I have a php script that opens an excel spreadsheet, and imports the data into a mysql table.
For the most part it is working, but it is buggy and unreliable.
It is supposed to update records that exist based on matching phone numbers, and insert when that fails.
For some reason it randomly creates duplicate entries when it should be able to because of the update then insert on fail process.
Can I get some help?
I need help with an Excel to mysql import process.
