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.

Beispiel #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;
}
?>Das oben gezeigte Beispiel erzeugt eine ähnliche Ausgabe wie:
Written 47 bytes to temporary file. This is the first line And this is the second.
