Storing certain array content in a variable

Question

I have the following array:

$webApplications = Get-SPWebApplication | Select-Object Url

which gives output similar to this:

http://testportal.*******de
http://testportal2.******de

I would like the output to be numbered like this for example:

1- http://testportal.*******de
2- http://testportal2.******de

and then store them in variables and have the user be able to choose the portal they want by typing in only the number of the portal. I tried something like this to store them in variables (not sure if it's the right approach):

$Variable1 = $webApplications[0]
$Variable2 = $webApplications[1]
$SelectedURL = Read-Host 'choose your portal by selecting a number'

I just can't seem to figure out how to list the content of the array with numbers on the side and then call it back for the $SelectedURL variable.

Don't do what you're trying to do. Using dynamic variable names is an anti-pattern.

Do something like this instead:

for ($i=0; $i -lt $webApplications.Count; $i++) {
    '{0} - {1}' -f ($i+1), $webApplications[$i]
}
[int]$SelectedURL = Read-Host 'choose your portal by selecting a number'

$webApplications[($SelectedURL - 1)]

This gave me the result i was hoping for, thank you very much, if you could maybe explain to me this real quick i'd appreciate it :) ($i=0; $i -lt $webApplications.Count; $i++) { '{0} - {1}' -f ($i+1), $webApplications[$i

The loop is a regular for loop and in the body of that loop I'm using the format operator for creating formatted output.
