PHP Functions to Import/Export CSV data

CSVEport()

This function has just one argument – the query that returns the necessary data to be exported.
Example: CSVExport("SELECT name,username,email,url FROM User WHERE status=1");

CSVImport()

This will upload a CSV file and import the data into the specified table. This function must have the following arguments…

$table
The name of the table the data must be imported to
$fields
An array of fields that will be used
$csv_fieldname
The name of the CSV file field

Example: CSVImport("User", array('name','username','email','url'), "csv_file");

Code
