I can't believe PHP doesn't have an easy solution for this simple matter. ASP.NET has a ~ sign that takes care of this issue and starts everything from the root level. Here's my problem:
localhost/MySite
-->Admin
-- Edit.php
-->Class
-- class.EditInfo.php
-->Texts
-- MyInfo.txt
--ShowInfo.php
Inside class.EditInfo.php I am accessing MyInfo.txt so I defined a relative path "../Texts/MyInfo.txt". Then I created an object of EditInfo in Admin/Edit.php and accessed Texts/MyInfo.txt - it worked fine.
But now I have to create an object of EditInfo in ShowInfo.php and access Texts/MyInfo.txt and here's the problem that occurs. As I am using a relative path in my class, whenever I am creating an objEditInfo and trying to access MyInfo.txt I am getting "File doesn't exist" error.
Now I am looking for something that's equivalent to "~/Texts/MyInfo.txt" from ASP.NET. Is there anything similar to that out there??? Or do I have to set the path with some if/else condition?
UPDATE:
I used $_SERVER['DOCUMENT_ROOT']. I was using a subfolder where my actual website was. So I had to use $_SERVER['DOCUMENT_ROOT']."/mySite" & then adding rest of the address ("/Texts/MyInfo.php") to it.
Create a constant with absolute path to the root by using define
in ShowInfo.php
:
define('ROOTPATH', __DIR__);
Or PHP <= 5.3
define('ROOTPATH', dirname(__FILE__));
Now use it:
if (file_exists(ROOTPATH.'/Texts/MyInfo.txt')) {
// ...
}
Or use the DOCUMENT_ROOT
defined in $_SERVER
:
if (file_exists($_SERVER['DOCUMENT_ROOT'].'/Texts/MyInfo.txt')) {
// ...
}
