PHP - Php Image Type Refference

Weird question.

I am using a captcha class which creates the code/image simply by doing this:
Code: [Select]
<img src="captcha.php">

The captcha.php file has lots of code of course, but this being key to my question:
Code: [Select]
header("Content-Type: image/jpeg");
ImageJpeg($image);

Can I do it so I can create the image in the PHP of the actual script executing, so I don't have to call captcha.php in the image?
- So it would look like this: (well no, but I think this explains what I want)
Code: [Select]
<img src="<?php echo $captchaCreated; ?>">

I am using a MVC design and don't see why the captcha should try and change this.

Probably a stupid question . . .   The MIME type in my php.ini file is set to text/html:

default_mimetype = "text/html"

But, because I use XHTML 1.0 Strict, the MIME type of my web pages is set to text/xml:

<meta http-equiv="content-type" content="text/xml; charset=utf-8" />

I should therefore change the php.ini MIME type to text/xml, right?

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;
}

Hello,

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

Broadband etc.

I have a question regarding how I can make a debate type box that includes a comment section where you can explain your side, as well as a radio button to choose Pro or Con, and a place for name or email. When submit I want the Pro to be on left side and Con on the right.

The best way I can describe it is by showing you a website I found which has what I want.    http://www.squidoo.com/xbox-vs-playstation

I hope I dont get called out as a newb, I have recently begun learning web design including html, css, js, php, and more but am still learning! If I should be posting in html, css, js, or elsewhere please let me know.

I would just like to know what it takes to build this. From the form itself, to the submit file that separates them to a designated side based on the radio box choice, as well as anything else that I am not thinking of.

I will most likely be using this form on my Wordpress Powered website if that changes anything (where the comments get saved to?)

If you took the time to read this I appreciate your time and any thoughts or suggestions you may have.
Ciao

I have a Form and need to loop through 10 fields on it.

Which Looping Structure would be best and why?

In PHP, I believe my choices are...

- For Each
- Do While
- While

Thanks,

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.

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??

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?

$_GET['id'] = (empty($_GET['id'])) ? 0 : $_GET['id'];

I'm going over someones code, the site is super flawed, Ive got to much going on at once and I can't wrap my head around that. Is it if the string is empty or 0 then use the get variable or is it something else?
