Absolute path

[waynew]

Ok, I've never needed to use this until now. :\ And Google seems to give me everything but the right result:

 

How do I get the absolute path to something. I need this because I'll be reusing the same file in multiple directories and I reckon that changing every link to every file manually is going to leave me in a world of hurt.

Damn you and your uber Google skills.

Found an article. It suggests something different. http://roshanbh.com.np/2008/01/absolute-path-and-relative-path-file-inclusion-in-php.html

 

What do you reckon? Bearing in mind that I'm working on my local server at the moment.

Damn you and your uber manual searching skillz.

 

Corrected.

It ain't a skill unless it has a "z" at the end.

I think you guyz must be aware of absolute path and relative path in PHP. If you do not know anything about it then let me explain you about absolute path and relative path in the server with the example using include() function of PHP. You can see the example below, I’ve included the same files in PHP but the same file is included in two different manner. 

 

That bad grammar made my day.  And in applications, I always set up a bootstrapping file that I always include relatively.  It sets everything else up.  Example

<?php
$homedir = '/home1/phpspeak';
$appdir = "$homedir/public_html/assignments";
function __autoload($classname)
{
	$path = '/home1/phpspeak/public_html/assignments/classes/' . $classname . '.class.php';
	if (file_exists($path)) {

		require_once ($path);
	}
}

$mysqlu = "";
$mysqlp = ""
$mysqld = "";
$mysqlh = "";

$db = new mysqli($mysqlh, $mysqlu, $mysqlp, $mysqld);
if ($db->connect_error) {
    	printf("Connect failed: %s<br />\n", mysqli_connect_error());
    	exit();
}

require ("$homedir/smarty/Smarty.class.php");
$template = new Smarty();

//Set up directories
$template->template_dir = "$homedir/smarty/templates";
$template->compile_dir = "$homedir/smarty/templates_c";
$template->cache_dir = "$homedir/smarty/cache";
$template->config_dir = "$homedir/smarty/configs";

$notes = new Note;

$registry = new Registry;
$registry->db = $db;
$registry->template = $template;
$registry->notes = $notes;

 

The only reason I hardcoded $homedir is because I felt like putting Smarty in a directory outside of the webroot.  Otherwise I would have used realpath() to get $homedir.

Are you talking about a file system path or a URL (i.e. link). They are two different things.

 

To form an absolute file system path for an include/require, use -

 

require $_SERVER['DOCUMENT_ROOT'] . "/path_to_file/your_file.php";

Whoops. I have a master file that includes another file that includes a bunch of classes.

 

I used:

require(realpath("include_me/classes/classes.php")); 

 

Bearing in mind that I include this master file at the top of all my pages; here's the error:

 

Fatal error: require() [function.require]: Failed opening required '' (include_path='.;C:\php5\pear') in C:\Program Files\Apache Group\Apache2\htdocs\waynewhitty02\include_me\master\master.php on line 13

[waynew]

I tried using:

 

$root = $_SERVER['DOCUMENT_ROOT'];
require($root."include_me/classes/classes.php"); 

 

But I still get:

 

Warning: require(C:/Program Files/Apache Group/Apache2/htdocs/include_me/classes/classes.php) [function.require]: failed to open stream: No such file or directory in C:\Program Files\Apache Group\Apache2\htdocs\waynewhitty02\include_me\master\master.php on line 13

 

Bear in mind that master.php is held inside a folder called master, which is inside the include_me folder.

C:/Program Files/Apache Group/Apache2/htdocs/include_me/classes/classes.php

 

If that did not work, then either that path is wrong of the file name does not exist in that folder -

No such file or directory
