[SOLVED] Array problem

[bpgillett]

hi.  echoing a string in my array from $_POST by numeric position returns nothing; however, referencing it by variable name works.  is there a problem referencing an array created from $_POST by numeric position?  if so, any way around this?  thanks.

works:

$post = $_POST;
echo $post['q1'];

doesn't work:

$post = $_POST;
echo $post[0];

surely

$post = $_POST;

should be something like

$post = $_POST['q1'];

$_POST is an associative array whose keys are the names of form fields. If you want to process it as an indexed array you can

$post = array_values($_POST);

 

However, if the only reason to do this is to loop through all the values then you can use

 

foreach ($_POST as $value) {
    echo $value;
}

thanks...i feel a little silly.  i'm actually manipulating the keys which are dynamically named from another page, so i have to reference them by there numeric position in an indexed array.  thanks again.
