Display a value of a powershell array in html

Question

I have this array:

$server = @("value 1", "value 2")

and this array, that will be a part of a table:

$HtmlHeader= @"
<tr>
<th class="vcenter" colspan="5">$server[$i]</th>
</tr>
<tr>
<th class="colnames">Nome</th>
<th class="colnames">Dimensione (MB)</th>
<th class="colnames">VM</th>
<th class="colnames">Stato VM</th>
<th class="colnames">Data Creazione</th>
</tr>
"@

but the output is:

value 1 value 2[1]

and

value 1 value 2[2]

How can I fix it, the second array is part of a for cycle and $i is defined in that.

You probably need to change $server[$i] to $($server[$i]) in the multiline string. However, it's hard to tell, since you didn't show that much of your code.

You can't embed arrays in strings like that. PowerShell interpets $server[$i] as different strings, i.e as $server then [$i]. This results in the entire array getting spit out, followed by the value of $idx. I like to use format strings instead of embedding variables directly in strings. That way I don't have to worry about all the ways embedding variables can go wrong:

$HtmlHeader= @"
<tr>
  <th class="vcenter" colspan="5">{0}</th>
</tr>
<tr>
  <th class="colnames">Nome</th>
  <th class="colnames">Dimensione (MB)</th>
  <th class="colnames">VM</th>
  <th class="colnames">Stato VM</th>
  <th class="colnames">Data Creazione</th>
</tr>
"@ -f $server[$i]
