如何将上面的数组转换为下面的数组。上面的数组里面有9个数组。他们掌握了ID并在内部排名。我想让他们成为一个字符串。 masteryid XX排名++ masteryid XX排名....多维数组将数组转换为字符串

Array 
( 
    [0] => 6111 xx 5 ++ 6122 xx 1 ++ 6131 xx 5 ++ 6142 xx 1 .... 
    [1] => 6114 xx 5 ++ 6123 xx 1 ++ 6131 xx 5 ++ 6142 xx 1 .... 
    .... 
    [9] => 6221 xx 5 ++ 6223 xx 1 ++ 6231 xx 5 ++ .... 
)

我坚持这个代码，我试图做到这一点约5小时我不能做，所以我来到了这里。

你真的应该学会等待答案。没有冒犯_Youcef Moulahoum_但是这可能就做最坏的方式之一。如果有任何解释，我会选择_Matt Raines_。 – AbraCadaver

如果你再问类似的问题，请使用'var_export'而不是'print_r'包括样本数据。 'var_export'的输出是PHP代码，所以我们可以将它复制并粘贴到脚本中进行测试。 –

@MattRaines哦，我不知道这病该用下一次感谢信息 – Heptagon

试试这个：

$output = array(); 

foreach($array as $value) 
{ 
    $s = ""; 
    foreach($value as $v) 
     $s .= $v['masteryId'].' xx '.$v['rank'].' ++ '; 

    $output[] = rtrim($s,' ++ '); 
}

我希望这将帮助你。

非常感谢！ :)你能稍微解释一下这段代码吗？我会在2分钟内将此答案标记为正确。 – Heptagon

魔术单行：

array_walk($array,function(&$a){$a=array_reduce($a,function($b,$c){return($b?"$b ++ ":"")."$c[masteryId] xx $c[rank]";},"");});

这要求外阵列中的每个元素的匿名函数。因为在$a之前的&对该元素的引用被传递，并且我们可以在该函数内对其进行修改。

然后，该函数通过附加"$c[masteryId] xx $c[rank]"到先前减少的结果减少反过来每个元素为一个字符串。前面的输出，随后" ++ "如果它存在只是前缀（即它是不是在子阵列第一项目）。

这是多一点清晰，具有一定的空白和一些潜在的更清晰的变量名:)

array_walk($array, function(&$subarray){ 
    $subarray = array_reduce($subarray, function($carry, $item){ 
     return ($carry ? "$carry ++ " : "") . "$item[masteryId] xx $item[rank]"; 
    }, ""); 
});
