如何修改正则表达式以仅匹配字符串中的特定数字？

Question

Below is my code to replace all mentions with their respective profile links using tag.

Now what i need is to remove a specific mention from this string.

Say i have string "hi how are you guys???... @@[Sam Thomas:10181] @@[Jack Daniel:11074] "

now i want to remove @@[Sam Thomas:10181] from this string using his id which will be unique one ie 10181.. any regular expression to identify this whole pattern using id as specified above.

echo 'USER TAG NAME WITH PROFILE LINK<br/><hr>';
$text = "hi how are you guys???... @@[Sam Thomas:10181] @@[Jack Daniel:11074] @@[Paul Walker:11043] ";
echo 'REGULAR EXPRESSION USED: <b>/@@\[([^:]*):(\d*)\]/</b>';
echo '<br/>Sample Text<br/>';
echo $text.'<br/>';
$pattern = "/@@\[([^:]*):(\d*)\]/";
$matches = array();
preg_match_all($pattern, $text, $matches);
echo '<pre>';
print_r($matches);
echo '</pre>';
echo '<hr>';
$output = preg_replace($pattern, "<a href=\"http://localhost/$2\" class=\"tooltip\">$1</a>", $text);
echo 'FINAL OUTPUT<br/><hr>';
echo $output;
echo '<br/>==================================================================================<br/>';

\\d* matches any number - if you want to restrict the match to a certain number, replace it with that number:

$pattern = "/@@\[([^:]*):(10181)\]/";

If you expect a variation of numbers, you can use alternation :

$pattern = "/@@\[([^:]*):(10181|11074)\]/";
