It should be noted that despite what it may look like to some people, you *cannot* imitate Javascripts shorthand assignment notation (which is similar to ternary notation, though it omits the middle part). In JavaScript, you can write: var text_var = some_var || new String(); That will assign some_var to text_var if it's a "true" statement (aka, if (some_var) would be true), otherwise it would assign text_var a new String() object. The PHP documentation gives the slight appearance as if writing: $text_var = $some_var or new String(); would do the same thing, however it does not - and it's too bad, because it would be useful and more readable than the new shorthand ternary format, valid for PHP 5.3+ only: $text_var = $some_var ?: new String(); Unfortunately, it appears that once the "or" condition is seen, it forgets what context it was in and expects a completely new statement for evaluation, rather than a continuation (as is possible in JavaScript). ---- Server IP: 69.147.83.197 Probable Submitter: 99.241.132.158 ---- Manual Page -- http://www.php.net/manual/en/language.operators.logical.php Edit -- https://master.php.net/note/edit/89379 Del: integrated -- https://master.php.net/note/delete/89379/integrated Del: useless -- https://master.php.net/note/delete/89379/useless Del: bad code -- https://master.php.net/note/delete/89379/bad+code Del: spam -- https://master.php.net/note/delete/89379/spam Del: non-english -- https://master.php.net/note/delete/89379/non-english Del: in docs -- https://master.php.net/note/delete/89379/in+docs Del: other reasons-- https://master.php.net/note/delete/89379 Reject -- https://master.php.net/note/reject/89379 Search -- https://master.php.net/manage/user-notes.php
