Why is My PHP Code Halting Execution and How Can I Fix the 'unknown table status: TABLE_TYPE' Error?

PHP File Halting Code Execution

In your PHP code, you've mentioned an issue where the program is not entering a specific region of the code, resulting in a halted execution.

Identifying Potential Reasons for Halted Execution:

The error you mentioned, "unknown table status: TABLE_TYPE," suggests a potential problem with your database connectivity or SQL query syntax. To address this, we can utilize a divide-and-conquer approach.

Creating Modular Functions for File Handling and Database Interactions:

To simplify your code and ensure proper error handling, let's create separate functions for file operations and database interactions.

Moving Error Handling Outside the Code:

By abstracting error handling into dedicated classes, we improve code readability and maintainability.

Revised Code with Implemented Techniques:

Here's a revised version of your code that incorporates the proposed changes:

// File handling function
function file_put($number, $data) {
    $path = sprintf("C:/temp/wamp/www/file%d.txt", $number);
    file_put_contents($path, $data);
}

// Database handling class
class MySql {
    // ...
}

// Function to perform the required database interactions
function checkin(MySql $DB, $TechID, $ClientID, $SiteID) {
    // ...
}

// Create a database object
$config = ['server' => 'localhost', 'name' => 'root', 'password' => '', 'db' => 'test'];
$db = new MySql($config);

// Perform the checkin operation
checkin($db, 1, 2, 3, 4);

Benefits of the Revised Code:

• Modular functions for file handling and database interactions improve code readability.
• Abstract error handling enhances maintainability.
• Improved code organization and error handling make debugging easier.
