FindStringExactInArray(array_name, str);

array_name	A string specifying the name of the array.

Example

This example has two arrays:

•	$arrTele containing phone numbers.

•	$arrAmount containing call charges.

The FindStringExactInArray function is used to search for the phone number in $arrTele.

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.

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

if ($retIndex="-1")

   {

      $retSize=ArraySize($arrTele);

      $arrTele[$retSize]=$noDialled;

      $arrAmount[$retSize]=$callCharge;

   }

else

    $arrAmount[$retIndex]=$callCharge;
