Perl vs PHP (a bit of credit to PHP)

Just read this blog post. Comments are disabled, so I thought I'd add a blog post.

There are endless ways we can sneer at PHP's deficiencies, but since 5.3 PHP already supports anonymous subroutines, via the function (args) { ... } syntax. So:

$longestLine = max(
    array_map(
        create_function('$a', 'return strlen($a);'), 
        explode("\n", $str)
    )
);

can be rewritten as:

$longestLine = max(
    array_map(
        function($a) { return strlen($a); }, 
        explode("\n", $str)
    )
);

though the example is not a good one since it might as well be:

$longestLine = max(
    array_map(
        'strlen',
        explode("\n", $str)
    )
);
