Question

我有一个.txt文件，格式如下：

topic: My Thesis | link: my_thesis.html |  date: 04-01-2013, 06:01 AM ~ postedby: smith ~ post: Has anyone worked on my thesis? ~ 
topic: Thesis Submission | link: thesis_submission.html |  date: 05-10-2013, 08:20 PM ~ postedby: Terry ~ post: Anyone is working on thesis submission? ~  date: 05-11-2013, 10:04 AM ~ postedby: Julia ~ post: Working on it, will submit today at any time ~  date: 05-11-2013, 04:25 PM ~ postedby: Terry ~ post: Please get reviewed before submission, Thanks! ~  date: 05-11-2013, 10:00 PM ~ postedby: Smith ~ post: Hurryup We don't have time, Its already late ~

我试图以这种方式获得它的输出，但无法实现它。有人可以帮帮我吗？

这是我的代码

$text = file_get_contents('c:\textfile.txt');
$texts = explode("\n",$text);

foreach($texts as $line) {
    $temp = explode('topic:',$line);            
    $topic = explode("|",$temp[1]); 
    echo "topic : " .$topic[0] ."<br/>"; 
    $temp = explode('link:',$line);
    $href = explode("|",$temp[1]);  
    echo "link : " .$topic[0] ."<br/>"; 
    $add = explode("|",$line);
    $adds = $add[2];    

    $rem = explode("\n",$adds);

    foreach($rem as $data) {            
        $temps = explode('date:',$data);                
        $date = explode('~',$temps[1]);     
        echo "date : " .$date[0] ."<br/>";      
        $temps = explode('postedby:',$data);        
        $postedby = explode('~',$temps[1]);
        echo "postedby: " .$postedby[0]  ."<br/>";
        $temps = explode('post:',$data);        
        $post = explode('~',$temps[1]);
        echo "post: " . $post[0] ."<br/>";  
    }
}

Answer 1

试试这个

$data="topic: My Thesis | link: my_thesis.html |  date: 04-01-2013, 06:01 AM ~ postedby: smith ~ post: Has anyone worked on my thesis? ~ 
    topic: Thesis Submission | link: thesis_submission.html |  date: 05-10-2013, 08:20 PM ~ postedby: Terry ~ post: Anyone is working on thesis submission? ~  date: 05-11-2013, 10:04 AM ~ postedby: Julia ~ post: Working on it, will submit today at any time ~  date: 05-11-2013, 04:25 PM ~ postedby: Terry ~ post: Please get reviewed before submission, Thanks! ~  date: 05-11-2013, 10:00 PM ~ postedby: Smith ~ post: Hurryup We don't have time, Its already late ~";

$data = array_map('trim',preg_split("/[|~]/",$data));
print_r($data);

编辑：您可以为整个代码添加一行。

$data = array_map('trim',preg_split("/[|~]/",file_get_contents('c:\textfile.txt')));
//Check the $parsed below. I think this is enough for adding to your db and to work with.
$parsed = array();
$cntr=-1;
for ($i=0;$i<count($data);$i++){
    $kv = explode(':',$data[$i]);
    if($kv[0]=='topic')$cntr++;
    $k = trim($kv[0]);
    if (!empty($k) && !empty($kv[1])){
        $parsed[$cntr][$k]=trim($kv[1]);
    }
}
print_r($parsed);

输出

Array
(
    [0] => Array
        (
            [topic] => My Thesis
            [link] => my_thesis.html
            [date] => 04-01-2013, 06
            [postedby] => smith
            [post] => Has anyone worked on my thesis?
        )

    [1] => Array
        (
            [topic] => Thesis Submission
            [link] => thesis_submission.html
            [date] => 05-11-2013, 10
            [postedby] => Smith
            [post] => Hurryup We don't have time, Its already late
        )

)

Answer 2

您可以使用strtok

轻松完成此操作

strtok()将字符串（str）拆分为较小的字符串（tokens），每个标记由令牌中的任何字符分隔。也就是说，如果您有一个类似“这是一个示例字符串”的字符串，您可以使用空格字符作为标记将此字符串标记为其单个单词。

示例（demo）：

$txt = 'topic: My Thesis | link: …';

for ($t = strtok($txt, "|~"); $t !== false; $t = strtok("|~")) {
    echo trim($t), PHP_EOL;
}

这将显示您在问题中显示的输出。

Answer 3

Here's a working implementation of what I think you want：

$lines = explode("\n", $input);
foreach($lines as $line)
{
  echo "----\n";
  $elements = preg_split('#[~|]#', $line);
  foreach($elements as $element)
  {
    list($key, $value) = array_map('trim', explode(':', $element));
    echo "$key -> $value\n";
  }
}

Answer 4

试试这个

<?php
$lines = file("textfile.txt");
//print_r($lines);

$data = array();
for($i = 0; $i < count($lines); $i += 2)
{
    $data[] = array_map('trim',preg_split("/[\|~]/",$lines[$i]));

}
print_r($data);
?>
