$sales = array( array('Northeast','2004-01-01','2004-02-01',12.54),array('Northwest',546.33),array('Southeast',93.26),array('Southwest',945.21),array('All Regions','---','--',1597.34),);

2. 读取csv数据,使用特殊的流输出
<?PHP
/**
* PHP 读写 CSV相关操作
* @param
* @arrange (512.笔记) jb51.cc
**/
$sales = array( array('Northeast',);
$fh = fopen('PHP://output','w');
foreach($sales as $sales_line){
if(fputcsv($fh,$sales_line) === false){
die("Can't write CSV line");
}
}
fclose($fh);

3. 读取csv数据,输出到缓冲中
<?PHP
/**
* PHP 读写 CSV相关操作
* @param
* @arrange (512.笔记) jb51.cc
**/
$sales = array( array('Northeast',);
ob_start();
$fh = fopen('PHP://output','w') or die("Can't open PHP://output");
foreach($sales as $sales_line){
if(fputcsv($fh,$sales_line) === false){
die("Can't write CSV line");
}
}
fclose($fh) or die("Can't close PHP://output");
$output = ob_get_contents(); ob_end_clean();

4. 读取csv文件的数据
<?PHP
/**
* PHP 读写 CSV相关操作
* @param
* @arrange (512.笔记) jb51.cc
**/
$fp = fopen('sample3.csv','r') or die("can't open file");
print "<table>\n";
while($csv_line = fgetcsv($fp)){
print '<tr>';
for($i=0,$j=count($csv_line);
$i<$j; $i++){
// print '<td>'.htmlentities($csv_line[$i]).'</td>';
print '<td>'.htmlentities(iconv("gb2312","utf-8",$csv_line[$i])).'</td>';
}
print "</tr>\n";
}
print "</table>\n";
fclose($fp) or die("can't close file");

5. 下载的CSV文件
<?PHP
/**
* PHP 读写 CSV相关操作
* @param
* @arrange (512.笔记) jb51.cc
**/
$sales = array(array('Northeast',array('中国','w') or die("can't open PHP://output");
$total = 0;
// 告诉浏览器发送的是一个csv文件
header('Content-Type: application/csv');
header('Content-Disposition: attachment; filename="sales.csv"');
// 输出表头
fputcsv($output,array('Region','Start Date','End Date','Amount')); // 输出每一行数据,并递增$total
foreach($sales as $sales_line){
if(fputcsv($fh,$sales_line) === false){
die("Can't write CSV line");
}else{
$total += $sales_line[3];
}
}
fputcsv($fh,$total));
fclose($fh) or die("Can't close PHP://output");
