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。而且他们掌握了并且在内部排名。我想让它们成为一个字符串。 masteryid xx rank ++ masteryid xx rank ....
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 ++ ....
)
我坚持使用这个代码，我试着这个约5个小时，我无法做到这一点，所以我来到这里。

试试这个：
$output = array();
foreach($array as $value)
{
$s = "";
foreach($value as $v)
$s .= $v['masteryId'].' xx '.$v['rank'].' ++ ';
$output[] = rtrim($s,' ++ ');
}
我希望这会对你有帮助。

Magic one-liner：
array_walk($array,function(&$a){$a=array_reduce($a,function($b,$c){return($b?"$b ++ ":"")."$c[masteryId] xx $c[rank]";},"");});
这为外部数组中的每个元素调用一个匿名函数。由于&之前$a传递了对元素的引用，我们可以在函数内修改它。
然后，该函数通过将"$c[masteryId] xx $c[rank]"附加到前一个减少的结果，将每个元素依次减少为一个字符串。之前的输出，后跟" ++ "仅在它存在时才被添加（即它不是子数组中的第一个项）。
这里有一些更清晰，有一些空格和一些可能更清晰的变量名称：）
array_walk($array, function(&$subarray){
$subarray = array_reduce($subarray, function($carry, $item){
return ($carry ? "$carry ++ " : "") . "$item[masteryId] xx $item[rank]";
}, "");
});
