[SOLVED] absolute path?

[182x]

hey guys,

 

I was reading a tutorial on PHP and it referes to absolute and relative paths I was just wondering is the following "../test/test2/test.php" classed as an absolute or relative path?

The reason I ask is that I always thought it was a relative path but in the tutorial for jpgraph it states that only absolute paths can be used and the above style works.

 

thanks.

From what I understand thats a relative path, an absolute path would have the address in like http://www.yourhostname.com/path1/path2/path3.php.

 

Relative path would be like /path1/path2/path3.php.

 

Someone correct me if Im wrong though

Relative paths are paths relative to the file location:

 

<?php include './lib/mysql.class'; ?>

If the file is in /var/www then this becomes /var/www/lib/mysql.class

If the file moves to /etc/website then this becomes /etc/website/lib/mysql.class

 

Absolute paths are relative to the directory structure, and aren't affected by when the file moves:

 

<?php include '/home/steve/bot/lib/mysql.class'; ?>

No matter where the file is located this path is always /home/steve/bot/lib/mysql.class.

Could this then lead to any problems that I have used a relative path? Although in testing it seems fine.

There shouldn't be any problems as long as you keep the paths correct.

 

IE: If you move index.php you have to move the file you're pointing to also.

Thanks, am I correct in assuming that the ".." in the path means go back back one directory? So if "../../" was used it means go back two directories?

[Crow]

Exactly (just as . is current directory)
