This is a <td> in PHP associated with a foreach loop.
1 is the query to select userid from the table
2 is condition to check result exist or not
3 is echo the username after finding it
Now this code exist a potential issue, that is set a initializing variable for $cobrokeusername.
Since it is a loop, system will auto retrieve the before value if the current value is empty.
Below are the example array data:
As you can see, sales8 is not associated with a user ID, so it should not echo anything. However, since the initializing variable for $cobrokeusername hasn't been set, the system will still echo the value from the previous iteration, which is the username associated with the user ID 1001.
So, the output data will be:
Action to avoid this; adding initializing variable to it
After setting the initializing variable, each loop iteration will run with this value, which is an empty value for $cobrokeusername.
Now, the system will be able to get the correct data inside the loop.
Summary:
When you want to output different values inside the loop, it is important to add the initializing variable to the value to avoid the issue of retaining previous values.
