Powershell Null Coalescing

($PhysicalPath, "c:\inetpub\wwwroot" -ne $null)[0] # null coalescing

# Based on the order of operations, this works in following order:

#     The , operator creates an array of values to be tested.
#     The -ne operator filters out any items from the array that match the specified value--in this case, null. The result is an array of non-null values in the same order as the array created in Step 1.
#     [0] is used to select the first element of the filtered array.

# Simplifying that:

#     Create an array of possible values, in preferred order
#     Exclude all null values from the array
#     Take the first item from the resulting array
