Re: Array vs. Scalar Lists

I don this all the time: print implode ( '', $arrayOfStrings ) ; However, $arrayOfStrings must be a one dimentional array. you could also loop through it. while (list($key, $val) = each($arrayOfStrings)) print $val; -jeremy brand Jeremy Brand :: Sr. Software Engineer :: 408-245-9058 :: jeremy@nirvani.net http://www.JeremyBrand.com/Jeremy/Brand/Jeremy_Brand.html for more - - Begin - Advertisement - - - - - - - - - - - - - - - THIS SPACE FOR SALE - - - NO JOKE Get your own Free, Private email at http://www.smackdown.com/ - - - - - - - - - - - - - End - Advertisement - - - - - On Fri, 1 Dec 2000, Anthony Martin wrote: > Date: Fri, 1 Dec 2000 12:12:01 -0800 > From: Anthony Martin <Anthony@TRAMS.com> > To: "'php-general@lists.php.net'" <php-general@lists.php.net> > Subject: [PHP] Array vs. Scalar Lists > > I was wondering if there's a way to pass array keys implicitly to a function > that expects a list of scalars. > > I'm used to perl's method of handling arrays as lists of scalars.
