filename

A URL can be used as a filename with this function if the fopen wrappers have been enabled. See fopen() for more details on how to specify the filename. See the Supported Protocols and Wrappers for links to information about what abilities the various wrappers have, notes on their usage, and information on any predefined variables they may provide.
open_mode

Приклад #1 SplFileObject::__construct() example
This example opens the current file and iterates over its contents line by line.
<?php
$file = new SplFileObject(__FILE__);
foreach ($file as $line_num => $line) {
echo "Line $line_num is $line";
}
?>
Наведений вище приклад виведе щось подібне до:
Line 0 is <?php Line 1 is $file = new SplFileObject(__FILE__); Line 2 is foreach ($file as $line_num => $line) { Line 3 is echo "Line $line_num is $line"; Line 4 is } Line 5 is ?>

When using URL as a filename, such as "http://..." or "php://stdin", and also have the fopen wappers on, and you get a 'RuntimeException' error, try using "NoRewindIterator" class to a SplFileObject instance.
<?php
$url = 'http://sample.com/data.csv';
$file = new NoRewindIterator( new SplFileObject( $url ) );
foreach ($file as $line_num => $line) {
echo "Line $line_num is $line";
}
?>
While opening a file, a rewind method will be called, but these URL iterators cannot be rewind, so you'll get a "Fatal error: Uncaught exception 'RuntimeException' with message 'Cannot rewind file ...'" error.
