I am studying pantelid alorithm and I need help regarding regular expression of alorithm pantolides located inside it index.php of main package @ http://jpye.dyndns.org/pantelides/
in the index.php file, I see:
if(preg_match_all("#\\b([az][a-z_0-9]*)(?!\\()\\b#i",$str,$matches)){
Now, I am not an expert in reg exp, but I know what [az] means, but does that \\b
mean?
