xattr_get - Get an extended attribute

SYNOPSIS
       string xattr_get (string  $filename, string  $name, [int  $flags])

DESCRIPTION
	This function gets the value of an extended attribute of a file.

       Extended attributes have two different namespaces: user and root. The user namespace is available to all users, while the root namespace is
       available only to users with root privileges. xattr operates on the user namespace by default, but this can  be	changed  with  the  $flags
       parameter.

	      o $filename
		- The file from which we get the attribute.

	      o $name
		- The name of the attribute.

	      o $flags
		-

	      Supported xattr flags
