Question

我的PHP代码中有一个包含大约200个列元素的数组。它看起来像这样：

就像我说的那样，这种情况持续到大约199/200。我今天发现CSV将保持这个顺序，但他们在随机顺序中添加了大约30个字段。一些将在前20个，一些在110和120之间。是否有更好的做法在这里添加新元素？我已经将它们添加到了他们需要的数据库中，但现在我需要将它们放在数组中的正确位置，我不知道是否有一种方法可以不重新编号整个数组。

更新完整代码，除了编码长或重复元素的地方

last parameter

使用包含列名的第一行导入CSV文件。

允许您定义CSV中列名称与要导入数据的表格中的列名称之间的转换。

<?php

//  $c_colslist is an array of name/value pairs. The name matches a name in the CSV, 
//  while the value is the name of the column in the table where the value is stored.
//  If there are changes in the CSV, you only have to edit this array and the table staging.
//  If the change is only a change in the order of the fields, you do not have to edit anything.
$c_colslist = array(
    'orderNumber' => 'orderNumber',
    'place' => 'place',
    'workOrderNum' => 'workOrderNum',
    'Column1' => 'userName'
);


//  $csvCols is an array containing the list of column names found in the CSV file, in the order they are found.
$csvCols = array();

//  

$file = $_FILES["file"]["tmp_name"];
$handle = fopen($file, "r");


//  $rowIDs will contain a list of the unique IDs of all inserted rows.
$rowIDs = array();

$rowno = 0;
while(!feof($handle)){
    //  Get the row of data.
    //  If 1st row, it has the column names
    $rowno++;
    $row = fgetcsv($handle, 0, ",");
    if($rowno == 1) {
        //  Save the column name list
        $csvCols = $row;
        //  Pre-create the insert statement (all but the data)
        $qstr = "";
        $qstr .= "INSERT INTO `staging` (";
        $cols = array();
        //  $col_idx contains a list of indexes for each CSV column name (ie. the order they are found in the file)
        $col_idx = array(0);
        $colno = 0;
        foreach($csvCols as $idx => $c_colname) {
            $cols[$colno] = "`".$c_colslist[$c_colname]."`"
            $col_idx[$c_colname] = $colno;
            $colno++;
        }
        $qstr .= implode(',',$cols). ") ";
    } else {
        //  Build the INSERT statement
        $mqstr = $qstr; //  Start with the query string created when the first row was read.
        $mqstr .= ") VALUES (";
        //  Get the values in the same order as the columns.
        $vals = array();
        foreach($csvCols as $idx => $c_colname) {
            $val[] = "'".$row[$col_idx[$c_colname]]."'";
        }
        $mqstr .= implode(',',$vals);
        $mqstr .= ");";
        $query = mysqli_query($connect, $mqstr);
        $rowIDs[] = mysqli_insert_id($connect);
    }

}

//  Now we can copy the records into the other tables.
