The maximum amount of memory (in bytes, default is 2 MB) for the temporary file to use. If the temporary file exceeds this size, it will be moved to a file in the system's temp directory.
If max_memory

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.
