session_encode — Kodiert die Daten der aktuellen Session als Zeichenkette
session_encode() gibt eine Zeichenkette mit dem kodierten Inhalt der aktuellen Session zurück.
Gibt Inhalt der aktuellen Session kodiert zurück.
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.
http://www.hurring.com/scott/code/python/serialize/
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 ;
}
?>
<?php
session_start();
# boolean type
$_SESSION['logged'] = true;
# string type
$_SESSION['name'] = "Onur Yerlikaya";
# integer type
$_SESSION['age'] = 17;
// logged|b:1;name|s:14:"Onur Yerlikaya";age|i:17;
function readSessions() {
$encodedData = session_encode();
$explodeIt = explode(";",$encodedData);
for($i=0;$i<count($explodeIt)-1;$i++) {
$sessGet = explode("|",$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;
}
/*
readSessions Func shows encoded data in array
Array
(
[logged] => 1
[name] => Onur Yerlikaya
[age] => 17
)
*/
print_r(readSessions());
?>
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;
