What are some best practices for handling blob data in PHP when querying a database like Interbase?

When handling blob data in PHP when querying a database like Interbase, it is important to properly handle the retrieval and storage of binary data. One best practice is to use prepared statements to safely retrieve and insert blob data into the database. Additionally, it is recommended to use appropriate encoding/decoding functions to handle the binary data correctly. 

// Example of retrieving blob data from Interbase database using prepared statements

$blobId = 1;

// Connect to Interbase database
$database = ibase_connect('localhost:employee.fdb', 'username', 'password');

// Prepare and execute query to retrieve blob data
$query = "SELECT blob_field FROM table_name WHERE id = ?";
$stmt = ibase_prepare($database, $query);
ibase_execute($stmt, $blobId);

// Fetch the blob data
$row = ibase_fetch_assoc($stmt);
$blobData = ibase_blob_get($row['BLOB_FIELD']);

// Close database connection
ibase_close($database);

// Output the blob data
echo $blobData;
