Read JSON Data Using PHP

Question

Solr returns response in following JSON format.

{
  \"responseHeader\":{
    \"status\":0,
    \"QTime\":2,
    \"params\":{
      \"indent\":\"on\",
      \         


        

Answer 1

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

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

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 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>";
}
