[PHP] sessions

Rozhodol som sa, ze sa naucim pracovat so sessions...

Mam PHP 4.3.6, sessions enablovane...

Nizsie uvedeny kod mi nefunguje, a neviem preco...

Session mi to v prislusnom adresari normalne vytvori, ale po kliku na link, sa to nikdy nedostane k ELSE...

Nemam ponatia, preco to nefunguje a zacina ma to pekne srat :evil:

Kód:

---

<?php
if &#40;!session_is_registered&#40;'count'&#41;&#41; &#123;
    session_save_path&#40;'c&#58;/cestaktempdiru/tmp/'&#41;;
    session_register&#40;'count'&#41;;
    $count = 1;
&#125;
else &#123;
    $count++;
&#125;
?>


Hello visitor, you have seen this page <?php echo $count; ?> times.

Any ideas ???

Nemas tam

Kód:

---

  session_name("neco");
  session_start();

---

To musis mit v kazdem skriptu na zacatku, jinak ti nebude session fungovat.

Jinak vkladat do session muzes i proste takhle:

$_SESSION["aaa"] = "bbb";

PS: Uz je PHP 4.3.11 :-) (a taky 5.0.4)

session_name neni potreba... Staci session_start... Funguje mi to uplne v poho...

A není od věci ukončit stránku kódem:

Kód:

---

Session_write_close();

session_start...
Tych ludi, co robili phpManual, by sa zislo obcas preplesknut :o (podla helpu sa pouzitie session_register zaobide bez session_start)

Netreba, pri vytvoreni session pomocou session_register, si meno vytvori automaticky podla parametra funkcie...

Jj, tak jsem to myslel... No nic si z toho nedelej, ja zas myslel onehda, ze se to musi pouzivat JEN pri prvni praci s tou promennou... Proste ze tim STARTem ty promenny nejak "nastartujes" a pak uz to jede :) Ale ve skutecnosti to musi byt na zacatku kazdyho souboru, kde clovek se sessions dela... :roll:

Pouzivani session_register se nedoporucuje, viz php manual, mam radeji prime odkazovani v poli, mam pak pocit, ze mam veci vic pod kontrolou

Kód:

---

<?php
// Use of session_register&#40;&#41; is deprecated
$barney = "A big purple dinosaur.";
session_register&#40;"barney"&#41;;

// Use of $_SESSION is preferred, as of PHP 4.1.0
$_SESSION&#91;"zim"&#93; = "An invader from another planet.";

// The old way was to use $HTTP_SESSION_VARS
$HTTP_SESSION_VARS&#91;"spongebob"&#93; = "He's got square pants.";
?>

Session variables: $_SESSION
Note:
Introduced in 4.1.0. In earlier versions, use $HTTP_SESSION_VARS.

An associative array containing session variables available to the current script. See the Session functions documentation for more information on how this is used.

This is a 'superglobal', or automatic global, variable. This simply means that it is available in all scopes throughout a script. You don't need to do a global $_SESSION; to access it within functions or methods, as you do with $HTTP_SESSION_VARS.

$HTTP_SESSION_VARS contains the same information, but is not an autoglobal.

A jeste k session_unregister

Citace:

---

If $_SESSION (or $HTTP_SESSION_VARS for PHP 4.0.6 or less) is used, use unset() to unregister a session variable. Do not unset() $_SESSION itself as this will disable the special function of the $_SESSION superglobal.

Atd proste viz. php manual
