SYNTAX: 'if ($_SERVER['PHP_SELF']...) for directory vs. file?

sherry

Hello.

How do you say,

if ($_SERVER['PHP_SELF'] == '/everything in a particular directory NOT just a particular file')
{

}

Thanks in advance.

I think I need a little clarification here. Do you mean if the currently running script is one of the files in the specified directory?

sherry

Thanks for your reply.

In this routine, many files use the same functions. I've created a custom (sub) routine that will be called by files from the 'public' directory. The problem is, files from the 'admin' directory also uses the same functions. I just want to control the execution of the custom code within that function based upon which directory is calling it BUT without duplicating code just to change the name.

So, if I had something like,

if (dir != '...'), then...

if (dir == '...'), then skip...or something else...

Thanks again in advance.

OK, I think you could use getcwd(), something like:

if(basename(getcwd()) == 'admin')
{
  // do admin stuff
}

Thanks for your reply.

I like that, also, except in my case, it seems to only go to the 1st level. I need it to go farther, especially to the 2nd level.

I'll play around with it using the example on PHP's website e.g. $path var, except I don't want to have to add the file name.

If you have any suggestions, it's always welcome.

Thanks again.

This may not work (just guessing here), but what about a wildcard?

if(basename(getcwd()) == 'admin/*')
{
  // do admin stuff
}

There's no "wildcard" in PHP... though you could use [man]substr/man to just retrieve the first 6 characters and compare them to "admin/".

I'm confused, I've used things like '*.jpg' before to search for all jpg files in a directory. So if that's not a wildcard, what is it? 😕

bradgrafelman

That would be because the [man]glob/man function has the added functionality of DOS-like search characters -- has nothing to do with the way PHP actually interprets the string "*.jpg".

EPJS

Ok I didn't know that. Thanks for informing me 🙂

OK, assuming the main directories are each immediately under the web root directory:

/**
* string getMainDir()
* returns first-level directory below web root directory of current script
* if script is in web root directory, returns FALSE
*/
function getMainDir()
{
   $dir = array_shift(explode('/', trim($_SERVER['PHP_SELF'], '/')));
   if($dir == basename($_SERVER['PHP_SELF']))
   {
      $dir = FALSE;
   }
   return($dir);
}

// USAGE:
$mainDir = getMainDir();
if($mainDir == 'admin')
{
  // do admin stuff
}
elseif($mainDir == 'public')
{
  // do public stuff
}
else
{
  // do something else
}

This is good stuff!

I'm trying to absorb it...

Thanks.
