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;}?>
