Are there specific debugging techniques or functions in PHP that can help pinpoint issues related to empty queries?

When dealing with empty queries in PHP, one common issue is not properly checking for empty or null values before executing the query. To address this, you can use functions like `empty()` or `isset()` to validate the input data before running the query. Additionally, using error handling techniques such as `try-catch` blocks or error reporting functions like `error_reporting()` can help identify and debug any issues related to empty queries.

// Example code snippet to handle empty queries in PHP
$query = ""; // Empty query
if (!empty($query)) {
    // Execute the query if it is not empty
    // Your query execution code here
} else {
    // Handle the case when the query is empty
    echo "Error: Query is empty";
}
