of with utf8 gbk encoding conversion based on php export to Excel or CSV

php imported into excel because the utf8 encoding in xp system does not support all utf8 encoding transcoding 1 solved perfectly
The utf-8 coding case
Php code

<?php 
header("Content-Type: application/vnd.ms-excel; charset=UTF-8"); 
header("Pragma: public"); 
header("Expires: 0"); 
header("Cache-Control: must-revalidate, post-check=0, pre-check=0"); 
header("Content-Type: application/force-download"); 
header("Content-Type: application/octet-stream"); 
header("Content-Type: application/download"); 
header("Content-Disposition: attachment;filename=11.xls "); 
header("Content-Transfer-Encoding: binary "); 
?>  

Php code

<?    
$filename="php Imported into the excel-utf-8 coding ";    
$filename=iconv("utf-8", "gb2312", $filename);    
echo $filename;    
?>   

The gbk coding case
Php code

<?php 
header("Content-Type: application/vnd.ms-excel; charset=UTF-8"); 
header("Pragma: public"); 
header("Expires: 0"); 
header("Cache-Control: must-revalidate, post-check=0, pre-check=0"); 
header("Content-Type: application/force-download"); 
header("Content-Type: application/octet-stream"); 
header("Content-Type: application/download"); 
header("Content-Disposition: attachment;filename=11.xls "); 
header("Content-Transfer-Encoding: binary "); 
?>  

Php code

0.<?    
0.$filename="php Imported into the excel-utf-8 coding ";    
0.echo $filename;    
0.?>   

Download to excel when you visit the website
If you want to differentiate the cells
Use the table form for web pages

1. Simple Excel

0.<?php   
0.header("Content-type:application/vnd.ms-excel");   
0.header("Content-Disposition:filename=php2excel.xls");   
0.  
0.echo "A1/t B1/t C1/n";   
0.echo "A2/t B2/t C2/n";   
0.echo "A3/t B3/t C3/n";   
0.echo "A4/t B4/t C4/n";   
0.?>  

2. Simple CSV

<?php
$action =$_GET['action'];
if ($action=='make'){
 $fp = fopen("demo_csv.csv","a"); // Open the csv The file is created if it does not exist 
 $title = array("First_Name","Last_Name","Contact_Email","Telephone"); // The first 1 Rows of data 
 $data_1 = array("42343","423432","4234","4234"); 
 $data_2 = array("4234","Last_Name","Contact_Email","Telephone"); 
 $title = implode(",",$title); // with  '  Split into strings 
 $data_1 = implode(",",$data_1); //  with  '  Split into strings 
 $data_2 = implode(",",$data_2); //  with  '  Split into strings 
 $data_str =$title."/r/n".$data_1."/r/n".$data_2."/r/n"; // Add a newline character 
 fwrite($fp,$data_str); //  Write data 
 fclose($fp); // Close the file handle 
 echo " Generate success ";
}
echo "<br>";
echo "<a href='?action=make'> generate csv file </a>";
?>

A closed function can also be made:
Closed function 1:

function exportToCsv($csv_data, $filename = 'export.csv') {
    $csv_terminated = "/n";
    $csv_separator = ",";
    $csv_enclosed = '"';
    $csv_escaped = "//";
    // Gets the data from the database
    $schema_insert = '';
    $out = '';
    // Format the data
    foreach ($csv_data as $row)
    {
        $schema_insert = '';
        $fields_cnt = count($row);
        //printr($row);
        $tmp_str = '';
        foreach($row as $v)
        {
            $tmp_str .= $csv_enclosed.str_replace($csv_enclosed, $csv_escaped . $csv_enclosed, $v).$csv_enclosed.$csv_separator;
        } // end for

        $tmp_str = substr($tmp_str, 0, -1);
        $schema_insert .= $tmp_str;
        $out .= $schema_insert;
        $out .= $csv_terminated;
    } // end while
    header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
    header("Content-Length: " . strlen($out));
    header("Content-type: text/x-csv");
    header("Content-Disposition:filename=$filename");
    echo $out;
}
/*
$csv_data = array(array('Name', 'Address'));
array_push($csv_data, array($row['name'],$row['address']));
...
exportToCsv($csv_data,'new_file.csv');
*/

Closed function 2:

3. Use the excel class

<?php

$workbook = new Spreadsheet_Excel_Writer();
/*  generate  CSV
$filename = date('YmdHis').'.csv';
$workbook->send($filename); //  send  Excel  File name for download 
*/
//  generate  Excel
$filename = date('YmdHis').'.xls';
$workbook->send($filename); //  send  Excel  File name for download 
$workbook->setVersion(8);
$workbook->setBIFF8InputEncoding('UTF-8');
$worksheet =& $workbook->addWorksheet("Sheet-1");
$data[]= array('id','username','company','email','mob','daytime','intent');
$data[] = array(1,' The old beam ','** The studio ','ofstack.com','1363137966*',time(),'y');
$total_row = count($data);
$total_col = count($data[0]);
for ($row = 0; $row < $total_row; $row ++) {
   for ($col = 0; $col < $total_col; $col ++) {
  $worksheet->writeString($row, $col, $data[$row][$col]); //  in  sheet-1  Write data in 
   }
}
/*
$worksheet =& $workbook->addWorksheet("Sheet-2");
$data[]= array('id','username','company','email','mob','daytime','intent');
$data[] = array(1,' The old beam ','** The studio ','ofstack.com','1363137966*',time(),'y');
$total_row = count($data);
$total_col = count($data[0]);
for ($row = 0; $row < $total_row; $row ++) {
   for ($col = 0; $col < $total_col; $col ++) {
  $worksheet->writeString($row, $col, $data[$row][$col]); //  in  sheet-2  Write data in 
   }
}
*/
$workbook->close(); //  The download is complete 
?>

Class 2
-- Function description
Read the Excel file
function Read_Excel_File($ExcelFile,$Result)
$ExcelFile Excel file name
$Result returns the result
The function returns 0 normally, otherwise an error message is returned
Returns an array of values
The value of $result[sheet name][row][column] is the corresponding value of Excel Cell

Create the Excel file
function Create_Excel_File($ExcelFile,$Data)
$ExcelFile Excel file name
$Data Excel table data
Write the function at the beginning of the PHP script
Case 1:

<?
require "excel_class.php";
Read_Excel_File("Book1.xls",$return);
for ($i=0;$i<count($return[Sheet1]);$i++)
{
    for ($j=0;$j<count($return[Sheet1][$i]);$j++)
    {
        echo $return[Sheet1][$i][$j]."|";
    }
    echo "<br>";
}
?>

Example 2:

<?    
$filename="php Imported into the excel-utf-8 coding ";    
$filename=iconv("utf-8", "gb2312", $filename);    
echo $filename;    
?>
