fscanf
(PHP 4 >= 4.0.1, PHP 5)
fscanf — Parses input from a file according to a format
Description
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.
Parameters
Return Values
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.
ChangeLog
| Version | Description |
|---|---|
| 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. |
