填充关联数组 [英] Populating associative arrays

问题描述

时有什么错 $数据[$关键] [$ VAL] = []; ，因为在本地主机上它的作品不错，但在服务器上它不（字preSS显示空白页，我注意到，它打破​​只在该行）

  $个月=阵列（'sijecanj'=＆GT;'Siječanj'，'veljaca'=＆GT;'Veljača'，'ozujak'=＆GT;'Ožujak'，'travanj = GT;'Travanj'...）;
$份=阵列（'Plodovi'，'Korijen'，'高良'，'Sjeme'）;$数据=阵列（）;
的foreach（$个月$关键=＆GT; $ VAL）{
    $数据[$关键] [$ VAL] = [];
    的foreach（$部分为$一部分）{
        如果（has_term（$一部分，$键））{
            array_push（$数据[$关键] [$ VAL]，$部分）;
        }
    }
 

}

我所试图做的是有每个月的数组，如果它与特定部分的一些价值观，同时有关的键值对了好几个月。 （我需要密钥塞从字preSS数据库和价值获取的数据将被呼应'），这样，最终我得到这样

  $数据= [
    Siječanj'=＆GT; ['Plodovi'，'Korijen']，
    Kolovoz'=＆GT; ['高良'，'Sjeme']
]
 

解决方案

这无关你的文本编辑器。它与你的PHP版本做。你的开发环境中运行PHP 5.4+和生产环境中运行PHP 5.3或以上这确实的不的支持短数组语法（即 [] ）这是在PHP 5.4引入的。

所以

  $数据[$关键] [$ VAL] = [];
 

要成为

  $数据[$关键] [$ VAL] =阵列（）;
 

成为向后兼容。

Is there something wrong with $data[$key][$val] = [];, because on localhost it works nice but on server it doesnt (Wordpress shows blank page, and I noticed that it breaks just on that line)

$months = array('sijecanj' => 'Siječanj', 'veljaca' => 'Veljača', 'ozujak' => 'Ožujak', 'travanj' => 'Travanj'...);
$parts = array('Plodovi' ,'Korijen', 'Kora', 'Sjeme'); 

$data = array();
foreach($months as $key => $val) {
    $data[$key][$val] = [];
    foreach($parts as $part) {
        if( has_term( $part, $key ) ) {
            array_push($data[$key][$val], $part);
        }   
    }

}

What I am trying to do is to have an array for each month if it has some values with specific parts, while also pertaining key-value pairs for months. (I need key as slug for fetching data from Wordpress database and value will be echoed'), so that in the end I get something like this

$data = [
    'Siječanj' => ['Plodovi', 'Korijen'],
    'Kolovoz' => ['Kora', 'Sjeme']
]

解决方案

This has nothing to do with your text editor. It has to do with your PHP versions. Your development environment is running PHP 5.4+ and your production environment is running PHP 5.3 or older which does not support short array syntax (i.e. []) which was introduced in PHP 5.4.

So

$data[$key][$val] = [];

needs to become

$data[$key][$val] = array();

to become backwards compatible.
