從文件中讀取Q＆A的對？

Question

我正在尋找創建一個簡單的文本文件，充滿了問題和單一的答案。基本佈局思路是：

[Q] Question 1 
[A] Answer 1 
[-] 
[Q] Question 2 
[A] Answer 2 
[-] 

每個答案之後是一個分隔符號[ - ]表明，Q/A組合是完整的。答案可以運行多行和/或包含一些基本的HTML。

如：

[Q] What is PHP ? 
    [A] <b>PHP</b> is a server-side scripting language designed for web development but also used as a general-purpose programming 
language.<br/>PHP is now installed on more than 244 million websites 
and 2.1 million web servers.<a href='#'>[2]</a><br/>Originally created 
by Rasmus Lerdorf in 1995, the reference implementation of PHP is now 
produced by The PHP Group 
    [-] 
    [Q] Question 2 
    [A] Answer 2 
    [-] 

的文本文件，將手工寫入和存儲在本地服務器上。所以如果需要的話可以改變佈局。但我確實希望能夠在格式中使用一些HTML。

我想嘗試做的是將這個文件讀取到一個php頁面，並通過每個Q/A對循環並將它們呈現在屏幕上。

答問會輸出類似於：

<a href="#" class="question">QUESTION</a> 
<div class="answer"> 
<strong>[Q] QUESTION</strong><br/> 
[A]ANSWER 
</div> 

有人點我在正確的方向讀取對，然後輸出它們。

謝謝:)

UPDATE： 這是我到目前爲止有： 問題：

[Q] Question 1 
[A] Answer 1 
[-] 
[Q] Question 2 
[A] Answer 2 
[-] 
[Q] Question 3 
[A] Answer 3 
[-] 
[Q] Question 4 
[A] <b>PHP</b> is a server-side scripting language designed for web development but also used as a general-purpose programming language.<br/>PHP is now installed on more than 244 million websites and 2.1 million web servers.<a href='#'>[2]</a><br/>Originally created by Rasmus Lerdorf in 1995, the reference implementation of PHP is now produced by The PHP Group 
[-] 
[Q] Question 5 
[A] Answer 5 
[-] 
[Q] Question 6 
[A] Answer 6 
[-] 

腳本：

<?php 
$handle = fopen("questions.txt","r"); 

if ($handle) { 
    while (($line = fgets($handle)) !== false) { 
     if (substr($line,0,3)==="[Q]") { 
      echo "<a href='#' class='question'>$line</a>"; 
      $question = $line; 
     } 

     if (substr($line,0,3)==="[A]") { 
      echo "<div class='answer'>"; 
      echo "<strong>$question</strong><br/>"; 
      echo "$line</div>"; 
     } 

     if (substr($line,0,3)==="[-]") { 
     echo "<br/>"; 
     continue; 
     } 

    } 
} else { 
    echo "Unable to open file"; 
} 

?> 

這可行，但它需要每個問題都是一條線。理想情況下，我想確保它們與Q/A對匹配，答案可以分成多行。

Answer 1

好吧，我們假設[Q]，[A]和[-]標籤將始終在一行的開頭。

我會設置一個變量，它保留內存中解析php腳本的文件part，然後讀取該行。這很簡單。另外，我以不同的方式管理$question。這應該做的伎倆。

<?php 
$handle = fopen("questions.txt","r"); 
$part = 0; 
$question = ""; 
if ($handle) { 
    while (($line = fgets($handle)) !== false) { 
     if (strlen($line) > 2) { 
      if (substr($line,0,3)==="[Q]") { 
       $part = 0; 
       echo "<a href='#' class='question'>".$line; 
       $question = $line; 
      } 

      else if (substr($line,0,3)==="[A]") { 
       $part = 1; 
       echo "</a><div class='answer'>"; 
       echo "<strong>".$question."</strong><br/>"; 
       $line = substr($line, 3, strlen($line)-3); 
       echo $line; 
      } 

      else if (substr($line,0,3)==="[-]") { 
       echo "</div><br/>"; 
       continue; 
      } 

      else { 
       echo $line; 
       if ($part == 0) 
        $question .= $line; 
      } 
     } 
     else { 
      echo $line; 
      if ($part == 0) 
       $question .= $line; 
     } 
    } 
} 
else { 
    echo "Unable to open file"; 
} 
?>
