如何使用 PHP 打印 CSV 文件的行？

Question

这是我正在使用的代码，但它并没有准确输出我想要的内容。<?php$file = fopen("ad.csv","r");while(! feof($file))  {  print_r(fgetcsv($file));  }fclose($file);?>这是它当前输出的内容：Array ( [0] => cn [1] => mail [2] => telephonenumber [3] => uid ) Array ( [0] => [1] => [2] => [3] => ) Array ( [0] => admin [1] => [2] => [3] => ) Array ( [0] => Isaac Newton [1] => [e-mail] [2] => [3] => newton ) Array ( [0] => Albert Einstein [1] => [e-mail] [2] => 314-159-2653 [3] => einstein ) Array ( [0] => Nikola Tesla [1] => [e-mail] [2] => [3] => tesla ) Array ( [0] => Galileo Galilei [1] => [e-mail] [2] => [3] => galieleo ) Array ( [0] => Leonhard Euler [1] => [e-mail] [2] => [3] => euler ) Array ( [0] => Carl Friedrich Gauss [1] => [e-mail] [2] => [3] => gauss ) Array ( [0] => Bernhard Riemann [1] => [e-mail] [2] => [3] => riemann ) Array ( [0] => Euclid [1] => [e-mail] [2] => [3] => euclid ) Array ( [0] => Mathematicians [1] => [2] => [3] => ) Array ( [0] => Scientists [1] => [2] => [3] => ) Array ( [0] => read-only-admin [1] => [2] => [3] => ) Array ( [0] => Italians [1] => [2] => [3] => ) Array ( [0] => Test [1] => [2] => [3] => test ) Array ( [0] => Chemists [1] => [2] => [3] => ) Array ( [0] => Marie Curie [1] => [e-mail] [2] => [3] => curie ) Array ( [0] => Alfred Nobel [1] => [e-mail] [2] => [3] => nobel ) Array ( [0] => Robert Boyle [1] => [e-mail] [2] => 999-867-5309 [3] => boyle ) Array ( [0] => Louis Pasteur [1] => [e-mail] [2] => 602-214-4978 [3] => pasteur ) Array ( [0] => No Group [1] => [e-mail] [2] => [3] => nogroup ) Array ( [0] => FS Training [1] => [e-mail] [2] => 888-111-2222 [3] => training ) Array ( [0] => FS Training [1] => [e-mail] [2] => 888-111-2222 [3] => jmacy )换句话说，这几乎就像将我所有的 CSV 数据添加到一个多维数组中一样......

顺便说一句，在 php 7.2 中这也可以工作：

    <?php

    $row = 1;

    if (($handle = fopen("ad.csv", "r")) !== FALSE) {

        while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) {

            echo ($data[0].",".$data[1].",".$data[2].",".$data[3]."\n");

        }

        fclose($handle);

    }

    ?>

此外，.csv 数据上的引号应包含所有数据，例如：

"Isaac Newton","[e-mail]",,"newton"

"Albert Einstein","[e-mail]","314-159-2653","einstein"

"Nikola Tesla","[e-mail]",,"tesla"

"Galileo Galilei","[e-mail]",,"galieleo"
