Alter Tabled using PHP Query, Column Name doesn

Question

This is my first post, and there is a similar post here: phpMyAdmin doesn't show added columns - Stack Overflow

But since no one has answered, I will ask here and provide more details in hoping to resolve this issue. I have a table in my database that I needed to be able to add additional columns to. I've done this using the following query:

$sql = "ALTER TABLE tablename ADD columnname INT(11)";  //Run the query....

This worked perfect on day one, however on day two when I tried to add an additional column via this php script, it appears to work from the phpMyAdmin Structure view. The column is in there with the correct columnname and datatype. However when I switch to the Browse view, there is no Column Name, just blank columns filled with "null" values. But, if you click on an individual row, it shows the correct column name, and a value (if one exists for that row).

I've tried running Analyze Table, as I read somewhere that that would update the Schema. However, I haven't had any success with that fixing it. I'd prefer to not have to delete the table and restart, especially if I run into this issue again. As this is my first post, I've tried to format everything correctly, but please forgive me if I didn't. Also, I can grab screenshots if anyone is having issues understanding my question.

Answer 1

if you can, restart mysql, it should flush everything, including mysql caches phpmyadmin may be using.
