Question

我想将CSV数据解析成2d数组。在我的csv文件中，标题如下，按特定值作为列。

CaseNumber IncidentDate IncidentTime位置事件处置 10120323 3/21/2009 .... ........ ...... ...... .....

我设法将所有CSV文件数据复制到一个名为array的数组中在myarray中，我创建了一个只有两个标题的二维数组 array [0] =（

[0] =＆GT; 'IncidentData'，

[1] =＆GT; '配置'）

所以我的最终myarray应该是在CSV数组中的头部和myarray中的头部匹配后得到'IncidentData'和'Disposition'的所有列值

有什么想法吗？

这是我到目前为止所拥有的。

             $nn = 0;
             while (($data = fgetcsv($handle, 0, ",")) !== FALSE) {
                 //# Count the total keys in the row.
                 $c = count($data);
