如何用爆键和值数组没有在PHP的foreach [英] How to implode array with key and value without foreach in PHP

问题描述

如果没有的foreach
我怎么可以把这样的数组

Without foreach, how can I turn an array like this

array("item1"=>"object1", "item2"=>"object2",......."item-n"=>"object-n");

像这样的字符串

item1='object1', item2='object2',.... item-n='object-n'

我想到了破灭（）了，但它并没有与它破灭的关键。

I thought about implode() already, but it doesn't implode the key with it.

如果的foreach有必要，是否有可能不能嵌套在foreach？

If foreach it necessary, is it possible to not nest the foreach?

编辑：我已经改变了字符串

EDIT2 / UPDATE：
这个问题在相当长的一段前问道。当时，我想在一行中写的一切，所以我会用三元运营商和巢建在赞成的foreach的函数调用。这是不是一个好的做法！写code，它是可读的，无论是简洁与否不管那么多了。

EDIT2/UPDATE: This question was asked quite a while ago. At that time, I wanted to write everything in one line so I would use ternary operators and nest built in function calls in favor of foreach. That was not a good practice! Write code that is readable, whether it is concise or not doesn't matter that much.

在这种情况下：（！即使所有的答案是伟大的），将在foreach在功能会比写一行代码更具可读性和模块化

In this case: putting the foreach in a function will be much more readable and modular than writing a one-liner(Even though all the answers are great!).

推荐答案

和另一种方式：

$input = array(
    'item1'  => 'object1',
    'item2'  => 'object2',
    'item-n' => 'object-n'
);

$output = implode(', ', array_map(
    function ($v, $k) {
        if(is_array($v)){
            return $k.'[]='.implode('&'.$k.'[]=', $v);
        }else{
            return $k.'='.$v;
        }
    }, 
    $input, 
    array_keys($input)
));

或

$output = implode(', ', array_map(
    function ($v, $k) { return sprintf("%s='%s'", $k, $v); },
    $input,
    array_keys($input)
));
