Unknown values in Array

[ILikeBread]

Hi

 

Hopefully someone can help me.

 

Using the example below

$NumberArray= array(1,2,3,4,5,6);

 

If i didn't know how many values i wanted to add until i recieved information from the database at page load, how would i program an array in this format?

 

In the above example i know i need 6 places in the array.

But i want something like

$NumberArray= array(VARIABLE NUMBER OF SLOTS);

 

To save people showing me this as an answer "$NumberArray[n]" that is not what i am after.

 

I was thinking something like this

array(  for ($i = 0; $i <= $ID; $i++)  {  $NumberArray);  }  );

But it doesnt work

 

Thanks in advance.

unlike other programming languages..in PHP you don't have to declare an array's length before using it

if that's what you're really asking.

 

but usually to populate an array with the results of a mysql result

it looks like this

$row = null; //Row begins as nothing //Also, you don't have to declare this either I just put it for demonstration

while($row = mysql_fetch_array()) {

  echo $row['name'];

}

//Now row is an array of....I really don't know what size

prints the Names of all that are in the results

Thats sort of what i am after but also not quite it.

 

I'll go into more detail.

I currently use your exact script to pull my data out of my MySQL database. I then filter the data into an array named "$Profit[n]"

"$Profit[n]" changes how many things go into it on almost a daily basis.

 

Lets say Profit[n] looks like this

Profit[0] = 2;

Profit[1] = 4;

Profit[2] = 6;

 

I then want to be able to add it into the format

array("ALL PROFIT RECORDS");

 

(using the example above)

array(Profit[0], Profit[1], Profit[2]);

 

My main problem is that I can't seem to replicate the Profit[n] in the new array at run time.

 

I realize i am replicating data but please humor me.

So........you're trying to put an array into an array?

 

what's wrong with doing this

 

$allProfits[] = $Profit[0];

$allProfits[] = $Profit[1];

$allProfits[] = $Profit[2];

$allProfits[] = $Profit[3];

<?php

foreach ($profit as $key => $value) {

  $newArray[$key] = $value;

}

?>

 

would do that, it would use the keys from the current array as the new keys in this one. but its pretty much just making a copy of that array with a new name isnt it?
