Powershell Script to list pdf files in a directory

Question

Hey Scripting guy, I read few of your forum solutions for the scripts and was really enthralled to embrace this powershell scripting, thanks for the motivation.
I am still a learner and want to learn more, I had to do a script on generating an excel report which consisted of number of files of files in PDF format for each directory and sub-directory in the path.
I used the,
get-childitem $Path -recurse | where {$_.Extension -match "pdf"}
command, all I wanted to know is how to count the number of PDF files in each sub directory, please help me out,
Thanks in advance

Ok, let's have some fun :)
function Count-FilesRecursive{
Param(
[parameter(Mandatory = $true, Position = 0)]
[string]$Path,
[parameter(Mandatory = $true, Position = 1)]
[string]$Filter
$SB_recursive = {
[System.IO.Directory]::GetDirectories($args[0])|ForEach-Object {
Try{
$i = ([System.IO.Directory]::GetFiles($_,$Filter)).Count
Catch [UnauthorizedAccessException] {
$i = 0
"{0,-10} {1}" -f $i, $_
Try{
$SB_recursive.Invoke($_)
Catch [UnauthorizedAccessException] {}
"{0,-10} {1}" -f "Number of files", "Path"
"{0,-10} {1}" -f "---------------", "----"
$SB_recursive.Invoke($Path)
Count-FilesRecursive -Path C:\users -Filter '*.pdf'
