PHP正則表達式和字符串

Question

比較變量我有一個棘手的問題，似乎就像我卡住了。我有一個想法如何繼續，但不知道如何在實踐中做到這一點。

我想要做什麼是轉換.txt文件爲另一種格式中的字符串（使用正則表達式和變量？）。主要問題是當我需要轉換那些標有//註釋的行時。

注意：「... villainx調用$ x」的計算方式在原始方式和格式上應該轉換爲不同的格式。這就是我需要一些嚴重幫助的問題。

舉例： 這需要轉換...

HERO posts small blind $0.50. 
villain4 posts big blind $1.00.  
** Dealing down cards ** 
Dealt to HERO [ 7s 8c 5d 8d ] 
villain1 calls $1.00 
villain2 raises to $3.00 // total sum a player raises to 
villain3 calls $3.00 
HERO calls $3.00 
villain4 calls $3.00 
villain1 calls $3.00  // total sum a player calls whether he has put money in to the pot before (as he has -- $1 call, first to act) 
** Dealing Flop ** [ 9c, Ah, Jh ] 

...這樣的：

HERO posts small blind [$0.50 USD]. 
villain4 posts big blind [$1.00 USD].  
** Dealing down cards ** 
Dealt to HERO [ 7s 8c 5d 8d ] 
villain1 calls [$1.00 USD] 
villain2 raises [$3.00 USD] // total sum a player raises to 
villain3 calls [$3.00 USD] 
HERO calls [$2.50 USD]  // a sum player calls = last raise ($3) - money put in (=$0.50 small blind) 
villain4 calls [$2.00 USD] // $3 - $1 (big blind) 
villain1 calls [$2.00 USD] // $3 - $1 (the call first to act) 
** Dealing Flop ** [ 9c, Ah, Jh ] 

又如：

HERO posts small blind $0.50. 
villain4 posts big blind $1.00.  
** Dealing down cards ** 
Dealt to HERO [ 7s 8c 5d 8d ] 
villain1 bets $5.50 
villain2 raises to $20.00 
villain3 raises to $40.00 
villain1 calls $40.00 //THIS NEEDS TO BE "calls $34.50" 
villain2 calls $40.00 //THIS NEEDS TO BE "calls $20.00" 
** Dealing Flop ** [ 9c, Ah, Jh ] 

和這裏的完整的例子整隻手應該看起來如何。 txt文件可能包含數百手。我設法基本上除了上面提到的所有其他問題之外，我迷路了。請幫幫我！ ：d

編輯2我真正的問題：加入另一個例子

Answer 1

你可以使用的preg_match拉出美元價值和重新安排串用preg_replace？

$regex = '/(\$[0-9.]+)/'; 

$matched = preg_match($regex, $stringToMatch, $matches); 

if($matched > 0) 
{ 
    $output string = preg_replace($regex, '['.$matches[0].' USD]', $stringToMatch); 
} 

這不會做的唯一的事情就是忽略開頭，你聲明每個「座位」，所以你可能需要篩選出那些第[簡單strpos（$ stringToMatch，「座位」）可能行就夠了，雖然不是很高雅]。

Answer 2

好吧，我有另一個去。這將寫在一種PHP/psuedocode的東西。

while($line = get the next line) 
{ 
    if($line contains 'seat') 
    { 
     $player = get player from $line 
     $pool = get player pool from $line 

     $bettingMatrix[$player]['pool'] = $pool; 
    } 
    else if($line contains 'blind') 
    { 
     $player = get player from $line 
     $betValue = get blind value from $line 

     $bettingMatrix[$player]['betTotal'] = $betValue 
     $bettingMatrix['pot'] += $betValue //keep a sum of the pot 
    } 
    else if($line contains 'raises') 
    { 
     $player = get player from $line 
     $betValue = get value from $line 
     $betMade = $betValue - $bettingMatrix[$player]['betTotal']; //actual amount raised by 
     $bettingMatrix[$player]['betTotal'] = $betValue //$line contains total bet this hand (shortcut) 
     $bettingMatrix['raiseValue'] = $betMade 
     $bettingMatrix['pot'] += $betMade //keep a sum of the pot 
    } 
    else if($line contains 'calls') 
    { 
     $player = get player from $line 
     //if player has called, can work out bet from raiseValue 
     $betMade = $bettingMatrix['raiseValue'] 
     $bettingMatrix[$player]['betTotal'] += $betMade 
     $bettingMatrix['pot'] += $betMade //keep a sum of the pot 
    } 
    else if(substr($line, 0, 3) == ' Wins ') //probably do something about players named Wins :) 
    { 
     //assume all bets resolved 
     foreach($bettingMatrix[$player]) 
     { 
      update pool. 
      zero betTotal 
     } 
     zero pot, zero raiseValue 
    } 
} 

呃，這是相當粗糙和準備好了，我可能不會階級作爲一個解析器正因爲如此，但它確實只是工作，你需要的所有值，我想反正。 2 $ betMade變量應該以您想要的值結尾。

編輯：我剛剛注意到，如果沒有人提出，每個人都只是調用或摺疊（也可能死可怕，如果大家只是摺疊或其他），它完全不是那麼回事。它確實需要更多的工作，但它是一般的要點 - 將其稱爲半答案。抱歉。
