Simplifying an array

[mrgrammar]

Here's the code

$fieldname[0] = "FirstName";
$fieldname[1] = "LastName";
$fieldname[2] = "Title";
$fieldname[3] = "Organization";
$fieldname[4] = "Address1";
$fieldname[5] = "Address2";
$fieldname[6] = "City";
$fieldname[7] = "State";
$fieldname[8] = "Zip";
$fieldname[9] = "Country";
$fieldname[10] = "Phone";
$fieldname[11] = "Fax";
$fieldname[12] = "username";
$fieldname[13] = "URL";
$fieldname[14] = "GroupSize";
$fieldname[15] = "WhenDoingFundraiser";
$fieldname[16] = "SalesPriceRange";
$fieldname[17] = "FundraisingDollarGoal";
$fieldname[18] = "FundraiserType";
$fieldname[19] = "OrganizationDescription";
$fieldname[20] = "Comments";

	$ct = 0;	//the starting fieldname array number
	$tot = 20;	//the ending fieldname array number
	$body = "";
	while ($ct <= $tot){
		$body = $body.$fieldname[$ct].":  ".$_POST[$fieldname[$ct]]."/n";
	}

Is there a way that PHP will automatically count the number of items in an array so that $tot can automatically be totalled?

Use the [man]foreach[/man] construct to iterate over all the elements in the array.

Yes, count() or sizeof() will.

count is what I generally use for that -- mainly though I use it to find the last item in an array -- like so

$end_of_array = count($array) -1;

You need to subtract 1 so you get the index of it. Course, it only works if you use numbered indeces -- but you can manipulate it so much more easily that way anyway.

Though what you're doing looks like it could be accomplished with [man]implode[/man]...
