Parsing unknown POST Args in PHP

Question

I have an HTML form being populated by a table of customer requests. The user reviews each request, sets an operation, and submits. The operation gets set into a post arg as follow

$postArray = array_keys($_POST);

[1]=>Keep [2]=>Reject [3]=>Reject [4]=>Ignore ["item id"]=>"operation"

This is how I am parsing my Post args... it seems awkward, the unused $idx. I am new to PHP, is there a smoother way to do this?

$postArray = array_keys($_POST); 
foreach($postArray as $idx => $itemId) { 
 $operation = $_POST[$itemId];
 echo "$itemId $operation </br>";
 ...perform operation...
}

Answer 1

It looks like you may want to unset the 'item id' entry in your post array before you do the processing:

unset($_POST['item id']);

Then you can use foreach to loop over the key (idx) and value (operation).

foreach ($_POST as $idx => $operation)
{
 echo $idx . ' ' . $operation . '</br>';
 // perform operation.
}

The array_keys function was unnecessary because foreach can be used with associative arrays handling both their keys and values.

Answer 2

You dont need to grab the the keys separately.

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