Try this one

DIRECTORY_SEPARATOR

    $patch = $somePath. DIRECTORY_SEPARATOR .$someFile

or you can define yours 

    PHP_OS == &quot;Windows&quot; ||
        PHP_OS == &quot;WINNT&quot; ? define(&quot;SEPARATOR&quot;, &quot;\\&quot;) : define(&quot;SEPARATOR&quot;, &quot;/&quot;); 

    if (strtoupper(substr(PHP_OS, 0, 3)) === &#39;WIN&#39;)           
        define(&quot;SEPARATOR&quot;, &quot;\\&quot;);
    else 
        define(&quot;SEPARATOR&quot;, &quot;/&quot;);

I want to strip script tags out of this HTML at Pastebin:

&gt; http://pastebin.com/mdxygM0a  

I tried using the below regular expression:

    html.replace(/&lt;script.*&gt;.*&lt;\/script&gt;/ims, &quot; &quot;)

But it does not remove all of the script tags in the HTML. It only removes in-line scripts. I&#39;m looking for some regex that can remove all of the script tags (in-line and multi-line). It would be highly appreciated if a test is carried out on my sample http://pastebin.com/mdxygM0a

I hear that `GL_QUADS` are going to be removed in the OpenGL versions &gt; 3.0, why is that? Will my old programs not work in the future then? I have benchmarked, and `GL_TRIANGLES` or `GL_QUADS` have no difference in render speed (might even be that `GL_QUADS` is faster). So whats the point?

What is so bad about GL_QUADS?

I&#39;m building a path string in PHP. I need it to work across platforms (i.e., Linux, Windows, OS X). 
I&#39;m doing this:

    $path = $someDirectory.&#39;/&#39;.$someFile;

Assume `$someDirectory` and `$someFile` are formatted correctly at run-time on the various platforms. This works beautifully on Linux and OS X, but not on Windows. The issue is the `/` character, which I thought would work for Windows.

Is there a PHP function or some other trick to switch this to `\` at runtime on Windows?

&lt;b&gt;EDIT:&lt;/b&gt; Just to be clear, the resultant string is 

    c:\Program Files (x86)\Sitefusion\Sitefusion.org\Defaults\pref/user.preferences

on Windows. Obviously the mix of slashes confuses Windows.

I am uploading a file in php and only want to upload it if it&#39;s a csv file. I believe my syntax is right for the content type. It always goes to else statement when it&#39;s a csv file. What I am doing wrong here?

    if (($_FILES[&quot;file&quot;][&quot;type&quot;] == &quot;text/csv&quot;))
    {
    
    }
    else
    {
    
    }

If I change the content type it works for that format just not csv.

I&#39;m writing a RESTful API module for an application in PHP, and I&#39;m a bit mixed on the verbs `HEAD` and `OPTIONS`.

&gt; - `OPTIONS&#160;` Used to retrieve the available HTTP verbs for a given resource?
&gt; - `HEAD`     Used to determine whether a given resource is available?

If someone could clarify* these verbs, that would be much appreciated.

&lt;sub&gt;* The clarification was with respect to RESTful API architectures re-purposing HTTP verbs. I&#39;ve since come to the realization that both `HEAD` and `OPTIONS` should *not* be re-purposed, and instead behave predictably as any HTTP application should. Oh, how we grow in 2 years.&lt;/sub&gt;

RESTful API methods; HEAD &amp; OPTIONS

I have an array where I want to search the `uid` and get the key of the array.

## Examples
Assume we have the following 2-dimensional array:

    $userdb = array(
        array(
            &#39;uid&#39; =&gt; &#39;100&#39;,
            &#39;name&#39; =&gt; &#39;Sandra Shush&#39;,
            &#39;pic_square&#39; =&gt; &#39;urlof100&#39;
        ),
        array(
            &#39;uid&#39; =&gt; &#39;5465&#39;,
            &#39;name&#39; =&gt; &#39;Stefanie Mcmohn&#39;,
            &#39;pic_square&#39; =&gt; &#39;urlof100&#39;
        ),
        array(
            &#39;uid&#39; =&gt; &#39;40489&#39;,
            &#39;name&#39; =&gt; &#39;Michael&#39;,
            &#39;pic_square&#39; =&gt; &#39;urlof40489&#39;
        )
    );

The function call `search_by_uid(100)` (uid of first user) should return `0`.

The function call `search_by_uid(40489)` should return `2`.

I tried making loops, but I want a faster executing code.


PHP multidimensional array search by value

I am working on a page that requires javascript and sessions. I already have code to warn the user if javascript is disabled. Now, I want to handle the case where cookies are disabled, as the session id is stored in cookies.

I have thought of just a couple ideas:

 1. Embedding the session id in the links and forms
 2. Warn the user they must enable cookies if they are disabled (would need help detecting if cookies are disabled)

What is the best way to approach this? Thanks

**EDIT**

Based on the articles linked, I came up with my own approach and thought I would share, somebody else might be able to use it, maybe I will get a few critiques. (Assumes your PHP session stores in a cookie named `PHPSESSID`)

    &lt;div id=&quot;form&quot; style=&quot;display:none&quot;&gt;Content goes here&lt;/div&gt;
    &lt;noscript&gt;Sorry, but Javascript is required&lt;/noscript&gt;
    &lt;script type=&quot;text/javascript&quot;&gt;&lt;!--
    if(document.cookie.indexOf(&#39;PHPSESSID&#39;)!=-1)
       document.getElementById(&#39;form&#39;).style.display=&#39;&#39;;
    else
       document.write(&#39;&lt;p&gt;Sorry, but cookies must be enabled&lt;/p&gt;&#39;);
    --&gt;&lt;/script&gt;

Check if cookies are enabled

I&#39;m trying to get hold of the largest value in an array, while still preserving the item labels. I know I can do this by running sort(), but if I do so I simply lose the labels - which makes it pointless for what I need. Here&#39;s the array:

    array(&quot;a&quot;=&gt;1,&quot;b&quot;=&gt;2,&quot;c&quot;=&gt;4,&quot;d&quot;=&gt;5);

Any ideas?

I&#39;ve got a conditional to check if a certain file exists before proceeding (`./logs/error.log`). If it isn&#39;t found I want to create it. However, will

    File tmp = new File(&quot;logs/error.log&quot;);
    tmp.createNewFile();

also create `logs/` if it doesn&#39;t exist?


Java&#39;s createNewFile() - will it also create directories?

I&#39;ve just downloaded a 4.5GB depot to a location on my hard drive that is not ideal.

I&#39;d like to move the folder that Perforce now sees as the &quot;workspace&quot; folder (iPhone) to another folder on my hard disk (Project Name), and then use *that* folder as the workspace folder.

Is this possible, or do I need to download the entire depot again?

Thanks,
Dave

I run R on Windows, and have a csv file on the Desktop. I load it as follows,

    x&lt;-read.csv(&quot;C:\Users\surfcat\Desktop\2006_dissimilarity.csv&quot;,header=TRUE)


but the R gives the following error message

&gt; Error: &#39;\U&#39; used without hex digits in character string starting &quot;C:\U&quot;

What does the following file path mean? 

    $(Services_Jobs_Drop_Path)\**\*.config

The variable just holds some path, nothing interesting. I&#39;m a lot more concerned, what the hell the `**` mean.
Any ideas?

P.S. The following path is used in msbuild scripts, if it helps.

What does two asterisks together in file path mean?

I have a path (including directory and file name).  
I need to test if the file-name is a valid, e.g. if the file-system will allow me to create a file with such a name.  
The file-name *has some unicode characters* in it.

It&#39;s safe to assume the directory segment of the path is valid and accessible (&lt;sup&gt;I was trying to make the question more gnerally applicable, and apparently I wen too far&lt;/sup&gt;).

I very much do not want to have to escape anything unless I *have* to. 

I&#39;d post some of the example characters I am dealing with, but apparently they get automatically removed by the stack-exchange system. Anyways, I want to keep standard unicode entities like `&#246;`, and only escape things which are invalid in a filename.

---

Here is the catch. **There may (or may not) already be a file at the target of the path.** I need to keep that file if it does exist, and not create a file if it does not.

Basically I want to check if I *could* write to a path **without actually opening the path for writing** (and the automatic file creation/file clobbering that typically entails).

As such:

    try:
        open(filename, &#39;w&#39;)
    except OSError:
        # handle error here
[from here](https://stackoverflow.com/questions/4102896/check-whether-a-path-is-valid-in-python)

Is not acceptable, because it will overwrite the existent file, which I do not want to touch (if it&#39;s there), or create said file if it&#39;s not.

I know I can do:

    if not os.access(filePath, os.W_OK):
        try:
            open(filePath, &#39;w&#39;).close()
            os.unlink(filePath)
        except OSError:
            # handle error here

But that will *create* the file at the `filePath`, which I would then have to `os.unlink`.

In the end, it seems like it&#39;s spending 6 or 7 lines to do something that should be as simple as `os.isvalidpath(filePath)` or similar.

---

As an aside, I need this to run on (at least) Windows and MacOS, so I&#39;d like to avoid platform-specific stuff.

    C:\stuff\directory_i_need\subdir\file.jpg

I would like to extract `directory_i_need`.

So I have a web project, and I&#39;m trying to get the root directory of the website using the c# method `Directory.GetCurrentDirectory()`.  I don&#39;t want to be using a static path as the file locations will be changing in the future.  This method is running in my imageProcess.aspx.cs file, but where I thought it would return:

    C:\Users\tcbl\documents\visual studio 2010\Projects\ModelMonitoring\ModelMonitoring\imageProcess.aspx.cs

I&#39;m instead getting:
    
    C:\Program Files\Common Files\Microsoft Shared\DevServer\10.0\

Can anyone explain why this is happening and what a possible solution might be? Thanks a lot.
