Example:
<?php
$con=mysqli_connect("example.com","peter","abc123","my_db");
// Check connection
if (mysqli_connect_errno())
{
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
$sql="INSERT INTO Persons (FirstName, LastName, Age)
VALUES
('$_POST[firstname]','$_POST[lastname]','$_POST[age]')";
if (!mysqli_query($con,$sql))
{
die('Error: ' . mysqli_error($con));
}
echo "1 record added";
mysqli_close($con);
?>
Explanation:
As you can see we first trying to retain a connection using mysqli_connect with the relevant DATABASE-ADDRESS, USERNAME, PASSWORDandDATABASE-NAME`
Than we're using mysqli_query to perform our query and we're passing it the connection we opened earlier + the query string we wish to perform.

Answer 2

you can try this
$sql="INSERT into customer_details(c_id,c_name,c_vehicle_number,c_phone,c_email) VALUES ('".$_POST['value1']."','".$_POST['value1']."','".$_POST['value1']."','".$_POST['value1']."','".$_POST['value1']."')";
you worte :
('','$value2','$value3','$value4','$value5') you did mistake here
it can be write
('".$value2."','".$value3."','".$value4."','".$value5."')
