正则表达式以匹配第一次出现的

regex to match up to first occurrence of

我有这段文字:

{{Infobox Item
|name = value
|prop2 = value
|prop3 = value
}}

它来自 mediawiki 模板。

我有以下正则表达式:

preg_match('/\{\{Infobox Item.+\n\}\}\n/s', $text, $ra);

我正在使用 PHP。

我想匹配从 {{Infobox Item}} 的第一次出现,它总是单独在一行上。上面的正则表达式将从 {{Infobox Item 匹配到另一个 {{ }} 样式块的末尾,这不是我想要的。我怎样才能做到这一点?

代码

preg_match('/{{Infobox Item.+?^}}$/sm', $subject, $regs)

正则表达式

{{Infobox Item.+?^}}$
