これが私のコードです

$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/>";  
    }
}

これを簡単に行うことができますstrtok

strtok()str文字列 ( ) を小さな文字列 ( ) に分割し、tokens各トークンは token の任意の文字で区切られます。つまり、「This is an example string」のような文字列がある場合、スペース文字をトークンとして使用することで、この文字列を個々の単語にトークン化できます。

例 (デモ):

$txt = 'topic: My Thesis | link: …';

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

これにより、質問に表示される出力が得られます。

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

編集: コード全体を 1 行で表すことができます。

$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);

これは、私があなたが望むと思うものの実用的な実装です:

$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";
  }
}

これを試して

<?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);
