Access the values in array php - php

Question

I am trying to access the values of an array.
Array ( [0] => stdClass Object ( [action_type] => comment [value] => 19074.125 ) [1] => stdClass Object ( [action_type] => like [value] => 2179.9 ) [2] => stdClass Object ( [action_type] => link_click [value] => 16.633202528886 ) [3] => stdClass Object ( [action_type] => offsite_conversion.fb_pixel_add_to_cart [value] => 451.45857988166 ) [4] => stdClass Object ( [action_type] => offsite_conversion.fb_pixel_complete_registration [value] => 897.60588235294 ) [5] => stdClass Object ( [action_type] => offsite_conversion.fb_pixel_initiate_checkout [value] => 1230.5887096774 ) [6] => stdClass Object ( [action_type] => offsite_conversion.fb_pixel_lead [value] => 372.17804878049 ) [7] => stdClass Object ( [action_type] => offsite_conversion.fb_pixel_purchase [value] => 2384.265625 ) [8] => stdClass Object ( [action_type] => offsite_conversion.fb_pixel_view_content [value] => 63.316597510373 ) [9] => stdClass Object ( [action_type] => post [value] => 8477.3888888889 ) [10] => stdClass Object ( [action_type] => post_like [value] => 193.15569620253 ) [11] => stdClass Object ( [action_type] => unlike [value] => 76296.5 ) [12] => stdClass Object ( [action_type] => page_engagement [value] => 15.168290258449 ) [13] => stdClass Object ( [action_type] => post_engagement [value] => 15.274574574575 ) [14] => stdClass Object ( [action_type] => offsite_conversion [value] => 43.39960182025 ) )
I need to access the value of [action_type] => offsite_conversion.fb_pixel_purchase [value] => 2384.265625 , how to get the value of only offsite_conversion.fb_pixel_purchase ??
these values comes from the foreach loop.
$r = $i->cost_per_action_type;
foreach($r as $key => $value){
echo $key["action_type"];
}
the array you are seeing is the print_r($x).

Answer 1

If you want to use the result as an array and not as object, use:
//will return an associative array
$x = json_decode($j, true);
In your code $x is an object, not array, so that foreach is incorrect. You should work on your code and give some reasons for witch you encoded an array just to decode it and try to use it like an array not as object.
You should change the Object to array if you are using the array and got rid of the encode.
You can do what #Chay22 did in the example as array:
foreach($r as $val){
if ($val[action_type] == 'offsite_conversion.fb_pixel_purchase') {
echo $val[value];
}
}

Answer 2

You're trying to treat object as array which doesn't simply working. Use arrow operator -> instead to get object value.
foreach($r as $val){
echo $val->action_type;
}
In case you're really wanted it to be an array, make sure to implement interfaces that gives ability to treat object as an array ArrayAccess, Countable, etc. You can also extends ArrayObject class, too.
And, according to your comment
foreach($r as $val){
if ($val->action_type == 'offsite_conversion.fb_pixel_purchase') {
echo $val->value;
}
}
