How to create a dynamic array???

Anon

Hi, I was wondering if anyone can help me create a dynamic array.

I have to read some values into a file and some of these values will be repeated.

I want to know the total of each value.

Say I read the following values :
4,5,7,5,4,1,4

I thought of using a switch case but it wouldn't make sense to have a switch case for so many values in between 1 and 10,000.

Thanks a lot in advance for your time.

I don't know how you are reading the values, but the easiest way to do what you are saying is something like:

while (however you are reading the value) {
  $counterArray[$readValue]++;
}

when you are done reading the values, the array will contain the number of each value read. ie: <b>$counterArray[5]</b> will contain the number of 5's you read.

NOTE
This method is good if the values you are reading are relatively small (0-999). If the values you are reading are large or vary wildly, I would create a two dimensional array that holds the value and then the count as opposed the above method that uses the value as the index.
