解析错误：语法错误，意外的 '['，期待 ')' php

Question

I am creating a custom shipping method for opencart, however i am stuck on the catalog model file, which is for PHP 5.4+ , but how do i make it working with PHP 5.3 as Opencart Requirement is start from PHP 5.3

    $languages = $this->language->get('code');
    $quote_data = array();
    $quote_data['items'] = array(
        'code'         => 'items.items',
        'title'        => $this->config->get('items_shipping_description')[$languages],
        'cost'         => $this->config->get('items_cost'),
        'tax_class_id' => $this->config->get('items_tax_class_id'),
        'text'         => $this->currency->format($this->tax->calculate($items_cost, $this->config->get('items_tax_class_id'), $this->config->get('config_tax')))
    );

this line working fine with PHP 5.4+ but not PHP 5.3

'title'=> $this->config->get('items_shipping_description')[$languages],

I get an error for PHP 5.3 which is

Parse error: syntax error, unexpected '[', expecting ')' in ...

I've also read many duplicate question and tried many different way to make this working with no luck! please help, thank you!

Answer 1

Just assign it to variable: $description = $this->config->get('items_shipping_description') And then use:

$quote_data['items'] = array(
    'code'         => 'items.items',
    'title'        => $description[$languages]
    'cost'         => $this->config->get('items_cost'),
    'tax_class_id' => $this->config->get('items_tax_class_id'),
    'text'         => $this->currency->format($this->tax->calculate($items_cost, $this->config->get('items_tax_class_id'), $this->config->get('config_tax')))
);

Answer 2

$this->config->get('items_shipping_description')[$languages]

This is function array dereferencing and was only added in php 5.4

To make it work with php 5.3 you will need to assign that return value to a variable and then use that.

$items = $this->config->get('items_shipping_description');
$items[$languages];

Answer 3

Try this,

$desc = $this->config->get('items_shipping_description');

And

'title'        => $desc[$languages],
