转换的MultiArray到SingleArray没有的foreach [英] Convert MultiArray to SingleArray without foreach

问题描述

如果我有一个数组，里面坐了一个单一的阵列。有没有办法推子数组值到父无需运行一个foreach？

例如，如果我有一个数组是这样的：

 阵列（[0] =＆GT;阵列（
               KEY1=＆GT; 值1
               KEY2=＆GT; VALUE2
                KEY3=＆GT; 值3
               ）
     ）;
 

和我想要将其降低到这一点：

 阵列（
    KEY1=＆GT; 值1
    KEY2=＆GT; VALUE2
    KEY3=＆GT; 值3
   ）;
 

是否有这样做没有一个foreach的一种方式？

目前我在做这样的：

  $ singleArr =阵列（）;
的foreach（$ multiArr为$ subArr）{
   $ singleArr = $ subArr;
}
 

解决方案

有关简单什么：

  $ singleArr = $ multiArr [0];
 

If I have an array, with a single array inside it. Is there a way push the child array values into the parent without having to run a foreach?

For example, if I have an array like this:

array( [0] => array(
               "key1" => "value1",
               "key2" => "value2",
                "key3" => "value3",
               )
     );

and I want to reduce it to this:

  array(
    "key1" => "value1",
    "key2" => "value2",
    "key3" => "value3",
   );

Is there a way of doing this without a foreach?

at the moment I'm doing this:

$singleArr = array();
foreach($multiArr as $subArr) {
   $singleArr = $subArr;
}

解决方案

What about simple:

$singleArr = $multiArr[0];
