What potential pitfalls should be considered when querying an Interbase database in PHP?

When querying an Interbase database in PHP, potential pitfalls to consider include SQL injection vulnerabilities, data type mismatches, and error handling. To mitigate these risks, always use prepared statements to prevent SQL injection attacks, ensure that data types match between PHP and the database, and implement proper error handling to catch any issues that may arise during the query execution. 

// Example of querying an Interbase database in PHP with prepared statements and error handling

// Establish a connection to the Interbase database
$db = ibase_connect($host, $username, $password);

// Prepare a SQL statement with placeholders for parameters
$stmt = ibase_prepare($db, "SELECT * FROM table WHERE column = ?");

// Bind the parameter values to the placeholders
$param = 'value';
ibase_execute($stmt, $param);

// Check for errors during query execution
if (($error = ibase_errmsg()) !== false) {
    // Handle the error appropriately, such as logging it or displaying a message to the user
}

// Process the query results
while ($row = ibase_fetch_assoc($stmt)) {
    // Do something with the data
}

// Close the database connection
ibase_close($db);
