# csv_iterator
 
#### 介绍
csv文件迭代器，可以遍历读取文件

#### 安装教程
```bash
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
    ```
1. 编写如下PHP代码
    ```php
    <?php
 
    $it = new \DreamCat\CsvIterator\CsvIterator("test.csv");
    foreach ($it as $key => $item) {
        echo json_encode([$key, $item]);
    }
    ```
1. 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"}]
    ```
1. 会自动跳过空行，如果文件不存在或打不开，会抛出异常
