不是試圖使用單個正則表達式對數字/非數字進行排序，而是創建一個正則表達式來匹配您的上下文，然後在結果數組上使用回調函數。

preg_match_all("~:\h*(\d+(?:['.]\d+)+)~", $str, $matches); 

$results = 
    array_map(function($n) { 
    return number_format(strtr($n, array("'"=>'')), 2, '.', ''); 
    }, $matches[1]); 

print_r($results); 

eval.in

我不是PHP大師，但已經給出的評論似乎是一個很好的方向。對於每個模板，你可以簡單地針對每行運行下面的正則表達式：

Total reservation amount:\s(.*) 

我會認爲這場比賽上面將存入名爲$num一個PHP變量。您可以將它投射到double，然後根據需要使用它，例如

$num = 1'699.200; 
$num = str_replace("'", "", $num); 
$double_val = doubleval($num) 

既然你刮模板是他們自己可能都通過一個（確定性）計算機程序產生的，你不應該有應對隨機格式。相反，應該有一組格式，你可以通過查看一些模板來預期。
