I wanted to write a PHP
script in which i had to execute INSERT
query in MySQL
database using prepared statement.
As i am a beginner in PHP
, i had no idea how to do it. so I looked it up on Stackoverflow
and found this How to create a secure mysql prepared statement in php? .
So i started doing it in same way as done in the accepted answer BUT in the answer, there are some methods used, like
prepare
to prepare the SELECT
query
bind_param
to bind parameters to query
close
to close to $stmt
which are not suggested to me by Visual Studio Code
when i try to use them. Also when i use these methods and hover the pointer over them, no documentation is shown by the Visual Studio Code
which made me think whether these methods are available anymore or not.
Instead of prepare
method, Visual Studio Code
suggests odbc_prepare
, instead of bind_param
, it suggests mysqli_bind_param
and instead of close
, it suggests odbc_close
.
I am using PHP 7.2
Question: Are methods like prepare
, close
, bind_param
not available in PHP 7
and can i use the ones suggested to me by Visual Studio Code
in place of these methods ?
Those function are not a standalone functions. They are methods of PDO objects. To learn more about PDO check this tutorial: PDO Tutorial
$pdo = new PDO();
$stmt = $pdo->prepare('SELECT * FROM users WHERE email = :email AND status=:status');
$stmt->execute(['email' => $email, 'status' => $status]);
$user = $stmt->fetch();
You can only use these functions without an mysqli
object in the procedural style with the mysqli_
prefix.
The object-orinted style is usually preferred however.
