PHP正则表达式并比较字符串中的变量

Question

我有一个棘手的问题，好像我被卡住了。 我有一个想法，但在实践中却不知道如何做。

我想做的是将.txt文件中的字符串转换为另一种格式（使用正则表达式和变量？）。 主要问题是当我需要转换带有// comments标记的行时。

注意： “ ... villainx调用$ x”的计算方式与原始格式和应转换为的格式不同。 这就是我需要认真帮助的问题。

示例：这需要转换...

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 ]

...对此：

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 ]

另一个例子：

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 ]

这是整个手形的完整示例。 Txt文件可能包含数百只手。 我已经设法preg_replace基本上除了上面的所有其他问题。 我迷路了。 请帮我！ ：D

Answer 1

您可以使用preg_match提取美元价值并用preg_replace重新排列字符串吗？

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

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

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

唯一不会做的就是忽略声明每个“ seat”开头的行，因此您可能需要先过滤掉这些行[简单的strpos（$ stringToMatch，'Seat'）可能就足够了，不是很优雅虽然]。

Answer 2

好，我再去。 这将以某种php / psuedocode的形式编写。

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
    }
}

嗯，它相当粗糙而且可以使用，我可能不会将其归类为解析器，但是无论如何，它确实可以计算出所需的所有值。 2个$ betMade变量应以所需的值结尾。

编辑：我刚刚注意到，如果没有人加注并且每个人都只是跟注或弃牌（并且如果每个人都只是弃牌或其他什么都可能会死得很惨），那是行不通的。 它确实需要做更多的工作，但这是总的要点-称其为半答案。 抱歉。
