[SOLVED] How do I make an array when ...

[ryeman98]

So I've got this one script.

 

I need to know, how can I make an array work when I'm unsure of the size and values of it?

 

If you don't understand, I'll try to go more in-depth but it's tough.

I use arrays a lot without knowing how big they are etc... you need to explain in more detail...

 

Though you do realize there are functions that can count how big an array is etc.

I'll try as best as I can.

 

I have an array but I don't know how big it'll be.

I count the number of columns in the database and then select a random number. rand(1, $row['COUNT(id)']);

Then from that, it selects the column of the random number.

 

There is a column called probability. It calculates the chances of the thing being true out of 100. Then, whatever the probability number is, that is the size the array is going to be and another variable adds a random number to each array.

 

Then, there is some other stuff but it isn't relevant.

Bumping because I'm a little short for time

I really don't get what you're asking, sorry... hopefully someone else will.

Ok, this is what my array looks like:

$numbers = array();

 

And it's like that because I don't know how much info is going to be inserted.

[ryeman98]

Maybe this helps because this is what I want:

 

$numbers = array(Lowest, Highest);

 

And that sets the array's dimension ... does that help?

if your probability number is... lets say 17, then

 

howabout:

 

for ( $min= 1; $max<= 17; $counter ++) {

 

$myarray[] = $counter;

 

}

 

for output:

 

print_r($myarray);

print_r($myarray);

 

Well ... that helps out a little but I got that far. I guess I'm just looking for some kind of function to set the dimension of an array. Well hang on, this is how it works:

 

Say 5 was the prob number:

within your for loop

 

$numbers[$counter]; // Same as: $numbers['1'];

$numbers[$counter]; // Same as: $numbers['2'];

 

and so on ...
