You are also allowed to jump backwards with a goto statement. To run a block of goto as one block is
as follows:
example has a prefix of iw_ to keep label groups structured and an extra underscore to do a
backwards goto.
Note the
iw_end_gt to get out of the labels area
<?php
$link = true;
if ( $link ) goto iw_link_begin;
if(false) iw__link_begin:
if ( $link ) goto iw_link_text;
if(false) iw__link_text:
if ( $link ) goto iw_link_end;
if(false) iw__link_end:
goto iw_end_gt;
if (false) iw_link_begin:
echo '<a href="#">';
goto iw__link_begin;
if (false) iw_link_text:
echo 'Sample Text';
goto iw__link_text;
if (false) iw_link_end:
echo '</a>';
goto iw__link_end;
iw_end_gt:
?>
