note 56819 added to function.set-include-path

Darn. All of that and I missed two things: 1) array_unique(array_merge()) might have been smarter than array_flip(array_flip(array_merge())); I did not know that array_unique() existed. According to a note on the array_unique() page, though, flip-flip is usually much faster and less memory intensive. 2) the comments about the array_flip() stuff should read: // flipping once makes the paths into the keys, // duplicate keys are eliminated automatically // array( 1=>'/path1', 2=>'/path2', 3=>'/path2', 4=>'/path3' ) // becomes array('/path1'=>1, '/path2'=>3, '/path3'=>4 ) // flipping again returns the array back // into array( 1=>'/path1', 3=>'/path2', 4=>'/path3' ) Neither of the above directly affect the functionality, but if you are trying to learn array_flip(), I did not want to lead you astray. ---- Manual Page -- http://www.php.net/manual/en/function.set-include-path.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+56819 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+56819&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+56819&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+56819&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+56819&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+56819&report=yes&reason=non-english Delete: already in docs -- http://master.php.net/manage/user-notes.php?action=delete+56819&report=yes&reason=already+in+docs Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+56819&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+56819&report=yes Search -- http://master.php.net/manage/user-notes.php
