# fscanf

(PHP 4 >= 4.0.1, PHP 5)

fscanf — Parses input from a file according to a format

### 설명

mixed fscanf ( resource `$handle` , string `$format` [, mixed `&$...` ] )

The function fscanf() is similar to sscanf(), but it takes its input from a file associated with `handle` and interprets the input according to the specified `format` , which is described in the documentation for sprintf().

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

Each call to fscanf() reads one line from the file.

### 인수

`handle`

  일반적으로 fopen()으로 생성하는 파일 시스템 포인터 resource.

`format`

  The specified format as described in the sprintf() documentation.

`...`

  The optional assigned values.

### 반환값

If only two parameters were passed to this function, 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.

### 변경점

버전 | 설명
--- | ---
4.3.0 | Before this time, the maximum number of characters read from the file was 512 (or up to the first \n, whichever came first). But now, arbitrarily long lines will be read and scanned.
