Here's what's happening; a list in scalar context will return its last element.

@array[0..2] will return a list, and in @{}'s scalar context, the last element will be returned, which is the last array ref, that's why you get the last array's item 3 only.

Here's a workaround:

my @array=( [0,1,2,3,4],
            [25,26,27,28,29],
            [10,11,12,13,14]
            );
print @{@array[$_]}[3] for 0 .. 2;

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
Want more info? How to link or How to display code and escape characters are good places to start.
