Example of array usage

This script is an example on how to builds arrays. The following variables are used:

•	$ca_no_dialled – at the time the script is called, this variable contains a phone number from a field in a phone bill.

•	$ca_call_charge – contains the amount charged for the corresponding call.

•	$arrtele – the array containing phone numbers.

•	$arramt – the corresponding array of summed costs for calls placed to the phone number.

•	$totalcharge – a sum that starts out empty and gets $ca_call_charge added to it each time the script is run. It ends up a sum of all the call charges in the phone bill.

•	$subtotalcharge – a similar sum, but it is read and reset to 0 every now and then (each page) by a different script.

 

//Add charge for this call to sum. $totalcharge = $totalcharge + $ca_call_charge; //Add charge for this call to subtotal. $subtotalcharge = $subtotalcharge + $ca_call_charge; // See if the current phone number is already in the array of phone numbers. $retno = FindInArray($arrtele, $ca_no_dialled); if($retno = "-1") // If -1, then the phone number is a new one. { // Determine current size of array, so that we know where to append. $retsize = ArraySize($arrtele); /* Add the new phone number to our phone numbers array, and put the corresponding cost in the $arramt array.*/ $arrtele[$retsize] = $ca_no_dialled; // The new phone number $arramt[$retsize] = $ca_call_charge; // amount charged } else /* The current phone number was found in the array. Add the amount charged to the corresponding $arramt element.*/ $arramt[$retno] = $arramt[$retno] + $ca_call_charge;
