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 ;
   
}

?>

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;
