Simple regex - finding words including numbers but only on occasion -


i'm bad @ regex, have:

    /(@[a-za-z-]+)/

which finds words after @ symbol in textbox, need ignore email addresses, like:

    foo@things.com

however finds @things

i need include numbers, like:

    @he2foo

however finds @he part.

help appreciated, , if feel explaining regex in simple terms, that'd great :d

/(?:^|(?<=\s))@([a-za-z0-9]+)(?=[.?]?\s)/

@this (matched) regex ignores@this matches on @separate tokens tokens @ end of sentence @this. or @this? (without picking . or ?) , yes email@addresses.com ignored too.

the regex while matching on @ lets access what's after (like userid in @userid) picking regex group(1). check php documentation on how work regex groups.
