介绍

csv文件迭代器，可以遍历读取文件

安装教程

composer require dreamcat/csv_iterator

使用说明

1. 首先确保存在 csv 文件，test.csv，文件内容如下

    header1,header2,header3,header4
    data11,data12,data13,data14
    data21,data22,,
    data31
    data41,data42,data43,data44,data45
   

2. 编写如下PHP代码

    <?php
    
    $it = new \DreamCat\CsvIterator\CsvIterator("test.csv");
    foreach ($it as $key => $item) {
        echo json_encode([$key, $item]);
    }
   

3. 输出如下：

    [0,{"header1":"data11","header2":"data12","header3":"data13","header4":"data14"}]
    [1,{"header1":"data21","header2":"data22","header3":"","header4":""}]
    [2,{"header1":"data31","header2":null,"header3":null,"header4":null}]
    [3,{"header1":"data41","header2":"data42","header3":"data43","header4":"data44","4":"data45"}]
   

4. 会自动跳过空行，如果文件不存在或打不开，会抛出异常
