note 51778 added to language.variables

Note that with php you can also use double variables. I don't believe this was stated yet. Here is how you would go about doing so. They are handy for OOP (Object Oriented Programming) and make it easier to recall what the variables are used for and what their contents are. <?php # declaring double and single variables $my_variable = 'PHP is neat'; $$my_variable = ' and handy!'; echo $my_variable . $$my_variable; # this would return 'PHP is neat and handy!' ?> The use of double variables becomes more adament when you begin creating large projects. Say for instance someone has a variabled named $message_title for an online webmail system. Well, they could have the variable $$message_title which could be formatted in some way and they only want to return the formatted string. ---- Manual Page -- http://www.php.net/manual/en/language.variables.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+51778 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+51778&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+51778&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+51778&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+51778&report=yes&reason=useless Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+51778&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+51778&report=yes Search -- http://master.php.net/manage/user-notes.php
