Associative array always output as object: {“foo”:”bar”,”baz”:”long”}
Associative array always output as object: {“foo”:”bar”,”baz”:”long”}

JSON_HEX_AMP, JSON_HEX_APOS, JSON_NUMERIC_CHECK,
JSON_PRETTY_金沙糖果派对网站app,PRINT, JSON_UNESCAPED_SLASHES, JSON_FORCE_OBJECT,
JSON_UNESCAPED_UNICODE.

结果:

上述例程会输出:

var_dump(json_decode($json));
var_dump(json_decode($json, true));
?>

$json = '{"a":1,"b":2,"c":3,"d":4,"e":5}'; 
var_dump(json_decode($json));

能够观望json_decode($data,true卡塔尔国输出的一个关乎数组,由此可以见到json_decode($data)输出的是指标,而json_decode(“$arr”,true卡塔尔是把它逼迫生成PHP关联数组.

json_encode — 对变量举行 JSON 编码

assoc
当该参数为 TRUE 时,将回来 array 而非 object 。

能够看见json_decode($data,trueState of Qatar输出的二个事关数组,由此可以见到json_decode($data)输出的是目的,而json_decode(“$arr”,true卡塔尔国是把它抑遏生成PHP关联数组.

json_encode

Empty array output as array: []
Empty array output as object: {}

结果为:

代码如下:

Report a bug 更新日志
版本 说明
5.4.0 options 参数扩展常量: JSON_PRETTY_PRINT,
JSON_UNESCAPED_SLASHES, 和 JSON_UNESCAPED_UNICODE。
5.3.3 options 参数增添常量:JSON_NUMERIC_CHECK。
5.3.0 增加 options 参数.

接连数组

[2]=>
string(3) “baz”
[3]=>

}
string(27) “[“foo”,”bar”,”baz”,”blong”]”

能够观察json_encode()和json_decode(卡塔尔是编写翻译和反编写翻译进程,注意json只选取utf-8编码的字符,所以json_encode(卡塔尔的参数必需是utf-8编码,不然会得到空字符或许null。

assoc
当该参数为 TRUE 时,将回到 array 而非 object 。

echo json_decode($data,true);

**2.json_encode()

[“b”] => int(2)
[“c”] => int(3)
[“d”] => int(4)

Example #3 三番五次与非延续数组示例

代码如下:

<?php 
echo "连续数组".PHP_EOL; 
$sequential = array("foo", "bar", "baz", "blong"); 
var_dump( 
$sequential, 
json_encode($sequential) 
); 

echo PHP_EOL."非连续数组".PHP_EOL; 
$nonsequential = array(1=>"foo", 2=>"bar", 3=>"baz", 4=>"blong"); 
var_dump( 
$nonsequential, 
json_encode($nonsequential) 
); 

echo PHP_EOL."删除一个连续数组值的方式产生的非连续数组".PHP_EOL; 
unset($sequential[1]); 
var_dump( 
$sequential, 
json_encode($sequential) 
); 
?>

$obj->Name= ‘a1′;$obj->Number =’123’;
$obj->Contno= ‘000’;
echo json_encode($obj);

以上例程会输出:

{“a”:1,”b”:2,”c”:3,”d”:4,”e”:5}
