How can the problem of an "invalid identifier" error when using oci_parse in PHP be addressed?

When encountering an "invalid identifier" error with oci_parse in PHP, it typically means that the SQL query being passed to oci_parse contains a reference to a table or column that does not exist in the database schema. To address this issue, carefully review the SQL query and ensure that all table and column names are spelled correctly and exist in the database. 

// Example code snippet to address an "invalid identifier" error with oci_parse
$connection = oci_connect("username", "password", "localhost/XE");

$query = "SELECT * FROM users_table"; // Incorrect table name causing the error

$statement = oci_parse($connection, $query);

if (!$statement) {
    $error = oci_error($connection);
    echo "Error parsing query: " . $error['message'];
} else {
    // Execute the statement and fetch results
    oci_execute($statement);
    // Further processing of fetched data
}

oci_close($connection);
