What potential pitfalls should be considered when working with BLOB data types in Oracle databases using PHP?

When working with BLOB data types in Oracle databases using PHP, potential pitfalls to consider include memory usage, performance issues, and data integrity. To avoid these pitfalls, it's important to properly handle BLOB data by using bind variables, limiting the amount of data fetched at once, and optimizing queries to minimize resource consumption. 

// Example code snippet to fetch BLOB data from Oracle database using bind variables

$blobId = 1;

$sql = "SELECT blob_column FROM table_name WHERE id = :id";
$stmt = oci_parse($conn, $sql);
oci_bind_by_name($stmt, ":id", $blobId);
oci_execute($stmt);

$row = oci_fetch_assoc($stmt);
$blobData = $row['BLOB_COLUMN'];

oci_free_statement($stmt);
