Listing All SharePoint Server Features of Web Application dynamic by power shell

1. Writing the function to export all features of web application with parameter

function Get-SPFeatureActivated

{
[CmdletBinding()]
param(
    [parameter(Mandatory=$true)][string]$Url,#Input your URL of web application
    [parameter(Mandatory=$true)][string]$Path,#Input your file name which you want to export like (c:\features.csv)
    [Parameter(position = 1, valueFromPipeline=$true)]#Default para
    [Microsoft.SharePoint.PowerShell.SPFeatureDefinitionPipeBind]   
    $Identity
)#end param
    Begin
    {       
        $results = @()
       
        $params = @{}
    }
    Process
    {
        if([string]::IsNullOrEmpty($Identity) -eq $false)
        {
            $params = @{Identity = $Identity
                        ErrorAction = "SilentlyContinue"
            }
        }   

        # Get web application URL
    $webApplication = Get-SPWebApplication -Identity $Url
        foreach($webApp in $webApplication)
        {
            $results += (Get-SPFeature -WebApplication $webApp -Limit All @params |
                             % {Add-Member -InputObject $_ -MemberType noteproperty -Name Url -Value $webApp.Url -PassThru} |
                             Select-Object -Property Scope, DisplayName, Id, Url)

            # check site collection features in current web app
            foreach($site in ($webApp.Sites))
            {
                $results += (Get-SPFeature -Site $site -Limit All @params |
                                 % {Add-Member -InputObject $_ -MemberType noteproperty -Name Url -Value $site.Url -PassThru} |
                                 Select-Object -Property Scope, DisplayName, Id, Url)
                                
                $site.Dispose()

                # check site features in current site collection
                foreach($web in ($site.AllWebs))
                {
                    $results += (Get-SPFeature -Web $web -Limit All @params |
                                     % {Add-Member -InputObject $_ -MemberType noteproperty -Name Url -Value $web.Url -PassThru} |
                                     Select-Object -Property Scope, DisplayName, Id, Url)

                    $web.Dispose()
                }
            }
        }
    }
    End
    {
        $results > $Path
    }
}
