Below is my JSON file:
{
"example": "1",
"example2": 2,
"text": "3",
"info": {
"agent": 4,
"sum": 5,
"collection": [{
"Name": "6",
"Pic": "7"
} {
"Name": "8",
"Pic": "9"
}, {
"Name": "10",
"Pic": "11"
}]
}
}
How would I display each 'name' and 'pic' I think I need to use a foreach loop but don't know how to.
This is all the code I have:
$data = json_decode(file_get_contents('http://linktojson.com'));
echo $data['info']['collection'][0]['Name'];
echo $data['info']['collection'][0]['Pic'];
This should work
$data = json_decode(file_get_contents('http://linktojson.com'));
echo "<pre>".print_r($data,1)."</pre>";
foreach($data->info->collection as $key){
echo $key->Pic;
echo $key->Name;
}
Valid JSON

I'm retrieving data from a database and pushing it to arrays then use json_encode() to output in json format. I have ended up having the data in this format.
[
{
"category_id": "1",
"category_name": "Construction Materials"
},
{
"items": [
{
"id": "1",
"item_name": "Wire Mesh",
"price": "459",
"image_url": null
},
{
"id": "2",
"item_name": "Cement",
"price": "700",
"image_url": null
},
{
"id": "3",
"item_name": "Barbed Wire",
"price": "3000",
"image_url": null
},
{
"id": "4",
"item_name": "Iron sheet",
"price": "200",
"image_url": null
}
]
},
{
"category_id": "2",
"category_name": "Plumbing"
},
Here is what I want to achieve:
[
{
"category_id": "1",
"category_name": "Construction Materials"
"items": [
{
"id": "1",
"item_name": "Wire Mesh",
"price": "459",
"image_url": null
},
{
"id": "2",
"item_name": "Cement",
"price": "40",
"image_url": null
},
{
"id": "3",
"item_name": "Barbed Wire",
"price": "3000",
"image_url": null
},
{
"id": "4",
"item_name": "Iron sheet",
"price": "200",
"image_url": null
}
]
},
{
"category_id": "2",
"category_name": "Plumbing"
},
How can I achive this in php. Is it possible to edit the contents of the main array? how can I add "items" after "category_name"
Regards..
$array = json_decode($yourJson);
$arrayLength = count($array);
$finalArray = [];
for ($i=0; $i < $arrayLength; $i+=2) {
$finalArray[] = $array[$i] + $array[$i + 1];
}
$backToJson = json_encode($finalArray);
Alternative to Mattijs's answer.
function get_first_property($object) {
$properties = array_keys(get_object_vars($object));
return reset($properties);
}
function object_merge($object1, $object2) {
return (object) array_merge((array) $object1, (array) $object2);
}
// loop through each of the array objects
$previous_first_property = null;
foreach ($array as $i => $object) {
$first_property = get_first_property($object);
// merge if the 1st property is "items", and the previous 1st was "category_id"
if ($first_property == "items" && $previous_first_property == "category_id") {
$array[$i - 1] = object_merge($array[$i - 1], $array[$i]);
unset($array[$i]);
}
$previous_first_property = $first_property;

I've been struggling around this for a while now and can't seem to get the right algorithm.
What I want is to sort this:
$variable = '{
"0": {
"id": "0",
"code": "main_colour",
"label": "Main Colour",
"options": [{
"id": "825",
"label": "White",
"products": ["1", "2", "3"]
}, {
"id": "840",
"label": "Cream",
"products": ["3", "4", "5"]
}],
"position": "0"
},
"2": {
"id": "0",
"code": "size",
"label": "Size",
"options": [{
"id": "825",
"label": "S",
"products": ["1", "2", "3"]
}, {
"id": "840",
"label": "M",
"products": ["3", "4", "5"]
}],
"position": "0"
}
}';
And the output would be
$variable = '{
"0": {
"id": "0",
"code": "main_colour",
"label": "Main Colour",
"options": [{
"id": "840",
"label": "Cream",
"products": ["3", "4", "5"]
},{
"id": "825",
"label": "White",
"products": ["1", "2", "3"]
}],
"position": "0"
},
"2": {
"id": "0",
"code": "size",
"label": "Size",
"options": [{
"id": "840",
"label": "M",
"products": ["3", "4", "5"]
}, {
"id": "825",
"label": "S",
"products": ["1", "2", "3"]
}],
"position": "0"
}
}';
So basically it should be sorted using the label inside the "options" without affecting the other fields. I've been trying usort and tried different algorithms but to no avail.
Current code that sorts only the outside "label" and not the inner label:
function optionsSort($a, $b) {
return strcmp($a['options'][0]['label'], $b['options'][0]['options']['label']);
}
usort($variable, "optionsSort"));
Here's the code:
// your array
$variable = '{
"0": {
"id": "0",
"code": "main_colour",
"label": "Main Colour",
"options": [{
"id": "825",
"label": "White",
"products": ["1", "2", "3"]
}, {
"id": "840",
"label": "Cream",
"products": ["3", "4", "5"]
}],
"position": "0"
},
"2": {
"id": "0",
"code": "size",
"label": "Size",
"options": [{
"id": "825",
"label": "S",
"products": ["1", "2", "3"]
}, {
"id": "840",
"label": "M",
"products": ["3", "4", "5"]
}],
"position": "0"
}
}';
$a = json_decode($variable);
foreach ($a as $item) {
// sorting function
usort($item->options, function($a, $b) { return strcmp($a->label, $b->label); });
}
I am building an admin backend for an android app. My code provides a json output which the android developer then uses in his app. The developer asked me if it is possible to reduce the hierarchy level in the json output
as in remove the highlighted []0 and put the contents directly inside the []data instead.
This is my current php code
if($type == 1 ) //Handle item display
{
try
{
$query = "SELECT category FROM category";
$result= $DBH->query($query);
while($row = $result->fetch(PDO::FETCH_ASSOC))
{
$cat = $row['category'];
$query1 = "SELECT * FROM item WHERE catagory='$cat'";
$value = $DBH->query($query1);
if($row1 = $value->fetchAll(PDO::FETCH_OBJ)){
$main[] = array('data'=>array($row1));
}
else
{
$main[] = array('data'=>array('catagory'=>$row['category']));
}
}
echo json_encode($main);
$result->closeCursor(); //Close database connection free resources
$DBH = null;
}
catch(PDOException $e){
print $e->getMessage ();
die();
}
}
And the json output being generated
[
{
"data": [
[
{
"id": "2",
"name": "rice",
"price": "20",
"description": "Plain Rice",
"image": "4106_rice.jpg",
"time": "12 mins",
"catagory": "Lunch",
"subcat": ""
},
{
"id": "3",
"name": "item 1",
"price": "32",
"description": "item 1 description",
"image": "1370_2Ckjikljklkljh.jpg",
"time": "10",
"catagory": "Lunch",
"subcat": "Chicken Soup"
},
{
"id": "4",
"name": "hello",
"price": "10",
"description": "fgsdjfsfsdj",
"image": "",
"time": "76",
"catagory": "Lunch",
"subcat": ""
}
]
]
},
{
"data": {
"catagory": "Dinner"
}
},
{
"data": {
"catagory": "Soup"
}
},
{
"data": {
"catagory": "Test"
}
}
]
I am not very sure if I can make the changes he asked or if it is possible. Is it doable?
Your json structure is inconsistent and try this approach, will be easier for the developer to parse
{
"response": [
{
"data": [
{
"id": "2",
"name": "rice",
"price": "20",
"description": "Plain Rice",
"image": "4106_rice.jpg",
"time": "12 mins",
"catagory": "Lunch",
"subcat": ""
},
{
"id": "3",
"name": "item 1",
"price": "32",
"description": "item 1 description",
"image": "1370_2Ckjikljklkljh.jpg",
"time": "10",
"catagory": "Lunch",
"subcat": "Chicken Soup"
},
{
"id": "4",
"name": "hello",
"price": "10",
"description": "fgsdjfsfsdj",
"image": "",
"time": "76",
"catagory": "Lunch",
"subcat": ""
}
]
},
{
"data": [
{
"catagory": "Dinner"
}
]
},
{
"data": [
{
"catagory": "Soup"
}
]
},
{
"data": [
{
"catagory": "Test"
}
]
}
]
}
I have this JSON code:
{
"phrases": [
{
"phrases": [
{
"id": "33",
"text": "sasdsad",
"date": "2012-03-14 20:28:45",
"views": "0",
"ip": "64.191.90.5",
"reported": "0",
"strange": "0",
"lang": "en"
},
{
"id": "32",
"text": "que ondaa\r\n",
"date": "2012-03-14 20:27:45",
"views": "0",
"ip": "64.191.90.5",
"reported": "0",
"strange": "0",
"lang": "en"
},
{
"id": "31",
"text": "dsadssadsad",
"date": "2012-03-14 20:27:35",
"views": "0",
"ip": "64.191.90.5",
"reported": "0",
"strange": "0",
"lang": "en"
}
],
"details": {
"success": "true",
"phrase_id": "",
"phrase_text": "",
"phrase_date": ""
}
}
I don't really know what to do. I get some phrases vía MySQL, and pushes them to an array. This array is json_encoded() and gets printed.
$sth = $sql;
$rows = array();
while($r = mysql_fetch_assoc($sth)) {
$rows[] = $r;
}
$sth = $sql;
$data = array(
"success" => "true",
"phrase_id" => "",
"phrase_text" => "",
"phrase_date" => "",
);
print json_encode($rows).json_encode($data);
and with jQuery I was trying to parse it, but I can't. This is the main problem.
function getPhrases(order,limit,last){
var req_url = ...;
$.getJSON(req_url, function(data) {
$.each(data.phrases, function(i, data) {
appendPhrase(data.text);
lastid = data.id;
});
$.each(data.details, function(i, data) {
$("#phrases-count").html(data.totalcount);
});
});
}
PS: I was doing this with "echo" but got some problems.
{
"phrases": [
{
"id": "33",
"text": "sasdsad",
"date": "2012-03-14 20:28:45",
"views": "0",
"ip": "64.191.90.5",
"lang": "en"
},
{
"id": "32",
"text": "que ondaa<br />",
"date": "2012-03-14 20:27:45",
"views": "0",
"ip": "64.191.90.5",
"lang": "en"
},
{
"id": "31",
"text": "dsadssadsad",
"date": "2012-03-14 20:27:35",
"views": "0",
"ip": "64.191.90.5",
"lang": "en"
}
],
"details": [
{
"totalcount": "3",
"logged_in": "false"
}
]
}
You can't simply combine these JSON arrays:
print json_encode($rows).json_encode($data);
Try this (attempt 2):
print json_encode( array('phrases' => $rows, 'details' => $data) );
I have a document like this in mongodb
{
"_id": {
"$oid": "56b7451fa91b80e2078b4567"
},
"number": "222",
"value": "hello",
"name": "James",
"username": "mahsa",
"lessons": [
{
"id": "2",
"time": "2016-02-11 07:15:00",
"term": "3"
"marks": [
{
"id": "4",
"value": "10",
},
{
"id": "5",
"value": "9",
}
]
},
{
"id": "3",
"time": "2016-02-11 07:45:00",
"term": "4"
}
]
}
I'd like to push a nested array only when my variables are exactly this: array('number'=>'222','lessons.id'=>'2','lessons.term'=>'3')
after
"id": "2", "time": "2016-02-11 07:15:00", "term": "3"
, but when I use
array('number'=>'222','lessons.id'=>'2','lessons.term'=>'4')
or
array('number'=>'222','lessons.id'=>'3','lessons.term'=>'3')
has a similar result
my code is
$this->collection->update(
array('number'=>'222','lessons.id'=>'2','lessons.term'=>'3'),
array('$push'=>array(
'lessons.$.marks'=> array(
array('id'=>'444','value'=>'100'),
array('id'=>'555','value'=>'90')
))));
Can I solve this problem or mongo can't support somethings like this?
Mongo does support it, you just need to use the proper syntax:
{
'number': '222',
'lessons': {
'$elemMatch': {
'id' : '3',
'term': '3'
}
}
}, {
'$push': {
'lessons.$.marks': {
'$each': [{
'id': '444',
'value': '100'
}, {
'id': '555',
'value': '90'
}]
}
}
}
Here is probably what you need in PHP:
$this->collection->update(
array('number'=>'222',
array('$elemMatch'=>array('lessons.id'=>'2','lessons.term'=>'3')),
array('$push'=>array(
'lessons.$.marks'=> array(
'$each'=>array(
array('id'=>'444','value'=>'100'),
array('id'=>'555','value'=>'90')
)))));
