Example #1 SplTempFileObject() example

This example writes a temporary file in memory which can be written to and read from.

<?php $temp = new SplTempFileObject( $temp->fwrite("This is the first line\n" $temp->fwrite("And this is the second.\n" echo "Written " . $temp->ftell() . " bytes to temporary file.\n\n"; // Rewind and read what was written $temp->rewind( foreach ($temp as $line) {     echo $line; } ?>

The above example will output something similar to:

Written 47 bytes to temporary file. This is the first line And this is the second.
