Using shell commands is probably the most asinine way of string manipulation in PHP. For Pete's and portability's sake, use native functions:
$str = preg_replace("/[^a-z0-9-]/", "-", strtolower($str));
I'm going to have to agree with anonymous here...
unless the shell command runs somewhere around 200x faster than preg_replace then it might be useful in certain situations.
I Agreeeee!
Use Anonymous' code
$str = preg_replace("/[^a-z0-9-]/", "-", strtolower($str));
$str = preg_replace( "/[^\w_-]/", "-", strtolower( $str ) );
aren't we forgetting dots in file names? and "\w" already includes "_".
$str = preg_replace("/[^\w\.-]/", "-", strtolower($str));
It was really a nice article and I was really impressed by reading this Ruby on Rails Online Training India
