if ($_GET['lx'] == "1"):
$file_name = $r['titlepic'];
else
$file_name = $r['picurl'];
end if
这句正确得如何写？？
if ($_GET['lx'] == "1"): $file_name = $r['titlepic'];else:$file_name = $r['picurl'];endif;
if..endif syntaxThe `alternative' way to write if/elseif/else statements, using if(); elseif(); else; endif; cannot be efficiently implemented without adding a large amount of complexity to the 3.0 parser. Because of this, the syntax has been changed: Example E-5. Migration: old if..endif syntaxif ($foo); echo "yep\n";elseif ($bar); echo "almost\n";else; echo "nope\n";endif; Example E-6. Migration: new if..endif syntaxif ($foo): echo "yep\n";elseif ($bar): echo "almost\n";else: echo "nope\n";endif; Notice that the semicolons have been replaced by colons in all statements but the one terminating the expression (endif).
