PHP 6 has goto which can be used for that.

How can this code be rewritten using goto? I downloaded a PHP 6 snapshot and tried this:

ROW: for ($i = 0; $i < 5; ++$i)
{
    print "$i: ";
    COLUMN: for ($j = 0; $j < 5; ++$j)
    {
        print "$j ";
        if ($j == 2 && $i == 4)
            goto ROW;
    }
    print "\n";
}

but the entire loop is repeated; it doesn't produce the same output as the first example. 

From http://www.php.net/~derick/meeting-notes.html#adding-goto (first result on Google for "php 6 goto"), I see that there were plans to "reuse the break keyword, and extend it with a static label.", but this does not appear to be implemented the the latest snapshot. Those meeting notes were from 2005 however. Google also found http://php6dev.blogspot.com/ but that page is currently down so I couldn't read it.

How can I use goto to act as "continue 2" or "break 2"? I also tried:

for ($i = 0; $i < 5; ROW: ++$i)
{
    print "$i: ";
    for ($j = 0; $j < 5; ++$j)
    {
        print "$j ";
        if ($j == 2 && $i == 4)
            goto ROW;
    }
    print "\n";
}

and: for ($i = 0; ROW: $i < 5; ++$i)
and: for (ROW: $i = 0; $i < 5; ROW: ++$i)

but these all report:

Parse error: syntax error, unexpected ':', expecting ')'

Did you consider this:

for ($i = 0; $i < 5; ++$i)
{
    print "$i: ";

    for ($j = 0; $j < 5; ++$j)
    {
        print "$j ";
        if ($j == 2 && $i == 4)
            goto END;
    }

    print "\n";
    END:
}

If the label needs to proceed a statement, try LABEL: noop();

Another solution could be to get the the nesting level and use:

continue $nest_level - 1;

Unfortunately, I can find no such function so this would need to be done 
manually.

If this was to be implemented (it should), then perhaps follow Java's lead for the syntax: http://docs.oracle.com/javase/specs/jls/se7/html/jls-14.html#jls-14.7

Various other languages have different implementation of this, and I'd worry PHP might accidentally end up with something like how Ruby does it (http://www.ruby-doc.org/core-2.1.3/Kernel.html#method-i-catch) which is awful.
