I have a trouble with the CCaptcha widget. Image is corrupted. Headers are looks right. When I tried to list an image as a text, I didn't find any text inclusions, it's looks like as a usual PNG content.
When I created an another webapp on the same framework instance, CCaptcha works correctly, but in my first webapp have a trouble.
In my case GD library is used. Access filter is not used.
I'd found an error. It was a space before PHP open tag in top of base controller file. And now the bug is fixed.

I have seen this code in my header. php file, i don't know what is the use of this tag. They also mentioned initial scale=1.0 like that so can you anyone explain me what the use of that code.
It's used to set the initial scale of the layout. If the initial scale is set to 1, then the layout will be viewed at a scale of 1:1 (no zooming). It can be adjusted as well as changed to a set width.

as we all know,there is a data type 'resouce' in php!I sometimes can encounter this data type!but I have some problems about this type!
when I have a db connect,I print the data type,it displays"resource(4, mysql link)",
when I create a image,I print the data type,it displays "resource(2, gd)"
i want to know what the number eg.'4','2' means in the "()".
sorry for my bad englis!
When you see resource(4, ...) what that means is that PHP is keeping a reference to a more complex object that isn't a normal PHP object, and thus can't be manipulated directly. It's typically used by libraries that interface with non-PHP code (such as database client libraries and the GD library).
The number is simply the ID number of that particular external object.
These resources are managed by the external library and only really given to PHP as an indirect reference; they only have meaning to the library code that created them.

I'm using the custom theme of recaptcha, and the designer want that the recaptcha's image will be smaller in the width but not in the height. Is there a way to do it?
reCAPTCHA is served via an Iframe on a different domain, therefore you cannot alter what it serves-up.
If you could alter it, so could malicious scripts.

http://www.aliexpress.com/item/NEW-7-Android-2-3-256MB-DDR2-4GB-NAND-Flash-7-inch-tablet-pc/498159194.html - I got this link
Here you can see a buttons: bundle, color
If you click some of them the price will change, but the question is how can I parse that behaviour to my page via php?
The problem is that I can't understand where is javascript code that executes this, or how to find it, maybe someone got ideas about that?
Inspecting that page's source code I can see that the skuProducts variable in javascript contains this information encoded into a JSON-string. You can't really run this javascript code on your webserver, so you'll have to devise another way to get that variable's value - and then you can use json_decode() to get the contents.
Note that changing the amount of items results in an AJAX call to a shipping costs calculator. You could probably simulate that, but I'm not sure that webshop would like that (and it might be illegal).

can you please help with my project, i'm just newbie on PHP programming.
i had an excel reader php, it's working good, converting my excel file into PHP .
i want hopefully to detect the newest excel file in the folder then convert it into html using excel reader.
is that possible?
hope you can help me, thank you so much
You can iterate over a directory in PHP by using dir (http://nl1.php.net/manual/en/function.dir.php )and then use filemtime to check when the file was modified (http://php.net/manual/en/function.filemtime.php ).
As for converting to HTML - I assume that you have your Excel file loaded into PHP data structures (objects or arrays for example); if so, you can easily generate HTML using echo statements or - perhaps a bit more advanced - a teplating system.
