PHP - getting content of the POST request

Question

I have problem with getting the content. I don't know the names of the post variables so I can't do this using

 = $_Post['name']

because I don't know the "name". I want to catch all of the variables send by POST method. How can I get keys of the $_Post[] array and the values related with them?

Answer 1

Standard for-each:

foreach ($_POST as $key => $value)
{
  // ... Do what you want with $key and $value
}

Answer 2

$_POST is just a big array:

while(list($keys,$vars) = each($_POST)){ // do something. }

Answer 3

Just use a for each loop

foreach($_POST as $key => $value){
   echo "$key = $value";
}

Answer 4

for some quick debugging, you can also use

print_r ($_POST)

Answer 5

To get the keys:

array_keys($_POST);

Answer 6

Besides print_r($_POST); you could also use var_dump($_POST);, but most logical solution as mentioned earlier is foreach loop.

Answer 7

basically post request will be mapped to array. for debuging you can call

var_dump($_POST);

this code will list all array within post array.
