PHP somo la 85: Jinsi ya utengeneza json data kwa utumia php

JSON kwenye PHP

Ili iweze kutengeneza data za json kwenye php tutatumia function ya json_encode() na mara nyingi data ambazo hutengenezewa json file kwenye php ni object na array. Ijapokuwa unaweza kutengeneza kwa data nyinginezo kama variable za kawaida.

1. Kwa kutumia variable za kawaida

Mfano nna varable hiizi

$jian = 'juma';

$umr = 30;

$ndoa = true;

Kama unataka kutengeneza json kwa varable mojawapo hapo unaweza ufanya hivi

Mfano:

<?php

$jiana = 'juma';

//encode variable

$ecoded_jina = json_encode($jiana);

//output

echo $ecoded_jina;

?>

Hii utatuletea 

"juma"

Ama unaweza pia kutengeneza data za json moja kwa moja kwenye code zako za php kisha uta zi encode.

Mfano

<?php

$jian = 'juma';

$umr = 30;

$ndoa = true;

// Manually create a JSON string

$jsonData = '{' .

   '"jian": "' . $jian . '",' .

   '}';

echo $jsonData;

?>

Hapo {"jian": "juma",}

Sasa utaona hapo kazi imekuwa ngumu ya kutengeneza json file. Kurahisisha kazi hiyo tunakwenda kuweka data zetu kwenye array ikli iwe rahisi kutengeneza json data.

<?php

$jian = 'juma';

$umr = 30;

$ndoa = true;

$data = array(

   "jian" => $jian,

   "umr" => $umr,

   "ndoa" => $ndoa

);

$jsonData = json_encode($data);

echo $jsonData;

?>

Kwa kutumia object:

Kama tulivyoona kwenye mfano wa kwanza basi tunaweza kutengeneza json data kwa kutumia OOP. Hapa tutatumia Object

<?php

// Create a simple class

class Person {

   public $name;

   public $age;

   public $isStudent;

   public function __construct($name, $age, $isStudent) {

       $this->name = $name;

       $this->age = $age;

       $this->isStudent = $isStudent;

   }

}

// Create an object

$person = new Person("Jane Doe", 25, true);

// Convert the objec...
