note 52376 added to function.implode

It's always dangerous to give sweeping statements like "this will always work!". Your solution is much more elegant than mine, but perhaps it's a little too elegant for its own good! Try giving it an array with zero or one elements in it for example. You could say that folks shouldn't call it in that case, but you know folks... they like pushing the boundaries. :-) Perhaps you meant to say that the array can be altered inside the function because it is passed "by value" rather than "by reference", or is that just a mixture of terminology from my C++ upbringing? Passing by reference would imply that you could alter the array inside the function and have that alter its value outside. Passing by value implies that any changes inside the function affect the local function copy only. In PHP, the latter is clearly the case, unless a variable is explicitly declared as global. OK, that's my 2c. ---- Manual Page -- http://www.php.net/manual/en/function.implode.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+52376 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+52376&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+52376&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+52376&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+52376&report=yes&reason=useless Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+52376&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+52376&report=yes Search -- http://master.php.net/manage/user-notes.php
