本文实例讲述了php json相关函数用法。分享给大家供大家参考，具体如下：
函数列表：
| 函数 | 描述 |
|---|---|
| json_encode | 对变量进行json编码 |
| json_decode | 对json格式的字符串进行解码，转换为php变量 |
| json_last_error | 返回最后发生的错误 |
For example 1: json_encode
|
1
2
|
$arr=array("A"=>"a","B"=>"b","C"=>"c","D"=>"d");echo json_encode($arr); |
output:
|
1
|
{"A":"a","B":"b","C":"c","D":"d"} |
For example 2: json_decode
|
1
2
3
|
$arr='{"A":"a","B":"b","C":"c","D":"d"}';var_dump(json_decode($arr));var_dump(json_decode($arr,true)); |
output:
|

object(stdClass)[1] public 'A' => string 'a' (length=1) public 'B' => string 'b' (length=1) public 'C' => string 'c' (length=1) public 'D' => string 'd' (length=1)array (size=4) 'A' => string 'a' (length=1) 'B' => string 'b' (length=1) 'C' => string 'c' (length=1) 'D' => string 'd' (length=1) |
希望本文所述对大家PHP程序设计有所帮助。
