Exemplo #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;
}
?>

O exemplo acima irá imprimir algo similar à:

Written 47 bytes to temporary file.

This is the first line
And this is the second.

Noting that when the tmp file exceeds memory limitations and is written to the system temp directory, it is deleted upon completion of the script it was initially created in. At least that is what I have seen and wanted to document for others since it wasn't clear.
