How can a PDF file stored in a varbinary(max) column in an MS SQL Server be displayed using PHP?

To display a PDF file stored in a varbinary(max) column in an MS SQL Server using PHP, you will need to retrieve the binary data from the database and then output it as a PDF file to the browser. You can achieve this by using the appropriate headers to specify the content type as application/pdf and then echoing the binary data.

<?php
// Connect to the database
$serverName = "your_server_name";
$connectionOptions = array(
    "Database" => "your_database",
    "Uid" => "your_username",
    "PWD" => "your_password"
);
$conn = sqlsrv_connect($serverName, $connectionOptions);

// Retrieve the binary data from the database
$sql = "SELECT pdf_data FROM your_table WHERE id = ?";
$params = array($your_id);
$stmt = sqlsrv_query($conn, $sql, $params);
$row = sqlsrv_fetch_array($stmt);

// Output the PDF file
header("Content-type: application/pdf");
echo $row['pdf_data'];

// Close the connection
sqlsrv_close($conn);
?>
