What does the error message 'Resource id #8' indicate in PHP when using the db2_exec function?

The error message 'Resource id #8' in PHP when using the db2_exec function indicates that the function has returned a resource identifier instead of the expected result set. This typically occurs when there is an issue with the SQL query being executed, such as a syntax error or invalid query. To solve this issue, you should check the SQL query for any errors and make sure it is properly formatted. 

// Assuming $conn is the DB2 connection resource
$sql = "SELECT * FROM table_name";
$stmt = db2_exec($conn, $sql);

if($stmt === false) {
    echo "Error executing query: " . db2_stmt_errormsg();
} else {
    // Process the result set
}
