How can the use of addslashes() function impact the security of binary data uploads in PHP?

Using the addslashes() function on binary data uploads in PHP can potentially corrupt the data by adding escape characters, leading to data loss or incorrect interpretation of the binary data. To ensure the security and integrity of binary data uploads, it is recommended to use prepared statements with parameterized queries when interacting with databases, instead of addslashes(). 

// Example of using prepared statements with parameterized queries to handle binary data uploads securely
$stmt = $pdo->prepare("INSERT INTO table_name (binary_data_column) VALUES (:binaryData)");
$stmt->bindParam(':binaryData', $binaryData, PDO::PARAM_LOB);
$stmt->execute();
