php://memory And Maxmemory

By Alexandre Daubois

php://memory is a stream that lives in RAM.

php://temp starts in RAM, spills to disk after 2MB (configurable, see below!).

No tmpfile(). No temp directory. No cleanup.

Perfect for building files in memory before sending in PHP!

Did you know the maxmemory trick?
