php 读取或导出到Excel / CSV （附utf8、gbk 编码转换）

链接：CSV 导入mysql 数据库

 

php导入到excel-支持utf8和gbk两种编码

 

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

utf-8编码案例

 

 

<?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 "); 
?>  

 

<? 
$filename="php导入到excel-utf-8编码"; 
$filename=iconv("utf-8", "gb2312", $filename); 
echo $filename; 
?> 

 

gbk编码案例

 

 

<?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 "); 
?>  

 

<? 
$filename="php导入到excel-utf-8编码"; 
echo $filename; 
?> 

 

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

例如：

 

 

<?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 "); 

$filename="<table>
			<tr>
				<th>left_1</th>
				<td>right_1</td>
			</tr> 
			<tr>
				<th>left_2</th>
				<td>right_2</td>
			</tr>
		</table>"; 

echo $filename; 
?> 

 

====================== 其他方法 =============================

 

 

1、制作简单 Excel

 

 

<?php
header("Content-type:application/vnd.ms-excel");
header("Content-Disposition:filename=php2excel.xls");

echo "A1\t B1\t C1\n";
echo "A2\t B2\t C2\n";
echo "A3\t B3\t C3\n";
echo "A4\t B4\t C4\n";
?>

 

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 "<br>";
echo "<a href='?action=make'>生成csv文件</a>";
?>

 

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($row['name'],$row['address']));
...

exportToCsv($csv_data,'new_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('test');
$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','[e-mail]','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','[e-mail]','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
读取Excel文件
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 "<br>";
}
?>

 

例2：

 

<?
require "excel_class.php";

Read_Excel_File("Book1.xls",$return);
Create_Excel_File("ddd.xls",$return[Sheet1]);
?>
