session_destroy
What's the purpose of this function? Because from what I can understand anybody could use de decode function and decode the encoded data....
session_encode
(PHP 4, PHP 5)
session_encode — 将当前会话数据编码为一个字符串

session_encode() returns a different format than serialize.
If you want to decode this format in python then "PHP Serialize implemented in Python" has special handling of this format using the session_encode and session_decode methods.

If anybody wants to encode any arbitrary array in the session serialization style, I have come up with the following function ( along with a corresponding decoding function in the session_decode notes ) to do just that.
Note the step I take to make sure we are not using a reference of the array, because calling session_raw_encode( $_SESSION ) ; will modify the real session when doing the recursion checks.
<?php
function session_raw_encode( $array, $safe = true ) {
// the session is passed as refernece, even if you dont want it to
if( $safe )
$array = unserialize(serialize( $array )) ;
$raw = '' ;
$line = 0 ;
$keys = array_keys( $array ) ;
foreach( $keys as $key ) {
$value = $array[ $key ] ;
$line ++ ;
$raw .= $key .'|' ;
if( is_array( $value ) && isset( $value['huge_recursion_blocker_we_hope'] )) {
$raw .= 'R:'. $value['huge_recursion_blocker_we_hope'] . ';' ;
} else {
$raw .= serialize( $value ) ;
}
$array[$key] = Array( 'huge_recursion_blocker_we_hope' => $line ) ;
}
return $raw ;
}
?>

$encodedData = session_encode();
$explodeIt = explode(";",$encodedData);

$sessGet = explode("|",$explodeIt[$i]);
$sessName[$i] = $sessGet[0];
if(substr($sessGet[1],0,2) == "s:") {
$sessData[$i] = str_replace("\"","",strstr($sessGet[1],"\""));
} else {
$sessData[$i] = substr($sessGet[1],2);
} // end if
} // end for
$result = array_combine($sessName,$sessData);
return $result;
}

session_encode() just return the session dataset in a formatted form
session_start();
$_SESSION['login_ok'] = true;
$_SESSION['nome'] = 'sica';
$_SESSION['inteiro'] = 34;
echo session_encode();
this code will print
login_ok|b:1;nome|s:4:"sica";inteiro|i:34;
