JSON string deserialized into an object/array method in PHP

This article mainly describes the JSON PHP, JSON string deserialization into an object/array method, has a certain reference value, now share to everyone, the need for friends can refer to

As shown below:

<?php//php parsing JSON information//json_decode (JSON string); $city = Array (' shandong ' = ' Jinan ', ' henan ' = ' zhengzhou ', ' Hebei ' = ' Shijiazhuang '); $jn _city = Json_encode ($city);//anti-coding json$fan_city = Json_decode ($jn _city,false);// The second parameter, FALSE, returns the object type, false to default Var_dump ($fan _city),//object (StdClass) #1 (3) {["Shandong"]=> string (5) "Jinan" ["Henan"]=> string (9) "Zhengzhou" ["Hebei"]=> string "Shijiazhuang"} echo "<br/>"; $fan _city = Json_deco De ($jn _city,true);//The second parameter true returns the array type Var_dump ($fan _city);//array (3) {["Shandong"]=> string (5) "Jinan" ["Henan "]=> string (9)" Zhengzhou "[" Hebei "]=> string ()" Shijiazhuang "}

Manually written JSON strings must be enclosed in single quotation marks to successfully deserialize an object/array:

<?php  //json Information Anti-coding  //different PHP versions, there is a problem with the "pure JSON string" parsing//The JSON string anti-encoding operation using double quotation marks becomes null//$jn = "{' name ': ' Tom ', ' age ' : ' A ', ' addr ': ' Beijing '}; $fan _jn = Json_decode ($jn, true); Var_dump ($fan _jn);//null  //The JSON string anti-encoding operation that is defined with single quotation marks succeeds $jn = ' {' name ': ' Tom ', ' Age ': ', ' ' addr ': ' Beijing '} '; $fan _ JN = Json_decode ($JN, true); Var_dump ($fan _jn);
