php导入到excel乱码是因为utf8编码在xp系统不支持所有utf8编码转码一下就完美解决了

访问网站的时候就下载到excel里面
要弄单元格区别的话
用table表格做网页的就可以了
====================== 其他方法 =============================
1、制作简单 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、制作简单 CSV
<?php
$action =$_GET[action];
if ($action==make){
$fp = fopen("demo_csv.csv","a"); //打开csv文件，如果不存在则创建
$title = array("First_Name","Last_Name","Contact_Email","Telephone"); //第一行数据
$data_1 = array("42343","423432","4234","4234");
$data_2 = array("4234","Last_Name","Contact_Email","Telephone");
$title = implode(",",$title); //用 分割成字符串
$data_1 = implode(",",$data_1); // 用 分割成字符串
$data_2 = implode(",",$data_2); // 用 分割成字符串
$data_str =$title."/r/n".$data_1."/r/n".$data_2."/r/n"; //加入换行符
fwrite($fp,$data_str); // 写入数据
fclose($fp); //关闭文件句柄
echo "生成成功";
}
echo "
";
echo "生成csv文件";
?>
也可以做一个封闭函数：
封闭函数一：
function exportToCsv($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($row[ ame],$row[address]));
...
exportToCsv($csv_data, ew_file.csv);
*/
封闭函数二：
<?
/**
* Simple class to properly output CSV data to clients. PHP 5 has a built
* in method to do the same for writing to files (fputcsv()), but many times
* going right to the client is beneficial.
*
* @author Jon Gales
*/
class CSV_Writer {
public $data = array();
public $deliminator;
/**
* Loads data and optionally a deliminator. Data is assumed to be an array
* of associative arrays.
*
* @param array $data
* @param string $deliminator
*/
function __construct($data, $deliminator = ",")
{
if (!is_array($data))
{
throw new Exception(CSV_Writer only accepts data as arrays);
}
$this->data = $data;
$this->deliminator = $deliminator;
}
private function wrap_with_quotes($data)
{
$data = preg_replace(/"(.+)"/, \""$1"", $data);
return sprintf(\"%s", $data);
}
/**
* Echos the escaped CSV file with chosen delimeter
*
* @return void
*/
public function output()
{
foreach ($this->data as $row)
{
$quoted_data = array_map(array(CSV_Writer, wrap_with_quotes), $row);
echo sprintf("%s/n", implode($this->deliminator, $quoted_data));
}
}
/**
* Sets proper Content-Type header and attachment for the CSV outpu
*
* @param string $name
* @return void
*/
public function headers($name)
{
header(Content-Type: application/csv);
header("Content-disposition: attachment; filename={$name}.csv");
}
}
/*
//$data = array(array("one","two","three"), array(4,5,6));
$data[] = array("one","two","three");
$data[] = array(4,5,6);
$csv = new CSV_Writer($data);
$csv->headers( est);
$csv->output();
*/
3. 使用excel类
<?php
require_once Spreadsheet/Writer.php;
$workbook = new Spreadsheet_Excel_Writer();
/* 生成 CSV
$filename = date(YmdHis)..csv;
$workbook->send($filename); // 发送 Excel 文件名供下载
*/
// 生成 Excel
$filename = date(YmdHis)..xls;
$workbook->send($filename); // 发送 Excel 文件名供下载
$workbook->setVersion(8);
$workbook->setBIFF8InputEncoding(UTF-8);
$worksheet =& $workbook->addWorksheet("Sheet-1");
$data[]= array(id,username,company,email,mob,daytime,intent);
$data[] = array(1,老梁,**工作室,\,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]); // 在 sheet-1 中写入数据
}
}
/*
$worksheet =& $workbook->addWorksheet("Sheet-2");
$data[]= array(id,username,company,email,mob,daytime,intent);
$data[] = array(1,老梁,**工作室,\,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]); // 在 sheet-2 中写入数据
}
}
*/
$workbook->close(); // 完成下载
?>
类二 —–函数说明
function Read_Excel_File($ExcelFile,$Result)
$ExcelFile Excel文件名
$Result 返回的结果
函数返回值 正常返回0，否则返回错误信息
返回的值数组
$result[sheet名][行][列] 的值为相应Excel Cell的值
建立Excel文件
function Create_Excel_File($ExcelFile,$Data)
$ExcelFile Excel文件名
$Data Excel表格数据
请把函数写在PHP脚本的开头
例1：
<?
require "excel_class.php";
Read_Excel_File("Book1.xls",$return);
for ($i=0;$i<count($return[Sheet1]);$i++)
{
for ($j=0;$j<count($return[Sheet1][$i]);$j++)
{
echo $return[Sheet1][$i][$j]."|";
}
echo "
";
}
?>
例2：
<?
require "excel_class.php";
Read_Excel_File("Book1.xls",$return);
Create_Excel_File("ddd.xls",$return[Sheet1]);
?>
