Answer & Solution
Correct Answer:
Option
D
This question is asking about how MySQL's `mysql_query()` function behaves when a query fails.
`mysql_query()` is a function used to execute SQL queries in MySQL. It returns a value that tells you whether the query was successful or not.
Here's how it works:
* If the query is successful, `mysql_query()` returns a non-zero value (usually a resource ID). * If the query fails, `mysql_query()` returns `FALSE` (which is equivalent to `0`).
Therefore, the correct answer is Option A: 0.
Important Note:
The `mysql_query()` function is considered deprecated in newer versions of PHP. It's recommended to use the MySQLi or PDO extensions for interacting with MySQL databases instead.
