Search for @mentions in a string

Trying to replace all @mention occurrences with an anchor tag while I have:

$comment = preg_replace('/@([^@ ])? /', '<a href="/$1">@$1</a> ', $comment);

Take the following sample line:

"@name kdfjd fkjd as@name @ lkjlkj @name"

So far so good, but I want to ignore this single "@" character. I tried using "+" and "{2,}" after "[^ @]", which I thought would provide a minimal number of matches, but it does not work.

Replace the question mark quantum ( ?) ("optional") and add +("one or more") after your character class:

@([^@ ]+)
