substr()only matches whole strings. You are looking for preg_match().
substr()只匹配整个字符串。您正在寻找preg_match().
Update:
更新：
$name = 'hello [*kitty*],how good is today';
preg_match( '/\[(.*?)\]/', $name, $match );
var_dump( $match );
You can find the name in $match[1]. I suggest you read up on regular expressions to understand preg_match().
您可以在$match[1]. 我建议您阅读正则表达式以了解preg_match().

Try this:
尝试这个：
$matches = array();
preg_match("/\[([^]]*)\]/", 'hello [*kitty*],how good is today', $matches);
print_r($matches);
Oops, fixed it now :)
哎呀，现在修好了:)
