if ($_GET['lx'] == "1"):

else:
$file_name = $r['picurl'];
endif;
if..endif syntax
The `alternative' way to write if/elseif/else statements, using if(); elseif(); else; endif; cannot be efficiently implemented without adding a large amount of complexity to the 3.0 parser. Because of this, the syntax has been changed: Example E-5. Migration: old if..endif syntax
if ($foo);
echo "yep\n";
elseif ($bar);
echo "almost\n";
else;
echo "nope\n";
endif;
Example E-6. Migration: new if..endif syntax
if ($foo):
echo "yep\n";
elseif ($bar):
echo "almost\n";
else:
echo "nope\n";
endif;
Notice that the semicolons have been replaced by colons in all statements but the one terminating the expression (endif).
