Getting an absolute path

[Xu Wei Jie]

Hi all,

 

I wish to retrieve absolute path. However, I am not getting the results I need using realpath nor dirname (i.e ./a.php)

 

realpath will return me empty string and dirname will return me '.'

 

you guys have any ideas how php can resolve absolute address using a relative path and a file name?

[Mchl]

realpath($_SERVER['PHP_SELF']);

Or...

dirname(__FILE__);

but if I want to parse in ./a.php as a string? is there anyway php can tell me its absolute path?

[ratcateme]

realpath("./a.php");

 

Scott.

Scott, thanks.

 

I realized that the file parsed in needs to be an existing file and the integral path should be valid else realpath won't return its absolute path. Previously, I was passing in a file and expecting that it would get its absolute path by finding where the file resides.

Perhaps you could do

$file = './a.php'

if(file_exists($file))
{
     $file_path = realpath($file);
}
