如何更改列表CSV，反之亦然，在PHP

Question

我有一個文本文件中像....

arfc@net.xz

editor@magazine.com

nafi@cyber.net

nau@times.com

jai@mail.com

我想在一點PHP的幫助下將其轉換爲CSV，並且我也想知道它是如何顛倒的......即從CSV到有序或無序列表.....好心幫我請:)

Answer 1

要轉換爲CSV

$data=file_get_contents("file"); 
$data =explode("\n\n",$data); 
echo implode(",",array_filter($data)); 

根據需要更新，以從CSV轉換，

$data = explode(",", file_get_contents("file")); 
echo implode("\n\n",$data); 

對於CSV多行數據，則可以使用fgetcsv()遍歷文件。例如

if (($handle = fopen("file.csv", "r")) !== FALSE) { 
    while (($data = fgetcsv($handle, 2048, ",")) !== FALSE) { 
     $num = count($data); 
     for ($c=0; $c < $num; $c++) { 
      echo $data[$c] . "<br />\n"; 
     } 
    } 
    fclose($handle); 
} 

Answer 2

<?php 
//read file 
$content = file_get_content($filteredFilePath); 

//explode contents into array 
//if you use windows or mac, newlines may be different 
//i.e: \r, \r\n 
$list = explode("\n\n", $content); 

//iterate over the items and print a HTML list 
//to generate ordered list, use: <ol> 
echo '<ul>'; 
foreach($list as $item) { 
    echo '<li>' . $item . '</li>'; 
} 
echo '</ul>'; 

編輯：我做了一些修改，採用雙換行工作。
