<p>To not have to touch the old stuff I think to somehow "kin of remotely" invoke the new one, need only to pass the $_REQUEST[] data. I can not include it as that would require migrating to another PHP version (and some name clashing). I don't need any output from the new one.</p>

<p>as you can see, if the function get LIMIT or 0,5 it will be removed, how i can remove any type of word like "number, number" so the query will be LIMIT 10, 40 it will be removed too.<br>
to know if a string is with format of "is_number,is_number".

<p>In my real code, I need to construct an object and test it, while also having it destroyed when the if-block ends. Basically, I'm looking for something like this:</p>
<pre><code>{

// ...
}
}

<p>Of course, this would work:</p>
<pre><code>if (Dingus dingus = another_dingus) { /* */ }
</code></pre>
<p>But then I'm constructing a <code>Dingus</code> and calling <code>operator=</code> on it. It seems logical to me that I would be able to construct the object using whatever constructor I please.</p>
<p>But I'm baffled why this isn't grammatically correct. I've tested with G++ and MSVC++ and they both complain about this construct, so I'm sure it's part of the spec but I'm curious as to the reasoning for this and what non-ugly workarounds there may be.</p>

The selected image is saved as a file and then uploaded.</p>
<p>Now, however, I wish to save it as a 'Image' so I can resize it etc. So that the code would be:</p>
<pre><code> if (openFileDialog1.ShowDialog() == DialogResult.OK)

image = Image.FromFile(openFileDialog1.FileName);

<p>Now my selected file is a Image file. How do I convert it into the filestream? If this can't be done easily then how would I upload the image via ftp?

<p>I found this: [http://www.uzbl.org/wiki/uzbl_tabbed][2] which I couldn't understand. It says there's a .py that communicates to the configuration file which I don't quite understand. I don't know anything about python and I can't find the configuration file. Plus, I just thought I could use a simple keyboard shortcut while using the browser anyway.</p>

<p>What is the best way to import javascript file (file.js) in javascript function().</p>
<p>For example what is the best way to replace the todo statement:</p>
<pre><code>function doSomething() {
if (xy.doSomething == undefined) {
// todo: load 'oldVersionPatch.js'
}
...
}
</code></pre>
<p>Possibly the best solution is to create script element and add it into html page.
My questions are:</p>
<ul>
<li>is it better to add/append it into head, or body (what will load when)?</li>
<li>is it better to use javascript or jquery (what is more cross-browser compatible)?</li>
</ul>

3,401,330 | 3,401,331 | IE6 caching cookie values when back button is used | <p>Our user authentication system makes use of cookies and $_SESSION variables to determine logged-in status. Every page tests for the presence of a user_id $_SESSION variable and a user_auth cookie:</p>
<pre><code>if(!isset($_SESSION['user_id']) || !isset($_COOKIE['user_auth'])){
// send user through login
}
</code></pre>
<p>and sends the user through the login process if they're not found.The logout button loads the following page:</p>
<pre><code><?php
session_start();
setcookie('user_auth','',time()-360000,'/','domain.com');
session_unset();
session_destroy();
header("location: http://home.domain.com");
?>
</code></pre>
<p>In Firefox, logging out and then pressing the back button sends the user back through the login process. However, in IE6 these values are retained and the user is able to access the page again. The values are definitely being destroyed as reloading the page sends the user back through the login process, but I'd obviously prefer IE6 to send the user straight back to login as Firefox does. I have tried using no-cache and revalidate headers, to no avail. </p>
<p>(Before it's suggested, using Firefox/Safari/Chrome/IE8 is not an available option.)</p>

5,556,630 | 5,556,631 | PHP DOMDocument stripping HTML tags | <p>I'm working on a small templating engine, and I'm using DOMDocument to parse the pages. My test page so far looks like this:</p>

<p>Main column of <span>content</span></p>

{
var savedVal = "";
return function (newVal)

if (typeof (newVal) === "undefined")

return savedVal;
}
savedVal = newVal;
};
})();

function Inherits(params) {
this.viewModel.title(params.title);

///// testing code:

<p>The application I'm trying to build is built completely from an API.

<p>I'd basically like a direction on what would be the best way to handle this kind of idea, I got told something called "polling" would work but I've never heard of it. Initially the idea is as provided below</p>
<ol>
<li>Load set page "bid.php"</li>
<li>Enter certain criteria</li>
<li>Click submit as to which an "Ajax" request of some sort would start</li>
<li>The recurring cURL request would be activated through the Ajax.</li>
<li>Display the data back from the cURL request every 3 seconds via Javascript.</li>
</ol>
<p>I'm not initially asking for the work to be given to me, I'm just asking the professionals as to which they recon would be the best way I can do this task.</p>
