How to grab all variables in a post (PHP)

Question

How to grab all variables in a post (PHP)? I don\'t want to deal with $_POST[\'var1\']; $_POST[\'var2\']; $_POST[\'var3\']; ... I want to echo all of them in on

Answer 1

If you want the POST values as variables in your script, you can use the extract function, e.g.

extract ( $_GET );

or

extract ( $_GET, EXTR_IF_EXISTS );

There are several flags you can use (check the manual); this one restricts extraction to variables already defined.

You can also use the import_request_variables function.

Answer 2

Use this function in a loop. extract ( $_GET );

Answer 3

echo '<pre>'; 
print_r($_POST); 
echo '</pre>';

Answer 4

If you really just want to print them, you could do something like:

print_r($_POST);

Alternatively, you could interact with them individually doing something like:

foreach ($_POST as $key => $value) {
    //do something
    echo $key . ' has the value of ' . $value;
}

but whatever you do.. please filter the input. SQL Injection gives everyone sleepless nights.

Answer 5

Use:

var_dump($_POST);
