A small example of php reading (opening) csv files

//Set UTF-8 encoding
setlocale(LC_ALL, 'en_US.UTF-8');
//csv path
$csv_file = "csv/excel. csv";
//Open the file in read-only mode
$handle = fopen($csv_file, "r");
//Define the result array
$listarr = array();
//Open a line in csv and use " ,"Split into arrays
while($data = fgetcsv($handle, 1000, ",")){
 $num = count($data);
 for($i=0; $i<$num; $i++ ){
 $data[$i] = mb_convert_encoding($data[$i],"UTF-8","UTF-8");
 }// bbs.it-home.org
 $listarr[] = $ data;
}
return $listarr;
