序列化二叉树

Serializing is a nice way to get a string out of more complicated data structure. It's probably mostly used to sting-alize array data, although you can serialize scalar data as well.

序列化是一种从更复杂的数据结构中获取字符串的好方法。 尽管您也可以序列化标量数据，但它可能主要用于数组数据的精简处理。

The result of the serialization is no nature wonder, it's just a string that describes what is serialized and a value of the serialized ... thing.

序列化的结果自然不奇怪，它只是一个描述序列化内容和序列化...值的字符串。

The cert guide explains it all very well, I think just maybe an example of how something looks when it's serialized would have been nice. Otherwise the serialization may sound scary and mysterious.

证书指南对此进行了很好的解释，我认为也许只是一个序列化后的外观示例。 否则，序列化听起来可能令人恐惧和神秘。

Here's an example: < ?php $s = 'PHP'; echo serialize($s); ?> This prints: s:3:"PHP"; Which means:

这是一个示例：<？php $ s ='PHP'; 回声序列化($ s); ？>打印： s:3:"PHP"; 意思是：

• 's' is a string, the type of the serialized var
  's'是一个字符串，是序列化var的类型
• '3' is the length
  长度为“ 3”
• 'PHP' is the value
  “ PHP”就是价值
• ';' is a delimiter
  ';' 是定界符

A slightly more complicated example - serializing an array:

稍微复杂一点的示例-序列化数组：

< ?php $ar = array('PHP','key'=>'serialize'); echo serialize($ar); ?> The result is: a:2:{i:0;s:3:"PHP";s:3:"key";s:9:"serialize";}

<？php $ ar = array('PHP'，'key'=>'serialize'); 回声序列化($ ar); ？>结果是： a:2:{i:0;s:3:"PHP";s:3:"key";s:9:"serialize";}

• 'a' means an array
  'a'表示数组
• 'i' as in integer
  'i'为整数
• 'i:0' is the integer key of the first element of the array, remember when you don't specify a key, PHP assigns one
  “ i：0”是数组第一个元素的整数键，请记住，当您不指定键时，PHP会分配一个
