php Excel/CSVへの読み込みまたはエクスポート(utf 8、gbk符号化変換付)

リンク:CSV mysqlデータベースのインポート
 
phpをexcelにインポート-utf 8とgbkの2つの符号化をサポート
 
phpがexcel乱符号化に導入されたのは、utf 8符号化がxpシステムでutf 8符号化のすべてのトランスコードをサポートしていないため、完璧に解決されたからである.
utf-8符号化事例
 
 

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

 
gbk符号化事例
 
 

<?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   excel-utf-8  "; 
echo $filename; 
?> 

 
サイトにアクセスするとexcelにダウンロードします
セルを区別するなら
table表でウェブページを作ればいいです
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="<table>
			<tr>
				<th>left_1</th>
				<td>right_1</td>
			</tr> 
			<tr>
				<th>left_2</th>
				<td>right_2</td>
			</tr>
		</table>"; 

echo $filename; 
?> 

 
===========================================
 
 
1、簡単エクセルを作る
 
 

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

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

 
2、簡単CSVを作る
 
 

<?php
$action =$_GET['action'];
if ($action=='make'){
	$fp = fopen("demo_csv.csv","a"); //  csv  ，        
	$title = array("First_Name","Last_Name","Contact_Email","Telephone"); //     

	$data_1 = array("42343","423432","4234","4234"); 
	$data_2 = array("4234","Last_Name","Contact_Email","Telephone"); 

	$title = implode(",",$title); //  '       
	$data_1 = implode(",",$data_1); //   '       
	$data_2 = implode(",",$data_2); //   '       

	$data_str =$title."\r
".$data_1."\r
".$data_2."\r
"; //     
	fwrite($fp,$data_str); //     
	fclose($fp); //      
	echo "    ";
}
echo "<br>";
echo "<a href='?action=make'>  csv  </a>";
?>
