Going to 'Explode'!!

[alant]

Still trying to get my head around php.
[code]<?php
function path()
{$a=($_SERVER['SCRIPT_NAME']);
$b=explode("/",$a,-1);
print "C:\\text";
foreach ($b as $c) { print ($c . "\\"); }}
$p=path();
echo $p;
?>
[/code]

I have made my website to call .txt files which are stored in a different root dir from my website but in an identical folder structure. e.g my index php is in 'C:\www\resources\index.php' and the text file is in "C:\text\resources\filename.txt".
The code above succesfully returns on screen the string: "C:\text\resources\"
I then want to use that string with the include function  e.g: [code]<?php include($p . "filename.txt")?>[/code]
However the include code doesn't seem to work with variables. Anyone have any ideas?

You might want to get into the habbit of formatting your code so its readable. Then, you need the function to [i]return[/i] the value, not just simply print it. eg;

[code]
<?php
function path() {
  $a = $_SERVER['SCRIPT_NAME'];
  $b = explode("/",$a,-1);
  $c = "C:\\text";
  foreach ($b as $c) {
    $c .= "\\";
  }
  return $c;
}
$p = path();
include $p . "filename.txt";
?>
[/code]

Ok thanks for that. It is partially working with that code. However if i use a folder more than one level deep then return $c only returns the last folder in the array. How can I get it to return multiple values? e.g if i have another php file inside [i]C:\resources\folder1[/i] the code only returns the value of [i]C:\text\folder1\[/i] rather than the full path of [i]C:\text\resources\folder1\[/i].
Also is there any php equivalent of the DOS command: 'CD\'?

Thanks,

Really there are much better ways of going about what it seems you are trying to do. Take a look at the $_SERVER['DOCUMENT_ROOT'] variable and work from there.

And no, DOS is an operating system, php is not and has no use for a [i]command[/i] cd.

Thanks, $_SERVER['DOCUMENT_ROOT'] was the sort of thing I was meaning. However now I have another problem it doesn't appear to have a value. phpinfo says there is no value for doc_root and using: echo  $_SERVER['DOCUMENT_ROOT'] returns nothing.

Thats unusuall. This would be a server configuration issue, what server and OS are you using?

[alant]

Using IIS6 on Windows 2003 Server. With PHP 5.2 ISAPI installed.
It's also configured to host multiple websites. I just attempted to do another echo on one of the other websites and it returned 'C:\www'. However looking through the config for each website they don't appear to be set any differently.  ???

Sorry, Ive never worked with php in IIS or Windows. The php manual states that the $_SERVER['DOCUMENT_ROOT'] variable is....

[quote]The document root directory under which the current script is executing, as defined in the server's configuration file.[/quote]

Sorry, but I can't help you.
