Within available_options I have somehow stripped out Express when I just wanted to keep one of them?
The array looks like this
["options"]=>
array(9) {
[0]=>
array(8) {
["id"]=>
string(2) "79"
["product_id"]=>
string(2) "15"

}
}
}

["option_price"]=>
string(5) "0.000"
}
}
}
[1]=>
array(6) {
["id"]=>
string(3) "223"
["product_options_base_id"]=>
string(2) "80"
["option_id"]=>
string(2) "12"
["option_data_id"]=>

["name"]=>
string(7) "Express"
["sku"]=>
string(3) "EXP"
["user_value"]=>
string(1) "1"
["sequence"]=>
string(4) "9999"
["status"]=>
string(1) "1"
["option_price"]=>
string(6) "25.000"
}
}
}
and my code goes like this
foreach($this->_data as &$data) {
foreach($data['options'] as &$option) {
$option['available_options'] = array_unique($option['available_options']);
}
}
It's working apart from it's stripped out the duplicates rather than showing them once?
array_unique does not work recursively, you need to go inside your array to apply it on option_data directly.
foreach($this->_data as &$data) {
foreach ($data['options'] as &$option) {
foreach ($option['available_options'] as &$available_option) {
foreach ($available_option['option_data'] as &$option_data) {
$option_data = array_unique($option_data);
}
}
}
}
This way, the last option_data looks like
'option_data' => [
[
'id' => '1',
'admin_name' => 'Express',
'sku' => 'EXP',
'sequence' => '9999',
'option_price' => '25.000'
]
]
But as you can see, the value Express only appear once, but user_value and status are removed too, because there value is 1, like id.
