Calling $_SERVER['SCRIPT_NAME'] from files deeper in the hierarchy

Hopefully this will come close (all this should be in variables.php):

// folder containing the requested script $requested = dirname($_SERVER['SCRIPT_FILENAME']); // folder containing variables.php $current = dirname(__FILE__); // relative path from variables.php to the requested script $relative = str_replace($current, '', $requested); // remove relative path from end of script name $pattern = '#' . preg_quote($relative) . '$#'; $basePath = preg_replace($pattern, '', dirname($_SERVER['SCRIPT_NAME'])); 

Note: This looks like it will work for your particular example, but this means that variables.php must always be in a folder either at, or a parent of, the DOCUMENT_ROOT, otherwise the relative path can't be determined using the above.

I'm not sure it's gonna solve your problem forever or not, however it works in your example:

$x = explode("/", $_SERVER['SCRIPT_NAME']); echo $_SERVER['SERVER_NAME'] . '/' . $x[1] . '/'; 

If you like the output, you may customize it to fit your needs. :)

It's not entirely foolproof, but the solution used by Kurogo works in most cases.

https://github.com/modolabs/Kurogo-Mobile-Web/blob/release-1.5/lib/Kurogo.php#L797

It's basically comparing the REQUEST_URI and the DOCUMENT_ROOT, and keeps adding folders from the REQUEST_URI to the DOCUMENT_ROOT until it gets a match. Once it finds WEBROOT_DIR (which in your case would probably be a dirname(__FILE__) from the variables.php) by building up from DOCUMENT_ROOT, it saves the existing path as your $urlBase.

This only works for subfolders/symlinks, and doesn't handle things like apache aliasing, so it may not work for your case specifically, but it's at least part of the answer.

I worked in a project where it was necesary to read a directory with a lot of images, with folders within, and it was required to read all the files in a recursive way...

Function:

function ListIn($dir, $prefix = '') { $dir = rtrim($dir, '\\/'); $result = array(); foreach (scandir($dir) as $f) { if ($f !== '.' and $f !== '..') { if (is_dir("$dir/$f")) { $result = array_merge($result, ListIn("$dir/$f", "$prefix$f/")); } else { $ext = substr($prefix.$f, strrpos($prefix.$f, '.') + 1); if(in_array($ext, array("jpg"))){ // echo $prefix.$f."<br>"; $result[] = $prefix.$f; } } } } return $result; } 

Way of use:

$path='images/mytest'; $images = (ListIn($path)); foreach($images as $image){ $image=explode("/",$image); echo $image=$image[2]; } 

As you can see, every single image becomes an array, and you can access to the first elements of that array, in order to extract the directory you want... In this case it was located at the second index of the array, depending on the deepness of your file structure...

I hope this can help you out!

I obviously do not want to hardcode this path in. The reason is that when I upload it onto a production server, the location changes to something more sane like http://example.com/ (and I don't want to have to modify this hardcoded path after uploading to the server, hence this question of course).

You can hardcode paths, just make it relative to the homepage.

For example, http://localhost/~noob/test-website/ and http://example.com are the same thing. so only worry about things underneath that .

(Preliminary note: There are seemingly many variants of this question already here, but they all seem to focus on the filesystem location of the physical PHP files themselves, not the web URL location of things, which is what I'm after.)

[HR][/HR]INTRO 1:

I have a small "website" with the following physical filesystem structure:

variable.phpfolder test.php(In other words, variable.php in the top-level, and test.php in the folder folder.) Here are the file contents:

[HR][/HR]INTRO 2:

When developing this "website" locally, it is on this address:

http://localhost/~noob/test-website[HR][/HR]QUESTION:

The problem is that if I put

localhost/~noob/test-website/folder/test.php into my browser, it prints out /~noob/test-website/folder/.

I want it to print out /~noob/test-website (the "web location" of variable.php). In other words, I want to have global access from all files, even ones deeper in the filesystem hierarchy, to /~noob/test-website. How do I accomplish this?

You can estimate the correct answer based on your knowledge of your specific folder and web structure, but that is far from a general solution. But I would recommend you to use a boostrap file that is the entry point for each "page". There you can setup you $basePath variable and other needed values.

Another thing you could do is inject the base path to your $_SERVER array from Apache (if that is what you are using. It would then be available to your entire application.

For a pointer on how to accomplish this you can look here.

Or have a config file containing the base path for a given server.

I think, you're searching the docroot (form outside) - it can be found in $_SERVER['DOCUMENT_ROOT'] (in the filesystem) & compare with __DIR__ (or dirname(__FILE__) for earlier PHP)

Use this function :-

#This function will return the current script name function get_script_name() { $uri_array = explode('/',$_SERVER['SCRIPT_NAME']); $script_name = end($uri_array); return $script_name; } #call The function $script_name = get_script_name(); echo $script_name;
