Problems with the Select dropdown box in PHP
This is a modify page drop-down box Please select Finance Department Office Product Development Dept. Application Development Department
I want to open the Modify page every time the default is the value read from the database $project_department, but now each time is displayed "please select"
Ask the gods how to write? I wrote one down here, but it didn't work.
