Example #1 SplTempFileObject() example

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

= new SplTempFileObject();
$temp->fwrite("This is the first line\n");
$temp->fwrite("And this is the second.\n");
"Written " $temp->ftell() . " bytes to temporary file.\n\n";

// Rewind and read what was written
foreach (
$temp as $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.
