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(). 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.
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.
Example 1. fscanf() Example
<?php $handle = fopen("users.txt", "r"); while ($userinfo = fscanf($handle, "%s\t%s\t%s\n")) { list ($name, $profession, $countrycode) = $userinfo; //... do something with the values } fclose($handle); ?>
Example 2. Contents of users.txt

Note:
Prior to PHP 4.3.0, the maximum number of characters read from
the file was 512 (or up to the first \n, whichever came first).
As of PHP 4.3.0 arbitrarily long lines will be read and scanned.
