powershell recursive function array values disappears

Before calling recursive function - RecursiveWebs, $webinfo.count is 1. During the execution of recursive function, count is increased but as soon is recursive function is completed and control return to main function, $webinfo.count again decreases to 1.

function RecursiveWebs($web){
    $Properties = @{
        Title = $web.Title
        URL = $web.Url
    }

    $webinfo += New-Object psobject -Property $properties       
    foreach($w in $web.Webs)
    {
        if ($w.Webs.Count -gt 0){
         RecursiveWebs $w
        }
    }
}

$global:webinfo = @() 
$sites = Get-SPOSite -Limit All
foreach ($site in $sites) {
    Write-Host $site.Url
    try {
        $Properties = @{
            Title = $site.Title
            URL = $site.Url            
            NoOfSubsites = $site.Webs.Count        
        }    

        $webinfo += New-Object psobject -Property $properties

        if ($site.Webs.Count -gt 0)
        {            
            RecursiveWebs $site
        }        
    }
    catch 
    {       
        Write-Host $_ -ForegroundColor Red
    }
}

Replaces $webinfo with $Global:webinfo everywhere in the code and it did the trick
