Massives -> array_splice -> are duplicated
Hi! I have such a trouble. I make a class and in it
var $id;
var $name;
In the initialization these variables become a blank massive:
$this->$id = array();
$this->$name = array();
Further working with class I call function of this class containing following code:
array_splice($this->$id, count($this->$id), 0, $newId); array_splice($this->$name, count($this->$name), 0, $newCategoryName);
where $newId and $newCategoryName are the values which should be added to the massives.
Everything would be all right but accomplishing of the last two strings results into increasing a massive twice, i.e. after the accomplishment we have:
count($this->$id) = 2
count($this->$name) = 2
though it should be:
count($this->$id) = 1
count($this->$name) = 1
Why is it so?
Before array_splice another code is accomplished, perhaps, this also should matter:
$newId = 0;
if (count($this->$id) > 0) {
$newId = max($this->$id);
}
$newId += 1;PHP 4.5 @ windows XP
P.S. Sorry if my explanations aren??™t clear??¦

Re: Massives -> array_splice -> are duplicated
As I understand you have some programming experience??¦ In what language?

Re: Massives -> array_splice -> are duplicated
Then I don??™t understand your phrase

Why cannot you check on your own if it matters or not?
Why cannot you write a text example without classes, methods and ???another codes??™?
Why don??™t you reduce the number of unknown values in the task by minimizing them?
As to your question??¦
Frankly speaking, I didn??™t understand it completely??¦
$newId and $newCategoryName are the values which should be added to the massives
If you need to add
1) why such an original function as array_splice is used for it?
2) why are you surprised with the fact that massive size increased?

Re: Massives -> array_splice -> are duplicated

I??™ve checked it:
$id = array();
$name = array();
$newId = 0;
if (count($id) > 0) {
$newId = max($id);
}
$newId += 1;
array_splice($id, count($id), 0, $newId);
array_splice($name, count($name), 0, "some text ");
echo count($name);It functions properly, count($name) = 1.
1) why such an original function as array_splice is used for it?
I??™m new to PHP and haven??™t studied all the functions yet. If there are some other functions, show them to me and I will use them.
2) why are you surprised with the fact that massive size increased?
I??™m surprised with the fact size of each massive in the object increases by each call of array_splice i.e. the same code placed within class returns count($name) = 2 instead of count($name) = 1:
array_splice($id, count($id), 0, $newId); array_splice($name, count($name), 0, "some text");
As you can see I insert new $newId value into $id massive and in the next string $name massive is also a new value. Within class after accomplishment of the first string:
array_splice($id, count($id), 0, $newId);
$name massive also increases somehow?!
Sure, I wrote like this as well:
array_splice($id, count($id), 0, $newId); $this->$name[count($this->$name)] = "some text ";
And it works. But is it correct? Will I have any problems with it in the future? And why all the massives increase?
