将字符串格式化为csv数据

fputcsv() 函数用于将数据格式为csv格式，以便写入文件或者数据库。

1.将字符串写入csv文件中

    $test_array = array(
        array("111","sdfsd","sdds","43344","rrrr"),
        array("sssssssss","gdfgfd","232323","wwewe","dsfds"),
        array("fgfg","e4343","dsfds","w2332","xcvxc"),
        array("11212","2323","344343","344343","rerreer"),
        array("fds","43344444","33333333","ttttttt","gggggggggggg"),
        array("kdfs","dsfdsfds","wewewe","sdsdddddddd","wwwwwwwwwww")
    );
    
    $file = fopen("test.csv","w") or die("Can't Open test.csv");
    foreach($test_array as $line_array)
    {
        $isSuccess = fputcsv($file,$line_array);
        print $isSuccess."<br>";
　　　　　if($isSuccess===false)
        {
            die("Can't write csv line".$line_array);
        }
    }
    fclose($file) or die("Can't close file test.csv.");

fputcsv()函数返回所写入行的字符的个数或者false，当写入失败时返回false。

2.将格式化的csv字符串保存到字符串中。

$test_array = array(
        array("111","sdfsd","sdds","43344","rrrr"),
        array("sssssssss","gdfgfd","232323","wwewe","dsfds"),
        array("fgfg","e4343","dsfds","w2332","xcvxc"),
        array("11212","2323","344343","344343","rerreer"),
        array("fds","43344444","33333333","ttttttt","gggggggggggg"),
        array("kdfs","dsfdsfds","wewewe","sdsdddddddd","wwwwwwwwwww")
    );
    ob_start();
    $file = fopen("php://output","w") or die("Can't Open php://output");
    foreach($test_array as $line_array)
    {
        $isSuccess = fputcsv($file,$line_array);
        if($isSuccess===false)
        {
            die("Can't write csv line".$line_array);
        }
    }
    
    fclose($file) or die("Can't close file test.csv.");
    $result = ob_get_contents();
    ob_end_clean();
