How can I replace the locations here with a foreach loop? When I put the foreach inside of the array, the code breaks. I guessing the answer has to do with creating a foreach variable and then entering that for the levels value instead?
This is my array
$data = array(
'name' => Locations,
'data' => '{
"title":"USA",
"location":"World",
"levels":[
{
"id":"states",
"title":"States",
"locations":[
{
"id":"ca",
"title":"California",
"pin":"hidden",
"x":"0.0718",
"y":"0.4546",
},
{
"id":"wa",
"title":"Washington",
"pin":"hidden",
"x":"0.1331",
"y":"0.0971"
}
]
}
]
}'
Here is my current foreach.
foreach ($response->records as $record) {
$id = $record->Id;
$title = $record->Title;
$pin = $record->Pin;
$x = $record->X;
$y = $record->Y;
echo {
"id": $id,
"title": $title,
"pin": $pin,
"x": $x,
"y": $y
}
}
Any help would be appreciated.
$arr = array();
foreach ($response->records as $record) {
$r['id'] = $record->Id;
$r['title'] = $record->Title;
$r['pin'] = $record->Pin;
$r['x'] = $record->X;
$r['y'] = $record->Y;
$arr[] = $r;
}
echo json_encode($arr);

I need to create a JSON object, in PHP, with the following form
{
"Routes": [{
"route_ID": "49",
"geom": [{
"lat": "-30.63607",
"lng": "147.499935"
}, {
"lat": "-30.63631",
"lng": "147.499868"
}]
},
{
"route_ID": "50",
"geom": [{
"lat": "-30.63607",
"lng": "147.499935"
}, {
"lat": "-30.63631",
"lng": "147.499868"
}]
}
]
}
The problem with my code is that I can't seem to find a way of concatenating the JSON elements from the $jsonString, The code as it is just produces "route_ID": "50".
(Yes I agree there are a great many questions on stackoverflow on this question, but they just about all refer to single elements derived from a static array). By the way, I am given the $jsonString and need to preprocess it in the code below.
$jsonString = "[{\"route_ID\":\"49\",\"geom\":\"<LineString><coordinates>147.499935,-30.63607 <\\/coordinates><\\/LineString>\"},{\"route_ID\":\"50\",\"geom\":\"<LineString><coordinates>147.499935,-30.63607<\\/coordinates><\\/LineString>\"}]";
/* PHP Code */
$jsonArray = json_decode($jsonString, true);
$json = new stdClass();
$json_Routes = new stdClass();
$route_geom_Array = array();
foreach ($jsonArray as $record) {
print_r($record);
$geomString = $record["geom"];
$geomString = str_replace('<LineString><coordinates>', ' ', $geomString);
$geomString = str_replace('</coordinates></LineString>', ' ', $geomString);
$geomString = trim($geomString);
$route_geom_Array = explode(' ', $geomString);
for ($i = 0; $i < sizeof($route_geom_Array); $i++) {
$var = explode(',', $route_geom_Array[$i]);
$route_geom[] = array('lat' => $var[1], 'lng' => $var[0]); // lat long
}
$json->route_ID = $record["route_ID"]; //<- Problem area
$json->geom = $route_geom; //<- Problem area
}
$json_Routes->Routes = $json;
$jsonArray = json_encode($json_Routes);
echo $jsonArray;
exit ();`
Can someone give me a clue on how do this.
Thanks
You need to make $json_Routes->Routes an array and push the $json structures within the foreach block, e.g.:
$json_Routes->Routes = [];
foreach ($jsonArray as $record) {
// Existing code ...
$json_Routes->Routes[] = $json;
}
You need to push objects to array, here solution :
$jsonArray = json_decode($jsonString, true);
$json_Routes = new stdClass();
$route_Array = [];
$route_geom_Array = [];
$route_ID_Array = [];
$items = [];
$index = 0;
foreach ($jsonArray as $record) {
//print_r($record);
$geomString = $record["geom"];
$geomString = str_replace('<LineString><coordinates>', ' ', $geomString);
$geomString = str_replace('</coordinates></LineString>', ' ', $geomString);
$geomString = trim($geomString);
$route_geom_Array = explode(' ', $geomString);
for ($i = 0; $i < sizeof($route_geom_Array); $i++) {
$var = explode(',', $route_geom_Array[$i]);
$route_geom[] = array('lat' => $var[1], 'lng' => $var[0]); // lat long
}
$json = new stdClass();
$json->route_ID = $record["route_ID"]; //<- Problem area
$json->geom = $route_geom; //<- Problem area
array_push($route_Array,$json);
}
$json_Routes->Routes = $route_Array;
$result = json_encode($json_Routes);
echo $result;
exit();
I'm trying to decode a json string, i want to get just langlinks value,
my json string is:
{
"batchcomplete": "",
"query": {
"pages": {
"105219": {
"pageid": 105219,
"ns": 0,
"title": "Cancer",
"langlinks": [
{
"lang": "ar",
"*": "\u0633\u0631\u0637\u0627\u0646"
}
]
}
}
}
}
I tried this code:
$results = json_decode($api_response, true);
$list = array();
foreach ($results['query']['pages'] as $k => $v)
{
var_dump($v);
foreach($v as $key => $val)
{
array_push($list, $val);
}
}
return $list;
But it does not accede to the value that I want, when i add
var_dump(array_key_exists('langlinks', $v));
it gives me false :/
I just tested this and this seems to return true
$source = file_get_contents('https://en.wikipedia.org/w/api.php?action=query&titles=Cancer&prop=langlinks&lllang=ar&format=json');
$results = json_decode($source, true);
foreach ($results['query']['pages'] as $k => $v)
{
var_dump(array_key_exists('langlinks', $v));die();
}
If you are still having trouble, maybe you can post more code?
$list = array();
$src = json_decode($api_response, true);
foreach ($src['query']['pages'] as $key => $langData) {
foreach ($langData['langlinks'] as $k => $ld);
// var_dump($ld['*']);
}
return $ld['*'];
I want to send nested JSON array.Which contain following format.
${"posts":[{
"abc":"123",
"xyz":"123",
"pro":[{
"name":"Brinjal",
"qty":"500 gms"
},
{
"name":"Brinjal",
"qty":"500 gms"
}]
}]
}
Here is my php code:
$rows = $stmt->fetchAll();
if ($rows) {
$order["posts"] = array();
foreach ($rows as $row) {
$post = array();
$post["order_id"] = $row["order_id"];
$post["order_totalamount"] = $row["order_totalamount"];
$post["address"] = $row["address"];
$post["pincode"] = $row["pincode"];
$post["delivery_timeslot"] = $row["delivery_timeslot"];
$post["order_date"] = $row["order_date"];
$query1= "query";
$rows1 = $stmt->fetchAll();
if ($rows1) {
foreach ($rows1 as $row1) {
$query2= "query";
$rows2 = $stmt->fetchAll();
$post["product"] = array();
if ($rows2) {
$products = array();
foreach ($rows2 as $row2) {
$products["product_name"]=$row2["product_name"];
$products["prod_qty"] = $row2["product_minquantity"];
}
array_push($post["product"],$products);
echo json_encode($products);
}
}
}
array_push($order["posts"], $post);
}
echo json_encode($order);
}
From above code I got result:
$ {"posts":
[{
"order_id":"18",
"order_totalamount":"40",
"address":"2, Chetan Society, Vadodara",
"pincode":"390023",
"delivery_timeslot":"Zone wise delivery",
"order_date":"2016-03-18 17:50:53",
"product":[{"product_name":"Brinjal","prod_qty":"500 gms"}]
}]
}
But my actual product array is:
${"product_name":"Banana","prod_qty":"1 Kg"}{"product_name":"Brinjal","prod_qty":"500 gms"}
Kindly help out. I am stuck on it. tried a lot but did not get success.
In
foreach ($rows2 as $row2) {
$products["product_name"]=$row2["product_name"];
$products["prod_qty"] = $row2["product_minquantity"];
}
You overwrite $products["product_name"]and $products["prod_qty"] with the values of the last $row2.
The line {"product_name":"Banana","prod_qty":"1 Kg"}{"product_name":"Brinjal","prod_qty":"500 gms"} actually consists of two echo's:
{"product_name":"Banana","prod_qty":"1 Kg"}
{"product_name":"Brinjal","prod_qty":"500 gms"}
But you don't see the difference. I suggest echoing a string in-between them or use something like var_dump() to see how many values you're echoing.
You should do something like:
for ($i = 0; $i < count($rows2); $i++) {
$products[$i]["product_name"]=$rows2[$i]["product_name"];
$products[$i]["prod_qty"] = $rows2[$i]["product_minquantity"];
}
This will result in: [{"product_name":"Banana","prod_qty":"1 Kg"},{"product_name":"Brinjal","prod_qty":"500 gms"}]
FYI $array[] = has the same rsults as array_push(), but had less overhead of calling array_push().
EDIT:
Below a complete example since it doesn't seem to workout for you:
//Demo $order
$order = array (
'posts' =>
array (
0 =>
array (
'order_id' => '18',
'order_totalamount' => '40',
'address' => '2, Chetan Society, Vadodara',
'pincode' => '390023',
'delivery_timeslot' => 'Zone wise delivery',
'order_date' => '2016-03-18 17:50:53',
),
),
);
//Demo $rows2
$rows2 = array(
array(
'product_name' => 'banana',
'product_minquantity' => '1 Kg'
),
array(
'product_name' => 'Brinjal',
'product_minquantity' => '500 gms'
)
);
$post['product'] = array();
if ($rows2) {
$products = array();
for ($i = 0; $i < count($rows2); $i++) {
$products[$i]['product_name'] = $rows2[$i]['product_name'];
$products[$i]['prod_qty'] = $rows2[$i]['product_minquantity'];
}
$post['product'] = $products;
echo json_encode($products); //[{"product_name":"banana","prod_qty":"1 Kg"},{"product_name":"Brinjal","prod_qty":"500 gms"}]
}
//$order['posts'][] = $post;
$order['posts'][0] = $order['posts'][0] + $post;
//In this example I only have 1 item in $order['posts'] so I know to add to key 0.
//In your case you need to know which key of $rows1 you need to do the adding.
//Change the foreach loop of $rows to a for loop as well so you can define your own keynames ($i).
echo '<br>==================================================================<br>';
echo json_encode($order);

I need help with my json output. At present my output is as so:
[
[
{
"ING_SW_CB": "5",
"SB_SW_CB": "3",
"NG3_SW_CB": "1",
"Mould_Close": "4",
"Leak_Test": "5",
"ML_Load": "6",
"Pre_Heat": "3",
"Dispense": "9",
"A310": "7",
............
}
]
]
I’d like it to be as following with "key" & "value" included in the output.
{"key":"ING_SW_CB", "value": "5"},
{"key":"SB_SW_CB", "value": "3"},
..............................
Hers is my PHP script:
$json_response = array();
while ($row = mysqli_fetch_array($result2, MYSQL_ASSOC)) {
$row_array['ING_SW_CB'] = $row['ING_SW_CB'];
$row_array['SB_SW_CB'] = $row['SB_SW_CB'];
$row_array['NG3_SW_CB'] = $row['NG3_SW_CB'];
$row_array['Mould_Close'] = $row['Mould_Close'];
$row_array['Leak_Test'] = $row['Leak_Test'];
$row_array['ML_Load'] = $row['ML_Load'];
$row_array['Pre_Heat'] = $row['Pre_Heat'];
$row_array['Dispense'] = $row['Dispense'];
$row_array['A310'] = $row['A310'];
$row_array['Gelation'] = $row['Gelation'];
$row_array['Platen'] = $row['Platen'];
$row_array['Mainline_Unload'] = $row['Mainline_Unload'];
$row_array['De_mould'] = $row['De_mould'];
$row_array['Clean_Up'] = $row['Clean_Up'];
$row_array['Soda_Blast'] = $row['Soda_Blast'];
$row_array['Miscellaneous'] = $row['Miscellaneous'];
//push the values in the array
array_push($json_response,$row_array);
}
$json_data = json_encode($json_response, JSON_PRETTY_PRINT);
file_put_contents('your_json_file.json', $json_data);
I need the keywords "key" & "value" added to the output so I can popuate a D3 chart.
You need to loop on the row's results and build more arrays:
while(...) {
$temp = array();
foreach($row as $key => $value) {
$temp[] = array('key' => $key, 'value' => $value);
}
$json_response[] = $temp;
}
Loop over the columns:
$json_response = array();
while ($row = mysqli_fetch_array($result2, MYSQLI_ASSOC)) {
$json_row = array();
foreach ($row as $key => $value) {
$json_row[] = array('key' => $key, 'value' => $value);
}
$json_response[] = $json_row;
}
$json_data = json_encode($json_response, JSON_PRETTY_PRINT);
file_put_contents('your_json_file.json', $json_data);
$json_response = array();
while ($row = mysqli_fetch_array($result2, MYSQL_ASSOC)) {
//push the values in the array
foreach($row as $k=>$v){
$my_array = array("key"=>$k, "value"=>$v);
}
array_push($json_response,$my_array);
}
$json_data = json_encode($json_response, JSON_PRETTY_PRINT);
file_put_contents('your_json_file.json', $json_data);
I am having a string below
$string = ot>4>om>6>we>34>ff>45
I would like the JSON output be like
[{"name":"website","data":["ot","om","we","ff"]}]
and
[{"name":"websitedata","data":["4","6","34","45"]}]
what I've tried
$query = mysql_query("SELECT month, wordpress, codeigniter, highcharts FROM project_requests");
$category = array();
$category['name'] = 'website';
$series1 = array();
$series1['name'] = 'websitedata';
while($r = mysql_fetch_array($query)) {
$category['data'][] = $r['month'];
}
$result = array();
array_push($result,$category);
array_push($result,$series1);
print json_encode($result, JSON_NUMERIC_CHECK);
but the above code is applicable only if the data are present in rows from a mysql table, what i want is achieve the same result with the data from the above string. that is
$string = ot>4>om>6>we>34>ff>45
NEW UPDATE:
I would like to modify the same string
$string = ot>4>om>6>we>34>ff>45
into
json output:
[
{
"type" : "pie",
"name" : "website",
"data" : [
[
"ot",
4
],
[
"om",
6
],
[
"we",
34
]
]
}
]
I have updated the answer please check the json part, I would like the php code.
regards
You can explode() on the >s, and then loop through the elements:
$string = "ot>4>om>6>we>34>ff>45";
$array1 = [
'name'=>'website',
'data'=>[]
]
$array2 = [
'name'=>'websitedata',
'data'=>[]
]
foreach(explode('>', $string) as $index => $value){
if($index & 1) //index is odd
$array2['data'][] = $value;
else //index is even
$array1['data'][] = $value;
}
echo json_encode($array1); //prints {"name":"website","data":["ot","om","we","ff"]}
echo json_encode($array2); //prints {"name":"websitedata","data":["4","6","34","45"]}
A solution using preg_match_all():
$string = "ot>4>om>6>we>34>ff>45";
preg_match_all('/(\w+)>(\d+)/', $string, $matches);
$array1 = [
'name'=>'website',
'data'=> $matches[1]
];
$array2 = [
'name'=>'websitedata',
'data'=> $matches[2]
];
echo json_encode($array1); //prints {"name":"website","data":["ot","om","we","ff"]}
echo json_encode($array2); //prints {"name":"websitedata","data":["4","6","34","45"]}
Update:
To get the second type of array you wanted, use this:
//since json_encode() wraps property names in double quotes (which prevents the chart script from working), you'll have to build the json object manually
$string = "ot>4>om>6>we>34>ff>45";
preg_match_all('/(\w+)>(\d+)/', $string, $matches);
$data = [];
foreach($matches[1] as $index => $value){
if(isset($matches[2][$index]))
$data[] = '["' . $value . '",' . $matches[2][$index] . ']';
}
$type = 'pie';
$name = 'website';
echo $jsonString = '[{type:"' . $type . '",name:"' . $name . '",data:[' . implode(',', $data) . ']}]'; // prints [{type:"pie",name:"website",data:[["ot",4],["om",6],["we",34],["ff",45]]}]
Update #2:
This code uses explode(), and although it's probably not the most efficient way of doing it, it works.
//since json_encode() wraps property names in double quotes (which prevents the chart script from working), you'll have to build the json object manually
$string = "ot>4>om>6>we>34>ff>45";
$keys = [];
$values = [];
foreach(explode('>', $string) as $key => $value){
if(!($key & 1)) //returns true if the key is even, false if odd
$keys[] = $value;
else
$values[] = $value;
}
$data = [];
foreach($keys as $index => $value){
if(isset($values[$index]))
$data[] = '["' . $value . '",' . $values[$index] . ']';
}
$type = 'pie';
$name = 'website';
echo $jsonString = '[{type:"' . $type . '",name:"' . $name . '",data:[' . implode(',', $data) . ']}]'; // prints [{type:"pie",name:"website",data:[["ot",4],["om",6],["we",34],["ff",45]]}]
This should work, though there are probably better ways to do it.
$string = "ot>4>om>6>we>34>ff>45";
$website = ["name" => "website", "data" => []];
$websiteData = ["name" => "websitedata", "data" => []];
foreach(explode(">", $string) as $i => $s) {
if($i % 2 === 0) {
$website["data"][] = $s;
} else {
$websiteData["data"][] = $s;
}
}
echo json_encode($website);
echo json_encode($websiteData);
A regex alternative:
preg_match_all("/([a-z]+)>(\d+)/", $string, $matches);
$website = ["name" => "website", "data" => $matches[1]];
$websiteData = ["name" => "websitedata", "data" => $matches[2]];
Try this code:
$string = 'ot>4>om>6>we>34>ff>45';
$string_split = explode('>', $string);
$data = array("name" => "website");
$data2 = $data;
foreach ($string_split as $key => $value)
{
if (((int)$key % 2) === 0)
{
$data["data"][] = $value;
}
else
{
$data2["data"][] = $value;
}
}
$json1 = json_encode($data, JSON_NUMERIC_CHECK);
$json2 = json_encode($data2, JSON_NUMERIC_CHECK);
echo $json1;
echo $json2;
Output:
{"name":"website","data":["ot","om","we","ff"]}
{"name":"website","data":[4,6,34,45]}
Regards.
Try this snippet:
$strings = explode('>', 'ot>4>om>6>we>34>ff>45');
// print_r($string);
$x = 0;
$string['name'] = 'website';
$numbers['name'] = 'websitedata';
foreach ($strings as $s)
{
if ($x == 0) {
$string['data'][] = $s;
$x = 1;
} else {
$numbers['data'][] = $s;
$x = 0;
}
}
print_r(json_encode($string));
echo "<br/>";
print_r(json_encode($numbers));
As usual - it is long winded but shows all the steps to get to the required output.
