The dirname function is present in both PHP 4 and 5 and does not rely on any external libraries. Are you sure you're spelling it right? http://php.net/dirname > I must be really dense... > What I don't understand in the above is this - dirname refers to what > directory? -- the directory of the file that is including? what if the > directory is the root directory of the site? > > (_FILE_) = what? - (_filename.ext_) or (filename.ext) --- what file is > this, the file which is including the file header.php? The __FILE__ (note 2 _'s either side) constant is the full path and filename to the current script. The dirname function knocks the filename off it to give you the directory the current script is in. You can then append a / and then the relative path to the script you want to include. By doing this you're ensuring that all includes are relative to the current script and are not affected by ini settings or anything else. > and what does the . mean and then "/../header.php" --- I don't > understand what to enter here The . is the string append operator. I tend to assume the most basic level of PHP knowledge from users of this list and I include the string append operator in that set. You might want to find a beginners tutorial for PHP and work through that to give you a solid foundation before attempting to work with multiple scripts. -Stuart -- http://stut.net/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
