This is probably common sense to a lot of people but I spent close to two hours trying to figure
this out.
I had an array output that looked like this:
<?php
/*
Array
(
[0] => stdClass Object
(
[event_id] => 1
[form_name] => Long Beach 2012
[form_id] => longbeach2012
[registrations] => 1
)
[1] => stdClass Object
(
[event_id] => 2
[form_name] => Las Vegas 2013
[form_id] => lasvegas2013
[registrations] => 0
)
)
*/
?>
Inside of the array are objects so you could call a single value by doing something like:
<?php
$arr[0]->event_id; // returns 1
?>
So to be able to do a foreach through it do the following:
<?php
$results = array(); // The array we're working with
foreach( $results as $obj )
{
foreach( $obj as $key => $value )
{
echo $key; // returns event_id, form_name, etc.
echo $value; // returns 1, Long Beach 2012
}
}
?>
