Syntax: mixed fscanf (int handle, string format [, String var1 ...])

Description:

This function fscanf () is similar to sscanf (), but it takes its input from a file, and interprets its input according to the format specified. If only two parameters are passed to this function, the returned value will be an array, otherwise, if there is a pass of non-essential parameters, this function will return the number of allocation (assigned) values, and non-essential parameters must be passed in accordance with the relationship.

Example:

<?php

$fp = fopen ("Users.txt", "R");

while ($userinfo = fscanf ($fp, "%s\t%s\t%s\n")) {

List ($name, $profession, $countrycode) = $userinfo;

... do something with the values

}

Fclose ($FP);

?>
