File_Find / manual examples

Looking at the PEAR manual I can see examples using static calls. However when trying to use a static call like this: $file = File_Find::maptree('/tmp/'); File_Find dies with: Warning: Problem with method call - please report this bug in /usr/local/lib/php/File/Find.php on line 112 Warning: First argument to array_push() needs to be an array in /usr/local/lib/php/File/Find.php on line 197 Warning: First argument to array_push() needs to be an array in /usr/local/lib/php/File/Find.php on line 113 I can see the problem is array_push($this->files, $entry); in the line 197. When using static call $this->files does not get initialized as an array causing the error. However if I use File_Find as an object: $f = new File_Find(); $file = $f->maptree('/tmp/'); things work fine. Is there a reason why the examples in manual use static calls (this is the case with many other manual entries too)? -- Mika Tuupola http://www.appelsiini.net/~tuupola/
