serialize --
Generates a storable representation of a value
Description
string serialize (mixed value)
serialize() returns a string containing a
byte-stream representation of value that
can be stored anywhere.
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(). serialize()
handles all types, except the resource-type.
You can even serialize() arrays that contain
references to itself. References inside the array/object you
are serialize()ing will also be stored.
Note:
In PHP 3, object properties will be serialized, but methods are
lost. PHP 4 removes that limitation and restores both properties
and methods. Please see the Serializing Objects
section of Classes and
Objects for more information.
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), $PHP_AUTH_USER);
if (!odbc_execute ($stmt, &$sqldata)) {
$stmt = odbc_prepare($conn,
"INSERT INTO sessions (id, data) VALUES(?, ?)");
if (!odbc_execute($stmt, &$sqldata)) {
/* Something went wrong. Bitch, whine and moan. */
}
