解析CSV时的行为异常

如何解决解析CSV时的行为异常

| 解析CSV（带有2个栏目）时遇到了问题 数组（[0] =>数组（[0] => oldcustomer 1 => newcostumer 4245945 [2] => 6773197 4260367 [3] => 6773381 4889300 [4] => 6764472 4740434 [5] => 6764555 4710449 [6 ] => 6764560 我希望它在单独的数组中，并且newcostumerID与\“ oldcustomer ID \”混合在一起 CSV档案： 老顾客;新顾客 4245945; 6773197 4260367; 6773381 4889300; 6764472 4740434; 6764555 4710449; 6764560 4699714; 6766531 4451642; 6775682 4534699; 6775683 4378586; 6775684 4711005; 6775685 4502714; 6775686 4288738; 6775687 CSV解析（从这里被盗）

解决方法

        查看爆炸功能。拿起您的字符串并运行explode（\“ \\ n \”，$ string）以获取一个行数组。然后遍历每行并在上爆炸;字符。

$rows = explode(\"\\n\",$string);
$oldcustomer = array();
$newcustomer = array();
foreach ($rows as $row) {
  $columns = explode(\";\",$row);
  $oldcustomer[] = $columns[0];
  $newcustomer[] = $columns[1];
}
print_r($oldcustomer);
print_r($newcustomer);

    ,        您可以使用以下代码解决您的问题

$row = -1;
$oldcustomer=array();
$newcustomer=array();
if (($handle = fopen(\"yourfile.csv\",\"r\")) !== FALSE) {
    while (($data = fgetcsv($handle,1000,\";\")) !== FALSE) {
        if($row==-1){//Skipping first line
            $row++;
            continue;
        }
        $oldcustomer[$row]=$data[0];
        $newcustomer[$row]=$data[1];
        $row++;
    }
    fclose($handle);
    print_r($oldcustomer);
    print_r($newcustomer);
}
