The page I am working on has a javascript function executed to print parts of the page. For some reason, printing in Safari, causes the window to somehow update. I say somehow, because it does not really refresh as in reload the page, but rather it starts the "rendering" of the page from start, i.e. scroll to top, flash animations start from 0, and so forth. The effect is reproduced by this fiddle: http://jsfiddle.net/fYmnB/ Clicking the print button and finishing or cancelling a print in Safari causes the screen to "go white" for a sec, which in my real website manifests itself as something "like" a reload. While running print button with, let's say, Firefox, just opens and closes the print dialogue without affecting the fiddle page in any way. Is there something with my way of calling the browsers print method that causes this, or how can it be explained - and preferably, avoided? P.S.: On my real site the same occurs with Chrome.

You can cast a variable to an array in this sense (albeit there is no need to in PHP.)
ReplyDelete$var = (array)$arr;
Additionally, while you can do the above to set the variable $arr into $var and force it to be an array, there is little to no point in doing such. In PHP, most things we may call "data types" as programmers are simply non-existent. Any variable can be a double, float, string... anything all at once. They are almost completely inter-changeable.
See: http://php.net/manual/en/language.types.php
$a = (array) $a;
ReplyDeleteis the answer.
Alternatively you could use settype:
ReplyDeletesettype($a, "array");
For expliciting the variable type. It's exactly the same as what happens with a typecast behind the scenes. (More useful for group-wise typecasting e.g. in loops.)
I would write your could snippet like this (short and you read it and know exactly what is happening):
ReplyDelete$a = is_array($v) ? $v : array($v);
