问题 I have a script on a server that had php version 4. Now it is changed to php5 and the script does not function any more.

Inside is the line 88: $this = new $db( $serv, $user, $pass, $dbName ); What does the error mean and how can I change it? 回答1: $this is a special "variable" that always refers to the object the current function is executing in. It only makes sense

问题 Can someone help me to setup php4 for using json? Thanks! 回答1: Haven't tried this myself but you can have a look over here...

问题 in PHP4 there is no public,private,etc. So I am wondering if there is some sort of work-around so that I can make a class's property private and only accessible via getter/setter Thanks!! 回答1: You could approach this with a distinct syntax that clearly discourages the usage of such properties. You could borrow the python syntax of starting the method name with an underscore to define it as private. This doesn't block anyone from using it, of course, but its usage will be discouraged. 回答2: You

问题 I would like to separate my source folders into two: The folders that contain the code that you type into the address bar and those that make up parts of the page (tiles) and other code (classes, etc). So at the start of every php file I added: <?php // index.php include("config.php"); include("session.php"); ?> Config contains just this so far, but allows me to expand if I need other directories (logs, etc.) <?php // config.php $_PATHS["base"] = dirname(dirname(__FILE__)) . "\\"; $_PATHS[

问题 I have user defined function sort which sorts by date. It works fine for the same year and does not work when the year changes.

问题 I am using apc.php to check the PHP APC's stats (http://svn.php.net/viewvc/pecl/apc/trunk/apc.php) I have the following stats on a fairly busy server Cached Files 317 ( 26.3 MBytes) Hits 51483 Misses 6814 The problem is the Misses is always increasing (given a limited number of files), are there any way to check which files are missed?

问题 I know that PHP4 is "dead", however there are about two dozen or so of our clients that still are located on servers where PHP4 is used, and we won't get any server upgrades until around a year or two. I'm just about to start working on refactoring and improving our core web framework, which is now coded for the lowest common denominator, PHP4 ( eg all classes have var $foo ). I've never done any OO in PHP4 but I'm wondering if I should make different classes for the PHP versions, and based
