regular expression to match between [ and ]

Question

I have a string like

[gallery GALLERYNAME] [gallery GALLERYNAME]

the GALLERYNAME indicates a name of a gallery

What would a regular expression looks like to match this string?

Answer 1

\[gallery ([^\]]+)\]

Answer 2

<?php
    preg_match( "@\[gallery ([^\]]+)\]@", "foo [gallery GALLERYNAME] bar", $match );
    var_dump( $match );
    // $match[ 1 ] should contain "GALLERYNAME"
?>

As an alternate:

<?php
    preg_match_all( "@\[gallery ([^\]]+)\]@m", "
        foo [gallery GALLERYNAME1] bar
        foo [gallery GALLERYNAME2] bar
        foo [gallery GALLERYNAME3] bar
        ", $match );
    var_dump( $match );
    // $match[ 1 ] should contain an array containing the desired matches
?>

Answer 3

要匹配“GALLERYNAME”：

^\[gallery\s([A-Z]+)\]$
