Does PHP Have a "built-in" iterator in a Foreach loop?

I'm using a foreach loop to go through the REQUEST array, as I want to have an easy way to utilize the REQUEST array's keys and values.

However, I also want to have a numerical index of how many times the loop has run, as I'm writing a spreadsheet with PHPExcel, and I want to use the SetCellValue function. I'm thinking something like this:

foreach( $_REQUEST as $key => $value){
    $prettyKeys = ucwords(preg_replace($patt_underscore," ",preg_replace($patt_CC,"_",$key)));
    $prettyVals = ucwords(preg_replace($patt_underscore," ",preg_replace($patt_CC,"_",$value)));
    // Replace CamelCase with Underscores, then replace the underscores with spaces and then capitalize string
    // "example_badUsageOfWhatever" ==> "Example Bad Usage Of Whatever"


    $myExcelSheet->getActiveSheet()->SetCellValue( "A". $built-in-foreach-loop-numerical-index ,$prettyKeys);
    $myExcelSheet->getActiveSheet()->SetCellValue( "B". $built-in-foreach-loop-numerical-index ,$prettyVals);
}

I know I can easily implement something like $c = 0 outsite the foreach and then just increment it each time the loop is run, but is there something cleaner?

PHP's foreach does not have this functionality built in (per the manual). Use a for loop to have an iterator or implement it yourself.
