Why Does My PHP Code Skip Execution After a Failed MySQL Query Creating a File?

PHP File Executing Issues

In a PHP file, I encounter a problem where the program skips executing a specific code block despite the successful execution of the preceding and subsequent code. Analysis reveals that the issue arises during an attempt to create a file, specifically file4.txt. This is indicated by the presence of a logic block where the program checks whether the $row2['Type'] is not equal to "Checkin." However, further investigation into the mysql query assigned to the $query variable uncovers a potential reason for the execution failure.

MySQL Query Issue

The query in question is responsible for retrieving data from the Log table where the TechID matches the provided TechID and ordering the results descending based on LogTime. While the expected functionality of the query is to retrieve the latest record for the specified TechID, a strange error persists, indicating "unknown table status: TABLE_TYPE." This error suggests an issue with the MySQL database setup, potentially related to a missing or improperly configured TABLE_TYPE column.

Debugging and Resolution

To resolve this issue, I recommend the following troubleshooting steps:

1. Examine the database structure: Verify the existence and proper configuration of the TABLE_TYPE column in the Log table.
2. Test the query: Execute the query directly using a MySQL client or tool to isolate the issue and identify any syntax errors or database configuration problems.
3. Use try-catch blocks: Surround the query execution with try-catch blocks to handle any exceptions and obtain meaningful error messages.
4. Review the MySQL server logs: Check the MySQL server logs for additional error messages that could provide insights into the problem.
