If you want to search for files in the include path, you can use the optional second parameter and set it to "1 ".

// Obtain an array of web pages and print it
$ Fcontents = file ('http: // www.php.net /');
While (list ($ line_num, $ line) = each ($ fcontents )){
Echo"Line $ line_num:; ", Htmlspecialchars ($ line ),"
\ N ";
}

// Obtain a webpage to the string
$ Fcontents = join (', file ('http: // www.php.net /'));
?>
