getting all info in session post and get - php

Question

I want to display all the session , post , get information of my php page (.php) in the page. How can I do that?

Answer 1

Ok, everybody states the obvious, but they do not mention the security risk embedded in every solution.
I beg to differ, here is my alternative:
echo "<pre>";
echo htmlspecialchars(var_export($_POST, true), ENT_QUOTES);
echo htmlspecialchars(var_export($_GET, true), ENT_QUOTES);
echo htmlspecialchars(var_export($_SESSION, true), ENT_QUOTES);
echo "</pre>";
You probably do not think about an attacker putting malicious code into your session, but you never know.
To put it different:
header("Content-type: text/plain");
var_export($_POST);
var_export($_GET);
var_export($_SESSION);
will equally work well, but beware browsers trying to sniff the content.
Another method that prints two thirds of the stuff nicely:
phpinfo(INFO_VARIABLES);
And at last: Try the <plaintext> tag. It has no closing tag for obvious reasons, because it will end the interpretation of HTML in the browser, but after it was sent, you'll only have to care about printing plain text.
echo "<plaintext>";
var_export($_POST);
var_export($_GET);
var_export($_SESSION);
var_export has an advantage above var_dump and print_r: It prints valid PHP code that is able to recreate the variable. This is true 100% for any type but objects. Objects have to implement the magic static method __set_state to be able to be recreated.

Answer 2

Use the below code to print / var_dump the information
For Session Is Below
<?php var_dump($_SESSION); ?>
For Post Is Below
<?php var_dump($_POST); ?>
For Get Is Below
<?php var_dump($_GET); ?>

Answer 3

<?php print_r($_SESSION); ?>
<?php print_r($_POST); ?>
<?php print_r($_GET); ?>

Answer 4

Try this :
POST
foreach ($_POST as $key => $value) {
$postData = "POST Field " . htmlspecialchars($key) . " is " . htmlspecialchars($value) . "<br>";
}
GET
foreach ($_GET as $key => $value) {
$postData = "GET Field " . htmlspecialchars($key) . " is " . htmlspecialchars($value) . "<br>";
}
SESSION
foreach ($_SESSION as $key => $value) {
$postData = "SESSION Field " . htmlspecialchars($key) . " is " . htmlspecialchars($value) . "<br>";
}

Answer 5

I prefer var_dump() over print_r(), as it handles objects as well.
I also like to output <pre> tags around my dump, so its easier to read in a browser, so
echo "<pre>";
var_dump($_SESSION);
var_dump($_POST);
var_dump($_GET);
echo "</pre>";
