When posting from JS, PHP (5.3.8) returns some line returns in excess. For example:
if (isset($_POST['postId']) && $_POST['postId'] == "test") {
echo 'ok';
}
returns ok↵↵↵
Is this by design? How can I get rid of those line returns?
No, this is not by design. You have three newline output.
Try to delete the close tag of php
?>, if you don’t have any html after php code.Another way is just put
exit;right afterecho, you won’t get newline again.
