Can you include a function call within a double- or single-quoted string, as you can with a variable?

No. You must call functions outside quotation marks. However, you can break the string apart and place the function call between the parts of the string, using the concatenation operator to tie them together. For example:

$newstring = "I purchased".numPurchase($somenum)." items.";
