Examples

Example 52

Counting the number of items in a one dimensional array.

In this example, ArraySize is used to count the numbers in the array $arr.

$arr[0]="Mike Jones";

$arr[1]="Bill Carlson";

$arr[2]="Eve Smith";

$numberOfItems=ArraySize($arr);

When the script is run, $numberOfItems gets the value 3.

 

Example 53

Counting the number of items in a one dimensional array.

In this example, ArraySize is used to count the numbers in the array $arr.

$arr[0][0]="Mike";

$arr[0][1]="Jones";

$arr[1][0]="Bill";

$arr[1][1]="Carlson";

$arr[2][0]="Eve";

$arr[2][1]="Smith";

$numberOfItems=ArraySize($arr);

When the script is run, $numberOfItems gets the value 3, i.e. the same result as in the previous example.

 

Example 54

Adding items to arrays.

This example has two arrays:

•	$arrTele containing phone numbers.

•	$arrAmount containing call charges.

If a phone number for a specific call is found in $arrTele, the charge for the call should be added to the corresponding position in $arrAmount.

If the phone number is not found, the new phone number should be added to $arrTele and the new charge to $arrAmount. The ArraySize function specifies the position where to add the new number and charge at the end of the arrays.

$retIndex=FindInArray($arrTele, $noDialled);

if ($retIndex="-1")

   {

      $retSize=ArraySize($arrTele);

      $arrTele[$retSize]=$noDialled;

      $arrAmount[$retSize]=$callCharge;

   }

else

    $arrAmount[$retIndex]=$callCharge;
