RE: [PHP] Require() vs Include()

As I already tried to mention in here: Now (since the PHP4.0.2) require() and include() are working in the EXACTLY same way. the only difference remains the premature exit of the file on a failure of require(). It is what Zeev wrote in his previous email on my thread.

One would always be included where as the other would only be included if it meet the condition it was in.

Is my paraphrasing correct? require() is "absolute" -- so don't use it in a conditional statement because it makes no sense (to me anyway) require() is "absolute" -- make sure that what you "require" exists where it's suppose to be, otherwise the script fails "hard". include() is *not* absolute -- use it in a conditional include() failures do so "softly" - returns garbage, e.g. Up to php4.0.1 require() had the edge on speed -- none to very litle with php4.0.2+. -duke Calgary,Alberta, Canada -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: php-general-unsubscribe@lists.php.net For additional commands, e-mail: php-general-help@lists.php.net To contact the list administrators, e-mail: php-list-admin@lists.php.net -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: php-general-unsubscribe@lists.php.net For additional commands, e-mail: php-general-help@lists.php.net To contact the list administrators, e-mail: php-list-admin@lists.php.net
