`{
"student": [{
"name": "Alice",
"rno": "187654"
}]
}`
I am trying to get the value of rno using PHP code
`$data = json_decode($json, true);
foreach ($data as $item) {
$name = $item['name'] ;
$number= $item['rno'] ;
}`
@Sahil Gulati's code is more prefect and right way to parse the json in php
here is an other way to parse the json data in php
<?php
$data = json_decode($json, true);
foreach ($data as $item) {
foreach ($item as $val) {
echo $name = $val['name'];
echo $number = $val['rno'];
}
}
?>
the above code that i have shared you can understand easily. but after learning that how to parse json data in php you should use @Sahil Gulati's mathod.
Change this to:
foreach ($data as $item)
This:
foreach ($data["student"] as $item)
PHP code:
<?php
ini_set('display_errors', 1);
$data = json_decode($json, true);
foreach ($data["student"] as $item)
{
$name = $item['name'];
$number = $item['rno'];
}
You should take a closer look at the structure of the json encoded data. That helps to implement a clean iteration:
<?php
$input = <<<JSON
{
"student": [{
"name": "Alice",
"rno": "187654"
}]
}
JSON;
$data = json_decode($input);
$output = [];
array_walk($data->student, function($entry) use (&$output) {
$output[] = $entry->rno;
});
print_r($output);
The output of above code obviously is:
Array
(
[0] => 187654
)
The output format has been chosen as an array, since the json structure suggests that multiple students can be contained.
If you are only directly interested in the rno property of the first entry in the student array, then you can access it directly:
<?php
$input = <<<JSON
{
"student": [{
"name": "Alice",
"rno": "187654"
}]
}
JSON;
$data = json_decode($input);
var_dump($data->student[0]->rno);
The output of that variant obviously is:
string(6) "187654"
