Well, I didn't have output mangling in mind when I wrote the output buffering, but after it was done, it seemed like a crime not to allow some added value there. I'll show you the API and you can decide for yourself (all functions begin with ob_, which stands for output buffering): ob_start() /* begin buffering output */ ob_end_flush() /* flush the output buffer, and end output buffering */ ob_end_clean() /* discard the output buffer, and end output buffering */ ob_get_contents() /* return the contents of the output buffer */ For example, a very simple script: <? ob_start(); print "Hello, world!"; $output = ob_get_contents(); ob_end_clean(); print $output; ?> is just a very impressive and inefficient way to do: <? print "Hello, world!"; ?> Zeev -- ----------------------------------------------------- Zeev Suraski <zeev@zend.com> For a PGP public key, finger bourbon@netvision.net.il -- PHP Development Mailing List http://www.php.net/ To unsubscribe send an empty message to php-dev-unsubscribe@lists.php.net For help: php-dev-help@lists.php.net
