Instructions are as follows:
1. Generate csv file
Copy the code The code is as follows:

$arr_export_titles = array("student number","student number"," Student name");
$csvfile = new csvDataFile("", ",", "w");
echo $csvfile->printline($arr_export_titles);
//Method 1
$print_data1[] = 1;
$print_data1[] = "039413301";
$print_data1[] = "Zhang San";
echo $csvfile->printline($print_data1);
$print_data2[] = 2;
$print_data2[] = "039413302 ";
$print_data2[] = "李思";
echo $csvfile->printline($print_data2);
$print_data3[] = 3;
$print_data3[] = "039413303";
$print_data3[] = "王五";
echo $csvfile->printline($print_data3);
//Method 2
$print_data[1][] = 1;
$print_data[1][] = "039413301";
$print_data [1][] = "Zhang San";
$print_data[2][] = 2;
$print_data[2][] = "039413302";
$print_data[2][] = "李思";
$print_data[3][] = 3;
$print_data[3][] = "039413303";
$print_data[3][] = "王五";
echo $csvfile->printcsv($print_data);
Copy code The code is as follows:
require "./include/csvdatafile.php";
$filename = "E:/development/csvfile/datefile. csv";
// Read file source
$handle = fopen($filename, "r");
$contents = fread($handle, filesize($filename));
fclose($handle);
// format content for special chars
$contents = @addslashes($contents);
$contents = @str_replace(',', ' ,', $contents);
$contents = @stripslashes($contents);
// Write to new file
$handle = @fopen($filename, "w");
@fwrite($handle, $contents);
@fclose($handle);
$fd = @fopen($filename, "rb") ;
$first_line = str_replace(' ,',',',str_replace('"','',trim(@fgets($fd, 1000)))) ;
@fclose($fd);
if($ first_line != "Student number, student number, student name") {
$pass = false;
}
if($pass){
$csv = new csvDataFile($filename);
while($csv->next_Row ()) {
$userid = trim($csv->f('Student ID'));
$classno = trim($csv->f('Student ID'));
$username = trim( $csv->f('Student Name'));
