session_encode php functions offers a convenient way of converting all of the data in a session to a string. The “session_encode()” function encodes the current session data as a string.
PHP session_encode() Function – Syntax
session_encode(void)
session_encode php – Session Encode Decode functions in PHP
- session_encode()
- session_decode()
What is session_encode Function?
session_encode php – session handling is a way to make the data available across various pages of a web application.
PHP Session Encode Decode Example
Encoded Session Data:
"; print $dt_encoded_sss . "
"; // Changing session values $_SESSION['computer_code'] = "2000"; $_SESSION["logged_in"] = "no"; // printing $_SESSION print "SESSION Array:
"; print ""; print_r($_SESSION); print "";
session_decode($dt_encoded_sss);
// printing Reloaded $_SESSION
print "Reloaded SESSION Array:
";
print ""; print_r($_SESSION); print "";
?>Results:
Encoded Session Data: computer_code|s:4:"8888";logged_in|s:3:"yes"; Changed SESSION values: Array ( [computer_code] => 2000 [logged_in] => no )Reloaded SESSION Array: Array( [computer_code] => 8888 [logged_in] => yes )Example :
"; echo session_encode(); ?>PHP – Cookies and Sessions – session_encode()
"; } else { mysql_query($query_update) or die ("db query failed"); print "Session data updated in db!
"; } // remove the session variable print "Session with id " . session_id() . " saved!"; unset($_SESSION["product"]); session_destroy(); ?>Results
Session data inserted into db! Session with id 2459d55b7c83d8ba0b1bb5f84b895f6f saved!Encoding and Decoding PHP Session Variables
In PHP, you can use session_encode() and session_decode() functions to encode and decode session data. These functions allow you to serialize and deserialize session data into a string representation that can be stored or transmitted.
Here’s an example of how to use these functions:
// Start the session session_start(); // Set some session data $_SESSION['username'] = 'john'; $_SESSION['email'] = '[email protected]'; // Encode the session data $encoded = session_encode(); // Decode the session data session_decode($encoded); // Access the decoded session data echo $_SESSION['username']; // Outputs: john echo $_SESSION['email']; // Outputs: [email protected]In this example, we start the session and set some session data. We then use session_encode() to serialize the session data into a string, which we can store or transmit as needed. We then use session_decode() to deserialize the string back into session data, which we can then access as normal using the $_SESSION superglobal.
Note that when using session_encode() and session_decode(), the session must be started first using session_start(). Also, the serialized string representation of the session data can be quite large, so it’s important to make sure that your storage or transmission method can handle the size of the data.
