global only really makes sense in the context of INSIDE a function (or
method of a class)
So *where* did you declare it global?
You probably want to take out the global unless it is inside of a
function() { }
So I want to ask:
1. Is my use way right?
2. if I want to track a variable value how it changed between php
functions,
besides I print out it's value, Is there any other way to do it?
There are IDEs you can use to watch variables as a script executes.
Zend IDE
Komodo
are the ones I remember as good from when I last looked at IDEs
YMMV

[PHP] How can I track the value in php
Hi, I am php beginner, I have a question: in my index page, I firstly inlcude_once a A.php file, where i defined an array, secondly I include another .php file named B.php, where I want to use the array, I have claimed it as global type, but it seems I can't retrieve any value from the array. So I want to ask: 1. Is my use way right? 2. if I want to track a variable value how it changed between php functions, besides I print out it's value, Is there any other way to do it? Any suggestion and solution welcomed! Thanks in advance.
Re: [PHP] How can I track the value in php
in my index page, I firstly inlcude_once a A.php file, where i defined an array, secondly I include another .php file named B.php, where I want to use the array, I have claimed it as global type, but it seems I can't retrieve any value from the array. When you include a PHP file, it will be executed in the current context (AFAIK). If you're not including it from a function, then it should be global automatically. The global keyword makes variables in functions global. Maybe this is obvious, but are you sure you have ?php in the B.php? What does var_dump($xxx); say, if $xxx is the array name? -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
