Solr returns response in following JSON format.
{
"responseHeader":{
"status":0,
"QTime":2,
"params":{
"indent":"on",
"start":"0",
"q":"*:*",
"wt":"json",
"version":"2.2",
"rows":"10"}},
"response":{"numFound":3,"start":0,"docs":[
{
"student_id":"AB1001",
"student_name":[
"John"]
},
{
"student_id":"AB1002",
"student_name":[
"Joe"]
},
{
"student_id":"AB1003",
"student_name":[
"Lorem"]
}]
}}
What will be the simple way to read student_id, student_name using PHP?

Answer 1

Use $obj = json_decode($yourJSONString); to convert it to an object.
Then use foreach($obj->response->docs as $doc) to iterate over the "docs".
You can then access the fields using $doc->student_id and $doc->student_name[0].

Answer 2

PHP has a json_decode function that will allow you to turn a JSON string into an array:
$array = json_decode($json_string, true);
$student_id = $array['response']['docs'][0]['student_id'];
...
Of course, you might want to iterate through the list of students instead of accessing index 0.

Answer 3

$result = json_decode($result, true);
$result['response']['docs'][0]['student_id'] ...

Answer 4

Why not just use one of the PHP clients for Solr, or the PHP response writer? See http://wiki.apache.org/solr/SolPHP

Answer 5

$json_a = json_decode($string, TRUE);
$json_o = json_decode($string);
#array method
foreach($json_a['response']['docs'] as $students)
{
echo $students['student_id']." name is ".$students['student_name'][0];
echo "<br>";
}
#Object Method`enter code here`
foreach($json_o->response->docs as $sthudent_o)
{
echo $sthudent_o->student_id. " name is ".$sthudent_o->student_name[0];
echo "<br>";
}
