数组的串行化与反串行化

[php] view plain copy

 

 print?

<?php
    $arr = array("name"=>"zhangshan","age"=>10,"sex"=>"nan");

    //串行化,个人理解串行化就是把数组，文本等变成字符串，方便在数据库中存储
    $str = json_encode($arr);

    //反串行化,第二个参数true反串行化为数组；
    $parr = json_decode($str,true);

    var_dump($parr);
    echo $parr['name'];
?>
