SharePoint 2010 Powershell Series – Arrays and Loops

So now we are going to look at creating a simple array and then iterating through it, creating sites and lists as we go.
Line 1 creates an array with 3 values, Maths, English and Science.
Line 2 says, for each value in the array do the following.
Line 3 – 15 will create the site and lists in the same way I talked about in the last two posts.
I have tried to be a little clever in the creation of the sites by using the values within the array to name the lists and the site which is what the variable $sitename is for. 

$sites = ("Maths", "English", "Science")
ForEach ($sitearray in $sites)
{
$sitename = $sitearray
$SiteTitle = $SiteName + "" #in case you want to add anything else to title add it inside "" quotes.
$SiteUrl = "http://intranet/" + $sitename + "/"
$SiteTemplate = "STS#1"
Write-Host "Creating new site at" $SiteUrl
$NewSite = New-SPWeb -URL $SiteUrl -Template $SiteTemplate -Name $SiteTitle -UseParentTopNav
$web = Get-SPWeb $SiteUrl
$web.Lists.Add($sitename + " Announcements", $sitename + " site announcements list", 104)
$web.Lists.Add($sitename + " Links", $sitename + " site links list", 103)
$web.Lists.Add($sitename + " Documents", $sitename + " site documents library", 101)
$web.Lists.Add($sitename + " Pictures", $sitename + " site picture library", 109)
}

I hope this will help someone along with the rest of the series and is certainly a good reference for myself.
