Example 1: string json format to object in php
<?php
$someJSON = '[{"name":"Jonathan Suh","gender":"male"},{"name":"William Philbin","gender":"male"},{"name":"Allison McKinnery","gender":"female"}]';
$someArray = json_decode($someJSON, true);
print_r($someArray);
echo $someArray[0]["name"];
$someObject = json_decode($someJSON);
print_r($someObject);
echo $someObject[0]->name;
?>
Example 2: php convert array to json object
$myArr = array("apple", "banana", "mango", "jackfruit");
$toJSON = json_encode($myArr);
echo $toJSON;
Example 3: php json_decode
$personJSON = '{"name":"Johny Carson","title":"CTO"}';
$person = json_decode($personJSON);
echo $person->name;
Example 4: convert object to array php
<?php
class sample {
var $var1;
var $var2;
function __construct( $par1, $par2 )
{
$this->var1 = $par1;
$this->var2 = $par2;
}
}
$myObj = new sample(1000, "second");
echo "Before conversion: \n";
var_dump($myObj);
$myArray = json_decode(json_encode($myObj), true);
echo "After conversion: \n";
var_dump($myArray);
?>
Output:
Before conversion:
object(sample)#1 (2) {
["var1"]=>
int(1000)
["var2"]=>
string(6) "second"
}
After conversion:
array(2) {
["var1"]=>
int(1000)
["var2"]=>
string(6) "second"
}
Example 5: php json encode
$person = array(
"name" => "Johny Carson",
"title" => "CTO"
);
$personJSON=json_encode($person);
Example 6: json_encode json_decode php examples
json_encode used when PHP retrieve data and convert Array() to [] !!!!
$arr = array('a' => 1, 'b' => 2, 'c' => 3, 'd' => 4, 'e' => 5);
echo json_encode($arr);
{"a":1,"b":2,"c":3,"d":4,"e":5}
access from js file data.a, data.b,data.c...
----------------------------------------------
$json = '{"a":1,"b":2,"c":3,"d":4,"e":5}';
json_decode($json, true);
array(5) {
["a"] => int(1)
["b"] => int(2)
["c"] => int(3)
["d"] => int(4)
["e"] => int(5)
}
