php - 从 php 中的 mediawiki 标记中获取类别值

Question

我正致力于从循环中的 wiki 标记文本中检索类别值，无法在 php 中使用正则表达式匹配从标记中获取类别值

标记文本包含类别值作为

$input_wiki_markup = "
[[Category:Google]]
[[Category:Tricks]]
[[Category:Google Search]]
[[Category:Filters]]
[[Category:Search]]
[[Category:Tips]]";

到目前为止，这是我尝试过的

$matches = array();
           if(preg_match("/\[\[(Category):(.+)*\]\]/i", $input_wiki_markup, $matches)){
               print_r($matches);
           }

这是输出

 Array
(
    [0] => [[Category:Google]][[Category:Tricks]][[Category:Google Search]][[Category:Filters]][[Category:Search]][[Category:Tips]]
    [1] => Category
    [2] => Google]][[Category:Tricks]][[Category:Google Search]][[Category:Filters]][[Category:Search]][[Category:Tips
)

但我试图在冒号之后获取仅包含类别值的输出数组，即

 Array
(
    [0] => Google
    [1] => Tricks
    [2] => Google Searcg
)

等等。

我应该对我的正则表达式进行哪些更改以仅获取 $mathces 数组中填充的类别值或者我应该使用其他 php 函数而不是 preg_match ？

请注意，$input_wiki_markup 还包含 [[Categpry:xyz]] 标签周围的其他文本

你所需要的只是一个全部

$input_wiki_markup="
[[Category:Google]]
[[Category:Tricks]]
[[Category:Google Search]]
[[Category:Filters]]
[[Category:Search]]
[[Category:Tips]]
";

$matches = array();
           if(preg_match_all("/\[\[(Category):(.+)*\]\]/i", $input_wiki_markup, $matches)){
               print_r($matches);
           }

输出:

Array
(
[0] => Array
    (
        [0] => [[Category:Google]]
        [1] => [[Category:Tricks]]
        [2] => [[Category:Google Search]]
        [3] => [[Category:Filters]]
        [4] => [[Category:Search]]
        [5] => [[Category:Tips]]
    )

[1] => Array
    (
        [0] => Category
        [1] => Category
        [2] => Category
        [3] => Category
        [4] => Category
        [5] => Category
    )

[2] => Array
    (
        [0] => Google
        [1] => Tricks
        [2] => Google Search
        [3] => Filters
        [4] => Search
        [5] => Tips
    )
