[PHP] Accessing a variable from inside a local function
Would anyone know how to resolve this scope problem? Or is this possibly
something PHP can't (yet) do?
The problem is to access a variable in a function foo from a function local
to foo.
- - -
function foo($var_foo)
{
$my_foo_local = 10; //How can I reach this from inside function bar(...?
function bar($var_bar)
{
return $my_foo_local+$var_bar+1; // Doesn't work, can't see
$my_foo_local
}
return bar($var_foo)+1;
}
if (foo(0)==12)
echo Yes! I did it!;
else
echo Nope. Sorry;

Re: [PHP] Re: Accessing a variable from inside a local function
Thanks for the good suggestion, a fully usable workaround if a cleaner
thing doesn't surface.
And for your response time.. well, I have had slower answers in
phone-conversations... :-)

Something like this is probably better handled by a class. Then you can
access class properties to do what you want.
Class yourclass
{
function foo()
{
$this-my_foo_local = 10;
}
function bar($var_bar)
{
return $this-my_foo_local+$var_bar+1;
}
}
$object = new yourclass();
$object-foo();
echo $object-bar(12);

Even though PHP lets you declare functions lexically within the scope of other functions snip Ouch! Thanks! Got that much wiser!

Re: [PHP] Using Post like Get
Hi, a cookie is path-specific - can that help you? Frank At 10:54 PM 8/23/2004, you wrote: What I'm trying to achieve is to have the same cookie IDENTIFY a user on different (or same) applications (on the same server), but require them to log in for each application, and get a different session.. Basically, to keep separate 'user trails and in process variables' for different tabs or windows in a browser. www.scotttrade.com does it somehow, and I see no GET variables on the URL. John W. Holmes wrote: Dennis Gearon wrote: With get varaibles, it's possible to always have get variables on a page, even without a form, by simply appending the Get variables to the end of the URL. Is there anyway to do the same with Post variables? For instance, a javascript that onUnload submit, or something? You can't just include POST variables in a link, if that's what you're going for. Perhaps some clunky javascript submitting a hidden form on an onclick method would get you close, but why even bother? Maybe you should just say what you're actually trying to achieve and why, then we could offer better alternatives. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] Re: Project-browser-function / required/included
Hi, thanks for your comment. Right, and similarly, it struck me that in case there are variable-names in the path, like in require_once $my_lib_dir . some_funcs.php; the variable $my_lib_dir could only be known at run-time and not by any simple script just scanning the source. Still, it would be possible to deliver a variable_name=value to the traversing function which would be good enough in most cases. May get around to it one day... Frank At 06:46 PM 7/22/2004, Jason Barnett wrote: Hmmm... this may be difficult to implement. For simple include/require trees it could be done quite easily... but __autoload opens up a whole other bag of worms. But now that I think of it I suppose you could create Reflections and get the location of class defintions from that. This might fit with something else I'm working on, I'll report back here if I come up with something useful. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] Project-browser-function / required/included
Hello, it would be nice to get a list of all required/included-files in a project. Would anyone know of such a tool, e.g. a PHP-function that would take a filename as input and then recursively scan for the tree of required/included files? Also HTML-links (A HREF...) and similar would be nice to be able to see - i.e. a function that takes a file as input and recursively checks for all links. TIA!

Do you mean ...to essentially run the PERL script in the background... If so you can just use the info in the manual: function.exec.html: Note: If you start a program using this function and want to leave it running in the background, you have to make sure that the output of that program is redirected to a file or some other output stream or else PHP will hang until the execution of the program ends. i.e. ?php ... exec(/my/perlscript /my/dump.txt 21); ... ? This will have your PHP script continuing without waiting for the perl script. - - - ...If I understood you correctly. HIH. Frank i'd like to kick off the php, and have the php/web app return. i could set some form of session var to trigger off of when the php is complete.. any thoughts/pointers/etc... AFAIK there's no way to do this. When the request ends (user hits stop, exit or die called) the process is ended. This includes children. If you could set it off asynchronously, there would be no way of knowing when it ended as the process wouldn't have access to that session any more. I would suggest setting a value in a table and have a cron job check for those values, run the script if it's supposed to, then update the table with the results. Then the PHP script can check the table to see it it's done. -- DB_DataObject_FormBuilder - The database at your fingertips http://pear.php.net/package/DB_DataObject_FormBuilder paperCrane --Justin Patrin-- -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] Function with Optional Arguments
You can use default arguments:
func foo($first, $second=2, $third=3 etc.
or look at
function func_num_args(...
