my class in php contains an array -> mysql_fields. How do i go about extracting the info from the array?

giving a print_r($sub_details->mysql_fields) works as expected while,

but foreach($sub_details->mysql_fields as $key -> $value)

echo $key."->".$value;

doesnt work.

How do i got about iterating through the arrary?

it seems that if i ask it to echo explicitly like

$sub_details->mysql_fields it works but if i use $sub_details->mysql_fields[0] it doesnt.


With a foreach, $key is the key of the array and obviously, $value is the value so for

$array = array('key1' => 'value1', 'key2' => 'value2');

foreach will act like this

foreach ($array as $key => $value) {
  echo $key . '=' . $value; // key1 = value1, etc.
