Any whitespace in the <parameter>format</parameter> string matches any whitespace in the line from the file.

This means that even a tab (<literal>\t</literal>) in the format string can match a single space character in the input stream.

If only one parameter is passed to this method, the values parsed will be
|
|
returned as an array. Otherwise, if optional parameters are passed, the
|
|
function will return the number of assigned values. The optional
|
|
parameters must be passed by reference.
