PHP Access JSON data
JSON data needs to converts to an array or an object before we can access them.
Example 1: JSON data and Object
- Convert JSON data to object, and access object values.
<?php
$my_name = '{"age":30,"address":"huntsville"}';
$my_profile = json_decode($my_name);
echo "My age is: " . $my_profile->age .
" address " . $my_profile->address;
?>
Output
My age is: 30 address huntsville
Example 2: JSON data and Associative array
- Convert JSON data to an associative array and access an associative array values.
<?php
$my_json_data = '{
"name":"paul",
"age":28,
"address":"Houston, Tx",
"jobtitle":"php developer",
"hometown":"huntsville"}';
$my_arry_data = json_decode($my_json_data, 1);
foreach ($my_arry_data as $k => $v) {
echo "{$k}=>{$v}<br/>";
}
?>
Output
name=>paul age=>28 address=>Houston, Tx jobtitle=>php developer hometown=>huntsville
Example 3: JSON data and object
- Convert JSON data to object and access object values.
<?php
$my_aj = '
{
"person":
[
{"name":"paul","age":30,"address":"huntsville"},

}';
// convert json to object
$my_obj = json_decode($my_aj);
echo $my_obj->person[0]->name; // paul
echo "<br/>";
echo $my_obj->person[0]->age; // 30
echo "<br/>";

echo "<br/>";
echo $my_obj->country[0]->name ; // japan
