PHP serialize

PHP original manual for serialize [ show | ]


(PHP 4, PHP 5)

serializeGenerates a storable representation of a value


string serialize ( mixed $value )

Generates a storable representation of a value

This is useful for storing or passing PHP values around without losing their type and structure.

To make the serialized string into a PHP value again, use unserialize().



The value to be serialized. serialize() handles all types, except the resource-type. You can even serialize() arrays that contain references to itself. Circular references inside the array/object you are serializing will also be stored. Any other reference will be lost.

When serializing objects, PHP will attempt to call the member function __sleep prior to serialization. This is to allow the object to do any last minute clean-up, etc. prior to being serialized. Likewise, when the object is restored using unserialize() the __wakeup member function is called.

Note: Object's private members have the class name prepended to the member name; protected members have a '*' prepended to the member name. These prepended values have null bytes on either side.

Return Values

Returns a string containing a byte-stream representation of value that can be stored anywhere.


Example #1 serialize() example

// $session_data contains a multi-dimensional array with session
// information for the current user.  We use serialize() to store
// it in a database at the end of the request.

$conn odbc_connect("webdb""php""chicken");
$stmt odbc_prepare($conn,
"UPDATE sessions SET data = ? WHERE id = ?");
$sqldata = array (serialize($session_data), $_SERVER['PHP_AUTH_USER']);
if (!
odbc_execute($stmt, &$sqldata)) {
$stmt odbc_prepare($conn,
"INSERT INTO sessions (id, data) VALUES(?, ?)");
    if (!
odbc_execute($stmt, &$sqldata)) {
/* Something went wrong.. */


Version Description
4.0.7 The object serialization process was fixed.
4.0.0 When serializing an object, methods are not lost anymore. Please see the Serializing Objects for more information.


Note: It is not possible to serialize PHP built-in objects.
