How can php handle json strings

How can php handle json strings?

Code example:

<?php
$json = &#39;{"a":1,"b":2,"c":3,"d":4,"e":5}&#39;;
var_dump(json_decode($json));
｝

The output is

object(stdClass)#1 (5) {
["a"] => int(1)
["b"] => int(2)
["c"] => int(3)
["d"] => int(4)
["e"] => int(5)
}

php processing json string

<?php
$json = &#39;{"a":1,"b":2,"c":3,"d":4,"e":5}&#39;;
$jsonArr = json_decode($json, TRUE);
extract($jsonArr); //数组中将变量导入到以当前符号表
echo "a=$a;b=$b;c=$c;d=$d;e=$e;";
?>

Also The resulting object can also be traversed just like an array.

<?php
$json = &#39;{"a":1,"b":2,"c":3,"d":4,"e":5}&#39;;
$jsonObj = json_decode($json);
foreach($jsonObj as $jk=>$jv) {
    $$jk = $jv;
}
echo "a=$a;b=$b;c=$c;d=$d;e=$e;";
//也可得到相同的结果
?>

In addition, the value of the json object obtained through json_decode can also be obtained through "$jsonObj->a".
