Delete multiple site collections using SharePoint Power Shell Script

This script will delete site collections from the SharePoint server completely. But we need to provide the site collection names to the Power Shell Script as a ";" separated values.

Power Shell Script:

Ex: $SiteCollection = "http://SP-S2010/sites/TeamSite1;http://SP-S2010/sites/TeamSite2" 

$SiteCollection = "http://SP-S2010/sites/TeamSite1;http://SP-S2010/sites/TeamSite2" 

$SiteArray = $SiteCollection.Split(";")

foreach($Site in $SiteArray) 

{  

    Remove-SPSite –Identity $Site –GradualDelete –Confirm:$False

}
