Question

我在将 CSV 字符串解析为多维数组时遇到问题。我已经看过这个问题 PHP CSV string to array 但我没有得到相同的结果..

打印在屏幕上的 CSV 如下所示：

这看起来很像一个班轮。但是，当我将此数据导出到文件并使用 Excel 打开时，数据格式很好。

它在 Excel 中的样子

然而，在我可以将它发送到一个文件之前，我需要对其进行操作，为此我想将它更改为一个数组。但是什么时候做：

$test = explode(",", $csvString);
echo '<pre>'; print_r($test); echo '</pre>';

我得到的并不是我想要的。我想得到多维数组，但我得到的是一个单一的数组，它只是介于两者之间的名称。

输出旧方法：

    [33] => 10
    [34] => 6
    [35] => 62.5%
    [36] => 37.5%

输出第二种方法：

    // Curls stuff above, to access the file 
    // Curl accesses the correct path to the url and save is in a variable.
    // Session at this point is still open 

    $csvData = file_get_contents($url);
    $lines = explode(PHP_EOL, $csvData);
    $array = array();
    foreach ($lines as $line) {
        $array[] = str_getcsv($line);
    }
    var_dump($array);

    echo '<pre>'; print_r($array); echo '</pre>';

使用上述方法输出

    var_dump
    array(1) { [0]=> array(1) { [0]=> string(3) "ï»¿" } }

    echo
    Array
    (
        [0] => Array
            (
                [0] => ï»¿
            )
     )

编辑 最后，在四处移动代码并仔细检查所有内容后，我发现我没有指向一个变量，而是指向一个方法...

Answer 1

您没有按照您引用的示例中显示的内容进行操作。在那个例子中，文件被读取，首先在 EOL 上展开以获得单独的行，然后每一行在'，'上单独展开以获得多维数组......该代码有什么问题？

仅仅通过“,”来解析 CSV 文件中的字段是完全错误的。这里面有很多细微差别。例如逗号可以嵌入字段中。
