Re: [PHP] trying to do too much with functions?
John Holmes elegantly wrote:
From: Justin French [EMAIL PROTECTED]
I have a few functions with way too many parameters in them, or
functions which have a non-obvious order of parameters which I
constantly have to refer to as I'm working. Since I'm using PHP as
my templating language (none smarty here!) as well as the programming
language. So I've been looking for some alternatives...
My main objectives:
1. have all parameters optional
2. have a mixed order for the paramaters
Other languages seem to do this well (Ruby, or perhaps RubyOnRails
seems good at it), but in PHP I can only see a few options... I'm
hoping someone might offer a few more ideas.
? $params = array('a'='123','b'='456'); echo doStuff($params); ?
?=doStuff(array('a'='123','b'='456'))?
?=doStuff('a=123','b=456')?
?=doStuff('a','123','b','456'); ?
?=doStuff(a='123' b='456')?
So, is that it? Have I thought of all possible options?
Have you looked at the Function Handling Functions?
http://www.php.net/manual/en/ref.funchand.php
An array is probably your best bet, though, since you want to have
mixed orders. The only way you'd be able to identify what parameter is
which is by using the keys of the array, then.
---John Holmes...
OR, if you really wanted to get crazy, you could do it like objective-C.
function blah()
{
// contents
}
call the function like so
$classobject-function(firstname:jim, lastname:steve );
within the function, you could call func_get_args, then map your
variables to an array using list($var, $val) = explode( :, $arg[x] )
of course, if you had a : (colon) in either string that exact solution
wouldn't work. but that's not the point of this lesson.
i should note that I've considered doing this before and I didn't. Now
i just use default values of NULL.

Re: [PHP] unlink() rmdir() ... Problems.
PHP probably does not have permission to change those files. chmod 777
and it should work.
However now those files are writable by anyone. If you're on a shared

Ave,
I do not really know what the problem is because I don't get an error, and
in fact my scripts execute fine... Except that, niether is the directory
deleted, nor is the file deleted. Only corresponding database entries are
deleted which I specify in my SQL code.
There are 2 different functions in 2 separate places in my File Manager.
1 function deletes the User including his Folder
The other deletes a particular file.
The code I'm using to delete the User his Folder is:
?php
if($delete_user) {
$db = mysql_connect(localhost,usr,pwd);
mysql_select_db(mydb,$db);
$sql = DELETE FROM user where login = '$user';
$result = mysql_query($sql) or die(There is a problem.);
$sql2 = DELETE FROM file where login = '$user';
$result2 = mysql_query($sql2) or die(There is a problem.);
rmdir (imsafm/$user);
echo brbismallUser $user deleted./small/i/bbr;
}
?
The name of Folder of a user is the same as his Login.
Anyhow... The above code doesn¹t generate any error, and in fact does delete
the database entries from the table... But it doesn¹t remove the user¹s
directory. Why is that?
Similarly, this is the code for deleting the file:
?php
$db = mysql_connect(localhost,usr,pwd);
mysql_select_db(mydb,$db);
$sql = DELETE FROM file where ID = '$ID';
$result = mysql_query($sql) or DIE(Cannot Do!);
unlink($P/$F);
echo centerFile Deleted/center;
?
Again, no error... The entries in the table get deleted.. But file remains
in the directory.
Any suggestions?

The Location header requires an absolute URL. Also, this is the header you

Location: loginForm.php%3Ferror%3DIncorrect+password
I doubt that's the URL you meant. URL encode the value of URL variables,
not the entire URL.
Lastly, I hope you're not blindly displaying $_GET['error'] on your
loginForm.php page, otherwise you have a cross-site scripting
