代码吧 这节课的  

<?php
$array_1 = array(); //一维
$array_2 = array(); //多维

$array_1['usrename'] = "ericwolf";
$array_1['age'] = 25;

$array_2['member']['username'] = "ericwolf";
$array_2['member']['age'] = 25;

$jsonObj1 = json_encode($array_1);
$jsonObj2 = json_encode($array_2);
echo $jsonObj1."</br>";
echo $jsonObj2."</br>";

print_r($array_1."     array1</br>");
print_r($array_2."     array2</br>");

$jsonStr = '{"key":"value","key1":"value"}';
$json2Array = json_decode($jsonStr,true);
print_r($json2Array);
?>

<?php

$array_1 = array(); //一维

$array_2 = array(); //多维

$array_1['usrename'] = "ericwolf";

$array_1['age'] = 25;

$array_2['member']['username'] = "ericwolf";

$array_2['member']['age'] = 25;

$jsonObj1 = json_encode($array_1);

$jsonObj2 = json_encode($array_2);

echo $jsonObj1."</br>";

echo $jsonObj2."</br>";

print_r($array_1."     array1</br>");

print_r($array_2."     array2</br>");

$jsonStr = '{"key":"value","key1":"value"}';

$json2Array = json_decode($jsonStr,true);

print_r($json2Array);

?>

json_encode解析中文会乱码，童鞋们请问怎么解决呀
