这是我第一次面对，那var_dumping数组的json_encode生成布尔值。json_encode（）返回false
我有一个数组是由unserialization产生的。我var_dumped它，并确保它是一个有效的数组。结果如下所示。这只是一个部分，而不是整个调试视图。
array (size=3)
'id' => string 'asco-power-technologies-l-p' (length=27)
'name' => string 'asco-power-technologies-l-p' (length=27)
'children' =>
array (size=2)
0 =>
array (size=4)
'id' => string 'apl-logistics' (length=13)
'name' => string 'APL LOGISTICS' (length=13)
'data' =>
array (size=2)
'band' => string 'ASCO POWER TECHNOLOGIES ,L.P.' (length=29)
'relation' => string 'Buyer of band' (length=13)
'children' =>
array (size=11)
0 => &
array (size=3)
'id' => string 'trisa-ag' (length=8)
'name' => string 'TRISA AG' (length=8)
'data' =>
array (size=2)
'band' => string 'APL LOGISTICS' (length=13)
'relation' => string 'Buyer of band' (length=13)
1 => &
array (size=3)
'id' => string 'colgate-sanxiao-co-ltd' (length=22)
'name' => string 'COLGATE SANXIAO CO LTD' (length=22)
'data' =>
array (size=2)
'band' => string 'APL LOGISTICS' (length=13)
'relation' => string 'Buyer of band' (length=13)
.....
Aterwards i相最大深度= 3 json_encode它。请注意，我使用PHP 5.5并在Apache 2.4上运行，因此它支持json_encode（）上的深度参数。这就是我正在做的。
$array = unserialize($serial);
var_dump($array);
$json = json_encode($array, JSON_PRETTY_PRINT, 3);
var_dump($json);
最后我得到$array var_dumped正确和$json用假布尔值结果var_dumped。它出什么问题了？是否由于早期的PHP版本，不正确的var_dump会导致false布尔值？有没有人遇到过这个？
UPDATE：
这是连载的字符串。整个字符串太多，所以我只粘贴一块。

谢谢！你的问题帮助了我！在我的情况下，json_encode由于一个变量的编码而返回false ...我需要在执行json_encode之前对变量执行utf8_encode ...现在它起作用了！问候 –
