session register VS $_SESSION[]

 

Which is best method?

Thank you

 

[trq]

session_register has long been deprecated.

[ZulfadlyAshBurn]

$_SESSION[];

 

session_register is a deprecated method thus is wont really be a good thing for the server.

Thank you ZulfadlyAshBurn

"Won’t really be a good thing for the server"

Means security issues or slow down the server?

 

 

[voip03]

Instead of this

<?
session_register(USER_NAME);
$_SESSION['USER_NAME']=$username;
?>

 

I can write the code like this?

<?
$_SESSION['USER_NAME']=$username;
?>

[ZulfadlyAshBurn]

there would be errors if your server were to upgrade to PHP 5.3> they might be errors.

 

 

// you will need session_start()
session_start();
$_SESSION['USER_NAME']=$username;

[voip03]

so the best way is

<?
$_SESSION['USER_NAME']=$username;
?>

thank you for your advice.

[ZulfadlyAshBurn]

yeap

[voip03]

This code works. I can echo it.

<?

$username='HelloJay';

$_SESSION['USER_NAME']=$username;

 

echo $_SESSION['USER_NAME'];

?>

BUT this code dose not ?

<?
$username='HelloJay';
$_SESSION['USER_NAME']=$username;

echo $_SESSION['USER_NAME'];
?>

[ZulfadlyAshBurn]

firstly use full <?php not the shortcut <?. and you never start the session

 

<?php

session_start();

$username='HelloJay';
$_SESSION['USER_NAME']=$username;

echo $_SESSION['USER_NAME'];
?>

<? is a bad practice. no prob. mark topic as solved its my honour to help people

session register

• session register returns Boolean type output
  
• session_register() is a php function used to register variables with the current session
  
• it will work only when register global is turned on in php.ini configuration file
  

 

$_SESSION[]

• $_session returns string
  
• $_SESSION[] is a super global array
  
• SESSION works in both case whether register_global is disabled or enabled

Actually. <?= is making something of a comeback ( not <? though) as a shortcut for <?php echo

 

In 5.4:

 

<?= is now always available regardless of the short_tags setting (Rasmus)

 

This is good news IMO as it helps tidy the code used in allot of frameworks default view scripts.

Actually.

What is the best way?

[trq]

It is still best to be avoided for now. It'll be a long time before 5.4 is the standard.

[voip03]

I take it this is the best method

<?php
echo “I’m a lumberjack.”;
echo “And I’m okay.”;
?>

thank you.
