通读文件，并添加号码组的部分 [英] Read through a file, and add numbers to array parts

问题描述

我有一个CSV数以千计相互下面的数字文件。让我们通过使用此简化：

I have a CSV file with thousands of numbers underneath each other. Let's simplify by using this:

4
7
1
9
3
3
8
6
2

我要的是输出与每个键3个数字（用逗号崩盘）数组：

What I want is to output an array with 3 numbers per key (imploded by a comma):

array (
  [0] => 4,7,1
  [1] => 9,3,3
  [2] => 8,6,2
)

我已经成功地得到这个，读取CSV：

I've managed to get to this, reading the CSV:

$path = "data.csv";
$row = 1;
if (($handle = fopen($path, "r")) !== FALSE) {
  while (($data = fgetcsv($handle, 1000, "\r\n")) !== FALSE) {
    $cell = 0;
    $table[$row][$cell] = $data[0];
    $cell++;
  }
  fclose($handle);
}

我只是困惑，凡我怎么有最多$行和$细胞得到我想要的输出。你能帮忙吗？

I am just confused as to where an how I have to up $row and $cell to get the output I want. Could you help?

推荐答案

使用此，我测试和工程：

Use this, I tested and works:

<?php
$path = "data.csv";
$array = explode("\n", file_get_contents("data.csv"));
$numbers = array();
foreach(array_chunk($array, 3) as $number){
    $numbers[] = implode(", ", $number);
}
print_r($numbers);
?>
