以下是测试代码：
preg_replace_callback() 函数处理较长字符串时，出现了 PREG_JIT_STACKLIMIT_ERROR 错误。当匹配的字符数超过 2000 个时，该函数将无法正常工作（不是指字符串长度）。我已经阅读了一些资料，发现这是由于正则表达式效率低下导致的，但我无法简化我的正则表达式。以下是我的正则表达式：
/\{@([a-z0-9_]+)-((%?[a-z0-9_]+(:[a-z0-9_]+)*)+)\|(((?R)|.)*)@\}/Us
它应该匹配如下字符串：1)
{@if-statement|echo this|echo otherwise@}
2) {@if-statement:sub|echo this|echo otherwise@}
3) {@if-statement%statament2:sub|echo this@}
以及像这样嵌套的：4)
{@if-statement|echo this|
{@if-statement2|echo this|echo otherwise@}
@}
我尝试将其简化为：
/\{@([a-z0-9_]+)-([a-z0-9_]+)\|(((?R)|.)*)@\}/Us
但似乎错误是由 (((?R)|.)*) 部分引起的。有什么建议吗？以下是测试代码：

var_dump($parsed_view); // NULL
ini_set('pcre.jit', false);是正确的方法...这就像在想要隐藏错误时使用@一样。 - instead
