How to get String value from json_decode in php

Question

My json-data is as follows -

[{"name": "ram"}]

What I want is the value of name in a variable e.g., $fname. I have tried -

<?php
$jsondata = '[{"name": "ram"}]';
//$obj = json_decode($jsondata);
$obj = json_decode($jsondata,true);
print_r($obj); // This line outputs as :- Array ( [0] => Array ( [name] => ram ) ) 
//What I need is value of key
print_r($obj['name']);
foreach ($obj as $k=>$v){
echo $v;
}
?>

But I am unable to get desired output.

echo $obj['name'];
?>

As your output indicates, your JSON string represents an array containing one object. As you know that you want a value contained within the first element, you can get it directly:

$jsondata = '[{"name": "ram"}]';
$obj = json_decode($jsondata, true);
$name = $obj[0]['name'];
echo $name;
