grab category value from mediawiki markup in php

Question

I am working on retriving category values from a wiki markup text in loop, could not grab category values from the markup using regex match in php

The Markup Text Contains the category values as

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

Here's what I have tried so far

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

This is the output

 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
)

But I'm trying to get output array with only category values after colon , i.e.

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

And so on.

What changes should i make to my regex to get only category values filled up in the $mathces array Or should i use oter php function instead of preg_match ?

Kindly note that, the $input_wiki_markup also containes other text around the [[Categpry:xyz]] tags

Answer 1

all you need was an all

$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);
           }

OUTPUT:

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
    )
