session_encode — Encodes the current session data as a session encoded string

### Description

session_encode(): string|false

session_encode() returns a serialized string of the contents of the current session data stored in the $_SESSION superglobal.

By default, the serialization method used is internal to PHP, and is not the same as serialize(). The serialization method can be set using session.serialize_handler.

### Parameters

This function has no parameters.

### Return Values

Returns the contents of the current session encoded, or `false` on failure.

### Notes

Warning

Must call session_start() before using session_encode().
