移除;；在字符串中

Question

我有绳子

;{card}(Secrets of Dark Magic);;{card}(Secrets of Dark Magic);;{card}(Secrets of Dark Magic);;{card}(Secrets of Dark Magic;;Called by the Grave);;{card}(Secrets of Dark Magic;;Called by the Grave;;Secrets of Dark Magic)

我想移除;；在这里{卡}(黑暗魔法的秘密；被坟墓召唤)(不;；外面)

结果我想要

   ;{card}(Secrets of Dark Magic);;{card}(Secrets of Dark Magic);;{card}(Secrets of Dark Magic);;{card}(Secrets of Dark Magic;Called by the Grave);;{card}(Secrets of Dark Magic;Called by the Grave;Secrets of Dark Magic)

我尝试了下面的代码，但它删除了字符串中的所有;；！

$search = ';;';
$string = preg_replace("/($search)/", ";", $string); 

Answer 1

我们可以在这里使用preg_replace_callback来针对括号(...)中出现的所有文本。然后，在每个匹配项上，从;;到单个;执行一个简单的字符串替换。

$input = ";{card}(Secrets of Dark Magic);;{card}(Secrets of Dark Magic);;{card}(Secrets of Dark Magic);;{card}(Secrets of Dark Magic;;Called by the Grave);;{card}(Secrets of Dark Magic;;Called by the Grave;;Secrets of Dark Magic)";
$output = preg_replace_callback("/\(.*?\)/", function($matches) {
    return str_replace(";;", ";", $matches[0]);
}, $input);
echo $input;
echo "\n";
echo $output;

这些指纹：

；{card}(黑暗魔法的秘密)；；{card}(黑暗魔法的秘密；被坟墓召唤)；{card}(黑暗魔法的秘密；被坟墓召唤；；黑暗魔法的秘密)；{card}(黑暗魔法的秘密)；{card}(黑暗魔法的秘密；被坟墓召唤)；{card}(黑暗魔法的秘密；被坟墓召唤；黑暗魔法的秘密)
