SplFileObject::fscanf

Parses input from file according to a format

&reftitle.description; public ``array``int``null```SplFileObject::fscanf` `string` `format` `mixed` `vars`

Reads a line from the file and interprets it according to the specified `format`.

Any whitespace in the `format` string matches any whitespace in the line from the file. This means that even a tab (`\t`) in the format string can match a single space character in the input stream.

&reftitle.parameters;

&strings.scanf.parameter.format;

`vars`

- The optional assigned values.

&reftitle.returnvalues;

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.
