How to execute stored procedures using PDO in PHP?

To execute stored procedures using PDO in PHP, you can follow these steps:

Connect to the database using PDO:

$servername = "localhost";
$username = "root";
$password = "password";
$dbname = "your_database";

try {
    $conn = new PDO("mysql:host=$servername;dbname=$dbname", $username, $password);
    $conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
    echo "Connected to database successfully";
} catch(PDOException $e) {
    echo "Connection failed: " . $e->getMessage();
}

Prepare the stored procedure using the prepare() method of the PDO object:

$procedureName = 'your_stored_procedure_name';
$parameters = [
    ':param1' => 'value1',
    ':param2' => 'value2',
    // provide parameter values as needed
];

$stmt = $conn->prepare("CALL $procedureName()");

Bind the parameter values (if any) using the bindParam() method:

foreach ($parameters as $parameter => $value) {
    $stmt->bindParam($parameter, $value);
}

Execute the stored procedure using the execute() method:

$stmt->execute();

Fetch the results (if any) using the fetch() or fetchAll() methods:

// Get a single row
$result = $stmt->fetch(PDO::FETCH_ASSOC);

// Get all rows
$results = $stmt->fetchAll(PDO::FETCH_ASSOC);

Close the database connection:

$conn = null;

Note: Make sure to replace the variables ($servername, $username, $password, $dbname) with your actual database connection details, and also update your_stored_procedure_name and the $parameters array with your stored procedure name and relevant parameter values.
