正则表达式从PHP中的字符串中获取所有@提到的用户数据

Question

I have below string. This string having data (@[ID:username__FULLNAME]) of three users mentioned. I want to extract them. I have tried below code but not getting desired results.

ID is integer type
username and FULLNAME may contain numbers, letter and all kind of special chars.


$t = 'Hi @[4232:mark__MΛRK ATTLEY] how are you ? 
    Hi @[4232:ryan__RYΛN вυηту] how are you ? 
    Hi @[4232:david__DΛVID शाहिद ] how are you ? 
    ';

My PHP CODE:

$pattern = "|(?:(@\[[0-9]+:[\s\S(?!\])]+\]*))|";
preg_match_all($pattern, $string, $mentionList, PREG_PATTERN_ORDER);
print_r($mentionList);

Current Result:

Array
(
    [0] => Array
        (
            [0] => @[4232:mark__MΛRK ATTLEY] how are you ? 
    Hi @[4232:ryan__RYΛN вυηту] how are you ? 
    Hi @[4232:david__DΛVID शाहिद] how are you ? 

        )

    [1] => Array
        (
            [0] => @[4232:mark__MΛRK ATTLEY] how are you ? 
    Hi @[4232:ryan__RYΛN вυηту] how are you ? 
    Hi @[4232:david__DΛVID शाहिद] how are you ? 

        )

)

Expected Result:

Array
(
    [0] => Array
        (
            [0] => @[4232:mark__MΛRK ATTLEY]
            [1] => @[4232:ryan__RYΛN вυηту]
            [2] => @[4232:david__DΛVID शाहिद ]
        )

)

Can someone help me getting the desired results?

Thanks.

You can use the following regex: @\[.+\] (demo) that gets you all you have in [] plus the front @.
