xattr_remove - Remove an extended attribute

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

DESCRIPTION
	This function removes 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.

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

	      o $name
		- The name of the attribute to remove.

	      o $flags
		-

	      Supported xattr flags
