session_decode

Function name: session_decode()

Applicable version: PHP 4, PHP 5, PHP 7

Function usage: The session_decode() function is used to decode and store an encoded session data into the current session. Normally, session data is encoded and stored in a file or database using the session_encode() function. When it is necessary to restore session data, you can use the session_decode() function to decode and restore it to the current session.

Function syntax: bool session_decode(string $data)

Parameter description:

• $data: Required, represents the encoded session data, which can be a string or binary data.

Return value:

• Return true if decoding is successful; otherwise return false.

Example: <?php // Read encoded session data from a file $encodedData = file_get_contents('session.txt');

// Decode and restore the session data to the current session if (session_decode($encodedData)) { echo "Session data decoding successfully!"; } else { echo "Session data decoding failed!"; } ?>

In the example above, we read an encoded session data from the file and decode it and restore it to the current session using the session_decode() function. If the decoding is successful, "Session data decoding is successful!" will be output; otherwise, "Session data decoding failed!" will be output.
