我想将三个数组合并在一起。所有这些数组都是完全相同的，只是内部有不同的数据，每个数组有50个项目，每个项目都有一个名为标签等的对象。
我的问题是，当我尝试将它们合并在一起然后将它们作为JSON回显时，我怎么得到不同的响应，而不是单独将它们作为JSON回显。
$tagArrays = array_merge($tags,$tags2,$tags3);
echo json_encode($tagArrays, JSON_PRETTY_PRINT);
给我不同的结果
echo json_encode($tags, JSON_PRETTY_PRINT);
echo json_encode($tags2, JSON_PRETTY_PRINT);
echo json_encode($tags3, JSON_PRETTY_PRINT);
当我说“不同的结果”时，我的意思是大不相同，似乎$ tags [i]没有被合并，而是因为他们使用相同的数据而被压扁。我希望它们合并类似于JSON_encoding它们单独工作的方式。
如果这有帮助，这就是数组的样子（缩短，想象每个数组50倍的项目对象，然后重新开始）

如何停止合并压缩阵列并将它们加在一起？
编辑：我的最终目标是让我能够使用while ($i < 150)（来自一个数组中的所有项目，而不是使用while ($i < 50)三次
答案 0 :(得分：1)
我在代码中没有看到任何内容......但这可以完成工作：
$result = [];
for($i = 0; $i < 50; $i++){
for($j = 1; $j <= 3; $j++){
$var = 'tags'.($j>1?$j:'');
$result[] = $$var;
}
}
json_encode($result, JSON_PRETTY_PRINT);
这会将$tags添加到$result然后$tags2再添加$tags3再添加50次
答案 1 :(得分：0)
我真的不喜欢回答我自己的问题，特别是对于这样一个简单的错误，但我遇到的问题是我误解了我想要做的事情。当@MarekJanoud让我清楚的时候，它允许我做更多的研究，发现array_merge_recursive允许我将所有数组合并为一个允许我使用数据而我原本想要的。 / p>
谢谢@MarekJanoud
