Displaying Results from a Stored Procedure in SQL Server using PHP

When working with databases, retrieving data efficiently is a critical skill for developers. One common scenario involves executing a stored procedure in SQL Server and fetching its results using PHP. In this guide, we will explore a common issue and its solution: how to display output from a stored procedure created in SQL Server through a PHP script.

Understanding the Problem

Imagine you have a stored procedure named sp_cigar_account_search that takes several parameters and returns a result set when invoked correctly. However, you find yourself unable to display the fetched results in PHP despite the procedure executing successfully. Instead of data, you're greeted with a generic success message.

Here’s an example of how you might be implementing it:

In this code, while you successfully execute the procedure, you don’t fetch any data to display.

How to Fetch and Display Results

To get the data returned by your stored procedure, you need to use either sqlsrv_fetch_array() or sqlsrv_fetch_object(). Below is the revised function with these changes integrated.

Adjusted Function

Here is the updated version of the account_search_sp function that will properly fetch and handle the returned data:

Key Components Explained

Preparing the Statement: sqlsrv_prepare($db, $sql, $procedure_params) prepares your stored procedure call to be executed with the provided parameters.

Execution: Checking if the statement was executed successfully is vital. On failure, it outputs details using sqlsrv_errors(), enabling debugging.

Fetching Data: The while loop utilizes sqlsrv_fetch_array($stmt) to iterate over the results and store them in an array $data which you can return and manipulate as needed.

Output: You can enhance this further by formatting the output of the $data array into a readable table or other formats depending on your requirement.

Conclusion

By making these simple adjustments to your function, you can successfully pull results from your SQL Server stored procedure and display them using PHP. This approach not only empowers you to manage data effectively, but also prepares you to troubleshoot any potential errors. Happy coding!
