php将数组(数据库中的数据)写入保存为csv文件

php将数组解析保存为csv文件，源代码如下：

<?php
/* http://www.manongjc.com/article/1307.html */
$sales = array( array('Northeast',12.54),
                array('All Regions',1597.34) );

$fh = fopen('sales.csv','w') or die("Can't open sales.csv");
foreach ($sales as $sales_line) {
    if (fputcsv($fh, $sales_line) === false) {
        die("Can't write CSV line");
    }
}
fclose($fh) or die("Can't close sales.csv");

?>
