I am trying to display single value from array of values.
If I use print_r($arr) it shows this values
{
"a": 14,
"b": 3,
"c": 61200,
"d": [
"2014-04-22 12:00:06",
"2014-04-23 12:00:06",
"2014-04-24 12:00:06"
]
}
But when I tried to use echo $arr->a and $arr['a'].
It shows illegal string offset 'a'.
How to get single value from array of values?
looks like json so need decode first with json_decode()
$d = '{"a":14,"b":3,"c":61200,"d":["2014-04-22 12:00:06","2014-04-23 12:00:06","2014-04-24 12:00:06"]}';
$j = json_decode($d);
echo '<pre>';
print_r($j);
echo $j->a;
Decode from JSON:
$v = json_decode('{
"a": 14,
"b": 3,
"c": 61200,
"d": [
"2014-04-22 12:00:06",
"2014-04-23 12:00:06",
"2014-04-24 12:00:06"
]
}');
echo $v->a;
More information would be useful. What version of PHP are using? Are you using a web engine (Apache, Nginx, etc) or just command line? Correct me if I'm wrong but I am assuming your using json_decode and making an it an object.
$obj = json_decode('{"a":14,"b":3,"c":61200,"d":["2014-04-22 12:00:06","2014-04-23 12:00:06","2014-04-24 12:00:06"]}');
echo "Result: " . $obj->a;
Result: 14
This worked just fine in PHP Versions 5.3, 5.4, 5.5
Try this
$arr = json_decode($arr);
echo $arr->a
The input looks like JSON - try the following to parse the JSON data:
$json_string = '{
"a": 14,
"b": 3,
"c": 61200,
"d": [
"2014-04-22 12:00:06",
"2014-04-23 12:00:06",
"2014-04-24 12:00:06"
]
}';
$vals = json_decode($json_string);
echo $vals->a;
