PHP - Debate Type Box

Hey

In my spare time, I am working on my PHP framework.
Now, to help with development and quickly discover where I miss a type cast, I have adopted to check all parameters that are passed to a method using a function.

For instance:

            public function __construct(&$target = null, $depth = 1){
            $this->validateArguments(
                array(1 => 'int'),
                array(1 => $depth)
            );



And the code that triggers the exception:
        public function testPhpFreakType(){
            $obj = 1;
            $p = new Xcms_DataStructures_Pointer($obj, "1");
        }


Code: [Select]

I think this speeds up my development quite a bit, because I can catch errors very early in the development process.
I can give multipe possibilities of what is allowed for each parameter, not just a single possibility. Also, it is possible to register custom type/validity-checks on both global and local scope.

One thing I do worry about, however, is the the performance. Of course, I could just make the funciton do nothing in production code, if it takes too much time, or I could write a script to remove all calls to that function.

When I started learning python a while back, the concept to just code to interfaces instead of types seemed very intuitive and made my code much more flexible. Of course that is what I do with PHP as well, but I it's not entirely the same. So now, coming back at my PHP code and having introduced features of static languages such as type checking, I worry about whether that is the right approach.

What are your thoughts on the matter?

Is it not possible to get the mime type for a file uploaded using php? Am I going to be forced to use Pear? Php can read the mime type from an image, so why not from any file??

Is there a way to find out what the array type is?

Example:
Code: [Select]
$array1 = array('red', 'pizza', '14');
$array2 = array('color' => 'red', 'food' => 'pizza', 'age' => '14');

if(is_recursive($array1)){
     return TRUE;
} else if(is_multidimensional($array2){
     return TRUE;
} else {
     return FALSE;
}

Long story short, this is my code:

Code: [Select]
<input type=radio id='s1' value='1' onclick='showPreview(1)' name='star' $value><label for='s1'><img src='style_images/1/icons/1.png'></label>
<br>
<input type=radio id='s2' value='2' onclick='showPreview(2)' name='star' $value><label for='s2'><img src='style_images/1/icons/2.png'></label>
<br>
<input type=radio id='s3' value='3' onclick='showPreview(3)' name='star' $value><label for='s3'><img src='style_images/1/icons/3.png'></label>
<br>
<input type=radio id='s4' value='4' onclick='showPreview(4)' name='star' $value><label for='s4'><img src='style_images/1/icons/4.png'></label>
<br>
<input type=radio id='s5' value='5' onclick='showPreview(5)' name='star' $value><label for='s5'><img src='style_images/1/icons/5.png'></label>

Somehow I need to try to get my $value to equal 'checked' based upon my "star" variable:


So I choose #5, which is
<input type=radio id='s5' value='5' onclick='showPreview(5)' name='star' $value>

and now my "star" value is set to 5, (I updated it through my db) how do I make $value become 'checked'  when I have 4 others input type=radio's that it will check also? I only need the #5 one checked as that is one that I chose.  The problem is, I have 70 of these input type Radio's and if I use $value on every one it will not show them all checked instead of just the 1 i chose

Is there any possible way to determine a drive type (e.g., hard disk, dvd drive, usb drive, etc.) and partition type (e.g., NTFS, CDFS, ext3, etc.) in php without the use of COM and importing OS resources? I ask, because I am developing a custom system explorer for a web application. I already know how to detect drives, drive size/usage and associated drive letters, but am curious if any built-in functions of php can do this. Any help is appreciated.

Hello,

Does anyone know how may i detect the Connection type by user IP?

Broadband etc.

Hi everyone,

Can anyone give me any pointers towards how to create a form like the listing add one on ebay? Basically the form fields are displayed depending on what type of product you have, I basically need something very similar where I have multiply categories but wish to have different inputs for each type?

Many thanks

I was wondering if there was a way or if it's even possible to determine the type of a proxy using php. When I say type I mean http, socks4 or socks5.

Using cURL I think it's safe to assume that if a proxy returns a code of 200 then that proxy is good and http, correct?

However, how would I go about determining the type of proxies I have in a list, assuming they are good and socks4 and/or socks5?

Hi friends how does this types of array operate ? pls help, I am repeatedly facing this code but my brain can't hold, i am familiar with multi dimensional array but what are these ?

$options['data']=$row[0];

hello friends

what does this type of array means ?

$data[] = $row;

Hello
Is there any way to find out what is type of proxy? I mean Anonymous, Transparent etc.

Hi.

I want to create a list of files in a directory. But I don't want all the files to be listed, only .gif, .jpg and .bmp.

Does anyone know the PHP code how to do that? (My directory name is 'images' if you need that).

Thanks!

Hi

Not that often I play with these (and normally just a single font I use).

However I am trying to generate an image with a ttf bit of text on it. No problem using Tuffy.ttf (the normal one I use), but I want to use some arrow characters which it doesn't support.

I have tried using Wingding and Webdings but neither work with GD.

Am I missing something (hopefully something obvious)?

All the best

Keith
