fscanf
(PHP 4 >= 4.0.1)
fscanf -- Parses input from a file according to a format
Description
mixed fscanf ( resource handle, string format [, string
var1])
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. 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.
