我需要使用 PHP将CSV文件中的所有字符串和数字双引号括起来.

如何在双引号内的所有数据中从PHP创建CSV文件？

我正在使用此代码生成CSV – 我正在使用codeignITer框架

$array = array(
    array(
     (string)'XXX XX XX',(string)'3',(string)'68878353',(string)'',(string)'xxxx@xxxx.xxx.xx',),);

$this->load->helPEr('csv');
array_to_csv($array,'blueform.csv');

输出我得到：

"XXX XX XX",3,68878353,xxxx@xxxx.xxx.xx

预期产量：

"XXX XX XX","3","68878353","","xxxx@xxxx.xxx.xx"

array_to_csv的代码

if (!function_exists('array_to_csv')) {
    function array_to_csv($array,$download = "") {
        if ($download != "") {   
            header('Content-type: application/csv');
            header('Content-Disposition: attachement; filename="' . $download . '"');
        }

        ob_start();
        $f = fopen('PHP://output','w') or show_error("Can't open PHP://output");
        $n = 0;
        foreach ($array as $line) {
            $n++;
            if (!fputcsv($f,$line)) {
                show_error("Can't write line $n: $line");
            }
        }
        fclose($f) or show_error("Can't close PHP://output");
        $str = ob_get_contents();
        ob_end_clean();

        if ($download == "") {
            return $str;
        } else {
            echo $str;
        }
    }
}

先谢谢你

int fputcsv ( resource $handle,array $fields [,string $delimiter = "," [,string $enclosure = '"' [,string $escape_char = "\" ]]] )
