I want to change id_question with in_subject every time.
foreach ($questions_array as $key => $row){
$subject_sort[$key] = $row['id_subject'];
$question_pattern_sort[$key] = $row['id_question_pattern'];
}
array_multisort($question_pattern_sort, SORT_ASC, $subject_sort, SORT_ASC, $questions_array);
If I understand your question correctly, what you can do is loop through your array and set id_question = id_subject for each element of the array.
Like so:
foreach($questions_array['questions'] as $key=>$value){
$questions_array['questions'][$key]['id_question'] = $questions_array['questions'][$key]['id_subject'];
}
To sort by id_subject then id_question_pattern, I can recommend one of two approaches (depending on your php version).
The spaceship operator with usort(): (Demo)
usort($array["questions"],
function($a, $b){
return [$a['id_subject'], $a['id_question_pattern']] <=> [$b['id_subject'], $b['id_question_pattern']];
}
);
or with array_multisort() (Demo)
array_multisort(array_column($array["questions"], "id_subject"), SORT_ASC, array_column($array["questions"], "id_question_pattern"), SORT_ASC, $array["questions"]);
Take care to realize that you are wanting to sort within the questions subarray.

PHP code:

$json['loan']['fu']; // This works !
foreach($json['loan']['member'] as $item) {
$name = $item['name']; // This works !
foreach($json['loan']['member']['bank'] as $bank_item) { // THIS DOES NOT WORKS!
}
}
The last foreach loop gives out en error saying:
Notice: Undefined index: bank
Are there any clues as to what might be causing the issue, or is there some improved way of parsing the same JSON, that would be very helpful.
Your json parsing is fine. your accessing is missing index.
As the "bank" is inside an array of "member" you should access as $json['loan']['member'][0]['bank'] (the 0 is hard coded - you can switch for 1 also).
If you use for then you should do:
foreach($json['loan']['member'] as $item) {
$name = $item['name']; // This works !
foreach($item['bank'] as $bank_item) { // use $item
}
}
Use only a single foreach() and get the bank element value. If you further need to loop on bank element then you can use another foreach()
$json = json_decode($content, true);
foreach($json['loan']['member'] as $item) {
print_r($item['bank']);
foreach($item['bank'] as $bank_item) {
echo $bank_item;
}
}
DEMO: https://3v4l.org/qB8mV
You have missed that member is also multidimensional array
$json = json_decode($content, true);
/*
echo "<pre>";
print_r($json);
echo "</pre>";*/
foreach($json['loan']['member'] as $item => $value) {
$name = $value['name']; // This works !
foreach($json['loan']['member'][$item]['bank'] as $bank_item) { // THIS DOES NOT WORKS!
print_r($bank_item);
}
}
You can use array_walk_recursive() function also
$json = json_decode($content, true);
$i=0;
foreach($json['loan']['member'] as $item) {
array_walk_recursive($json['loan']['member'][$i]['bank'], function($value,$key) {
echo $key.' :'.$value ." \n";
});
$i++;
}

How can i parse the product details from json
You can use json decode function of php to make object then fetch data from object.
$data = 'write your json response here';
$return = json_decode($data);
print_r($return);
echo $return->result;
I am trying to encode the data in below JSON format. Not able to add the category array inside the categories. Scratching my head for long.. can anyone help me on this?
Desired Output:
{
"chart": {
"caption": "Product-wise Quarterly Revenue vs. Profit %",
"subCaption": "Harry's SuperMart - Last Year",
"xAxisname": "Quarter",
"pYAxisName": "Sales",
"sYAxisName": "Profit %",

},

{
"category": [

},
{
"label": "Q2"
},
{
"label": "Q3"
},
{
"label": "Q4"
}
]
}
]
}
My PHP code:
$arrData = array(
"chart" => array(
"caption"=> "Product-wise Quarterly Revenue vs. Profit %",
"subCaption"=> "Harry's SuperMart - Last Year",
"xAxisname"=> "Quarter",
"pYAxisName"=> "Sales",
"sYAxisName"=> "Profit %",
"numberPrefix"=> "$",

"showAlternateHGridColor"=> "0",
"subcaptionFontBold"=> "0",

)
);
$arrData["categories"] = array();
$arrData["category"] = array();
//array_push($arrData["categories"],array( $arrData["category"]));
//array_push($arrData["categories"],array( $arrData["category"]));
array_push($arrData["category"], array(
"label" => "Q1",
));
array_push($arrData["category"], array(
"label" => "Q2",
));
$json_string = json_encode($arrData, JSON_PRETTY_PRINT);
echo $json_string;
}
PHP output:
{
"chart": {
"caption": "Product-wise Quarterly Revenue vs. Profit %",
"subCaption": "Harry's SuperMart - Last Year",
"xAxisname": "Quarter",
"pYAxisName": "Sales",

},
"categories": [
],
"category": [
{
"label": "Q1"
},
{
"label": "Q2"
}
]
}
for ($i = 1; $i <= 4; $i++) {
$arrData['categories'][0]['category'] []= ["label" => "Q{$i}"];
}
By the way, you should use []= instead of array_push, because in that way there is no overhead of calling a function.
I am trying to read posts under each category as shown below. There are multiple categories with id "4", "3", "2", "1". Only for category "1" there is a post available.
foreach ($wp_categories as $wp_category) {
$id = $wp_category->term_taxonomy_id;
//if($id == "1") {
$posts = $json_api->introspector->get_posts(array(
'cat' => $id
));
//}
$result[] = $posts;
}
return $result;
In the above code if I just uncomment the if condition, I am getting the posts in the result array. But if this is commented I am not getting the posts in result.
I am new to PHP and above condition is not making any sense. It would be of great help if someone could explain why having the if condition is making the post available in the result.
dumping $wp_categories below

"term_order": "2",

"taxonomy": "category",

"parent": "0",
"count": "0"
},
"2": {
"term_id": "3",
"name": "Category 3",
"slug": "category3",
"term_group": "0",
"term_order": "3",
"term_taxonomy_id": "3",
"taxonomy": "category",
"description": "",
"parent": "0",
"count": "0"
},
"3": {
"term_id": "4",
"name": "abc",
"slug": "abc",
"term_group": "0",
"term_order": "4",
"term_taxonomy_id": "4",
"taxonomy": "category",
"description": "",
"parent": "0",
"count": "0"
},

"term_id": "1",

"term_order": "5",
"term_taxonomy_id": "1",
"taxonomy": "category",
"description": "",
"parent": "0",
"count": "1"
}
}
This is simply shows that it will be true only in case of id 1:
if($id == "1") {
I think this should be:
if(isset($id) && $id != '') {
to get the all the post.
i have a php script that execute a mysql query and return the result in json_encode format but there is a problem. It seems that json replaces space with carriage return.
This is my json encode response
