Im new to php and json. can you please suggest me on how to get the my desired output.
JSON File:
{
"1415772360":[
{"apple":"0"},
{"mango":"0"},
{"grapefruit":"0"},
{"melons":"12"},
{"peaches":"2"},
{"banana":"1"}
],
"1415772420":[
{"apple":"0"},
{"mango":"0"},
{"grapefruit":"0"},
{"melons":"7"},
{"peaches":"1"},
{"banana":"1"}
]
}
Desired Output
[
{
"minute":"1415772360",
"apple":"0",
"mango":"0",
"grapefruit":"0",
"melons":"12",
"peaches":"2",
"banana":"1”
},
{
"minute":"1415772420",
"apple:"0",
"mango":"0",
"grapefruit":"0",
"melons":"7",
"peaches":"1",
"banana":"1”
}
]
How can I do this in PHP?
I really appreciate your help. Thanks.
I would give json_decode a try. It won't get your desired output, but it will create an array from your JSON.
Documentation: http://php.net/manual/en/function.json-decode.php
My test:
$json = "{\"1415772360\":[{\"apple\":\"0\"},{\"mango\":\"0\"},{\"grapefruit\":\"0\"},
{\"melons\":\"12\"},{\"peaches\":\"2\"},{\"banana\":\"1\"}], \"1415772420\":
[{\"apple\":\"0\"},{\"mango\":\"0\"},{\"grapefruit\":\"0\"},{\"melons\":\"7\"},
{\"peaches\":\"1\"},{\"banana\":\"1\"}]}";
$new = json_decode($json);
print_r($new);
Output:
stdClass Object ( [1415772360] => Array ( [0] => stdClass Object ( [apple] => 0 )
[1] => stdClass Object ( [mango] => 0 ) [2] => stdClass Object ( [grapefruit] => 0 )
[3] => stdClass Object ( [melons] => 12 ) [4] => stdClass Object ( [peaches] => 2 )
[5] => stdClass Object ( [banana] => 1 ) ) [1415772420] => Array ( [0] => stdClass Object ( [apple] => 0 )
[1] => stdClass Object ( [mango] => 0 ) [2] => stdClass Object ( [grapefruit] => 0 )
[3] => stdClass Object ( [melons] => 7 ) [4] => stdClass Object ( [peaches] => 1 )
[5] => stdClass Object ( [banana] => 1 ) ) )
tyteen4a03 is correct that this just requires some looping to re-write the structure. This would be done as follows:
// Original JSON string
$json = '{
"1415772360":[
{"apple":"0"},
{"mango":"0"},
{"grapefruit":"0"},
{"melons":"12"},
{"peaches":"2"},
{"banana":"1"}
],
"1415772420":[
{"apple":"0"},
{"mango":"0"},
{"grapefruit":"0"},
{"melons":"7"},
{"peaches":"1"},
{"banana":"1"}
]
}';
// Convert JSON to array
$content = json_decode($json);
// Create new array container
$crate = array();
// Get minutes
foreach ($content AS $minute => $fruitbasket) {
$tmp = new stdClass;
$tmp->minutes = $minute;
// Get array of objects
foreach ($fruitbasket AS $fruits)
{
// Get object element and value
foreach ($fruits AS $key => $value)
{
// add to temporary object
$tmp->$key = $value;
}
}
// write to new array
$crate[] = $tmp;
}
print(json_encode($crate));

I'm trying to sort the following data by the date in the key and the value of Name.
The aim is to a get nice date ordered array with all the Names from the inner array in alphabetical order.
Array
(
[2017-07-27] => Array
(
[0] => stdClass Object
(
[Job] => stdClass Object
(
[Name] => Orange
)
)
[4] => stdClass Object
(
[Job] => stdClass Object
(
[Name] => Apple
)
)
)
[2017-07-22] => Array
(
[6] => stdClass Object
(
[Job] => stdClass Object
(
[Name] => Apple
)
)
[7] => stdClass Object
(
[Job] => stdClass Object
(
[Name] => Orange
)
)
)
[2017-07-29] => Array
(
[9] => stdClass Object
(
[Job] => stdClass Object
(
[Name] => Orange
)
)
[11] => stdClass Object
(
[Job] => stdClass Object
(
[Name] => Plumb
)
)
)
)
I'm pretty sure I should be using array_multisort but can't quite get the desired results.
You must split the code if you want to order on object properties, use the usort function.
Where $arr is your array:
uksort($arr, 'dateCmp');
foreach($arr as &$sub){
usort($sub, 'propCmp');
}
function dateCmp($a, $b){
return (strtotime($a) < strtotime($b) ? -1 : 1);
}
function propCmp($a, $b){
return ($a->Job->Name < $b->Job->Name ? -1 : 1);
}
Please try below code,
$sorted_vals = array();
ksort($multiArrs);
foreach($multiArrs as $key => $value) { // $multiArrs = your data array
$columns = null;
foreach ($value as $index => $element) {
$columns[] = $element->Job;
}
$temp = $value;
array_multisort($columns, SORT_ASC, $temp);
$sorted_vals[$key] = $temp;
}
I get the following output using print_r in php of my decoded JSON:
stdClass Object
(
[assignments] => Array
(
[0] => stdClass Object
(
[assignmentid] => 1
[grades] => Array
(
[0] => stdClass Object
(
[id] => 1
[userid] => 3
[attemptnumber] => 0
[timecreated] => 1484244192
[timemodified] => 1484244203
[grader] => 2
[grade] => 85.00000
)
)
)
)
[warnings] => Array
(
)
)
I want to get the value for [grade] => 85.00000 and store it in a variable. How would I go about doing this?
What about:
$var = $obj->assignments[0]->grades[0]->grade;
Use true as second parameter of json_decode() to decode it to array and then you have to loop over your result.
$data = json_decode($json, true);
foreach ($data['assignments'] as $row) {
foreach ($row['grades'] as $grade) {
echo $grade['grade'];
}
}
I want to merge the 2 arrays of objects based on the 'id' field of Array1 and the 'itemVendorCode' of Array2. I also wanted to remove from the resulting arrays of object anything that didn't match.
Array1:
Array
(
[0] => stdClass Object
(
[id] => 10-423-1176
[qty] => 2
[price] => 12.6
)
[1] => stdClass Object
(
[id] => 89-575-2354
[qty] => 24
[price] => 230.35
)
[2] => stdClass Object
(
[id] => 89-605-1250
[qty] => 2
[price] => 230.35
)
)
Array2:
Array
(
[0] => Item Object
(
[internalId] => 14062
[itemVendorCode] => 89-605-1250
)
[1] => Item Object
(
[internalId] => 33806
[itemVendorCode] => 89-575-2354
)
[2] => Item Object
(
[internalId] => 64126
[itemVendorCode] => 26-295-1006
)
)
I was able to solve this by this code:
$indexed = array();
foreach($itemsArray as $value) {
$indexed[$value->itemVendorCode] = $value;
}
$results = array();
foreach($vendorItems as $obj) {
$value = $indexed[$obj->id];
if (isset($value)) {
foreach($value as $name => $val) {
$obj->$name = $val;
array_push($results, $obj);
}
}
}
print_r($results);
credits to the original poster. I just modified it a bit,
I was able to get the result like this:
Array
(
[0] => stdClass Object
(
[id] => 10-423-1176
[qty] => 2
[price] => 12.6
[internalId] => 2035
[itemVendorCode] => 10-423-1176
)
[1] => stdClass Object
(
[id] => 10-423-1176
[qty] => 2
[price] => 12.6
[internalId] => 2035
[itemVendorCode] => 10-423-1176
)
[2] => stdClass Object
(
[id] => 14-102-1010
[qty] => 16
[price] => 3.2
[internalId] => 57033
[itemVendorCode] => 14-102-1010
)
)
I think you will have to use array_map function which provides you a callback function to execute on array(s).
In the callback function:
- declare your array1
- foreach the second array
- set an if statement to check that the current iteration with the id value matches the itemVendorCode of the array2 and return it
something like this:
// You have to specify to PHP to use a local copy of your $array2 to works with it into your callback
$cb = function ($obj1) use ($array2)
{
// you foreach this array
foreach ($array2 as $obj2) {
// if the value of id matches itemVendorCode
if ($obj1->id === $obj2->itemVendorCode) {
// you return the id
return $obj->id;
}
}
};
// this function will fill a new array with all returned data
$mergedArray = array_map($cb, $array1);
This code is a sample but doesn't provide you, your needled solution, try to update it to do what you exactly want ;)

I need to get the id and name in an HTML table, but I seem to have a hard time iterating through this object. TIA. I understand that I need to get to the Values Array, and then to the group object, but I trip over the transitions between object and array and foreach vs index based iteration.
For example I tried this:
foreach ($res as $values) { print "\n"; print_r ($values); }
It iterates trough the object, but it also gives me useless
10 0 37
echo "<table>"
foreach ($object->values as $arr) {
foreach ($arr as $obj) {
$id = $obj->group->id;
$name = $obj->group->name;
$html = "<tr>";
$html .= "<td>Name : $name</td>";
$html .= "<td>Id : $id</td>";
$html .= "</tr>";
}
}
echo "</table>";
Since this is the top result in Google if you search for iterate over stdclass it may be helpful to answer the question in the title:
You can iterate overa stdclass simply by using foreach:
$user = new \stdClass();
$user->flag = 'red';
foreach ($user as $key => $value) {
// $key is `flag`
// $value is `red`
}
function objectToArray( $data )
{
if ( is_object( $data ) )
$d = get_object_vars( $data );
}
Convert the Object to array first like:
$results = objectToArray( $results );
and use
foreach( $results as result ){... ...}
I know it's an old post , but for sake of others:
when working with stdClass you should use Reflections:
$obj = new ReflectionObject($object);
$propeties = $obj->getProperties();
foreach($properties as $property) {
$name = $property->getName(); <-- this is the reflection class
$value = $object->$name; <--- $object is your original $object
here you need to handle the result (store in array etc)
}
foreach($res->values as $value) {
print_r($value);
}
I have an array like this (output from print_r):
Array
(
[price] => 700.00
[room_prices] => Array
(
[0] =>
[1] =>
[2] =>
[3] =>
[4] =>
)
[bills] => Array
(
[0] => Gas
)
)
I'm running a custom function to convert it to an object. Only the top-level should be converted, the sub-arrays should stay as arrays. The output comes out like this:
stdClass Object
(
[price] => 700.00
[room_prices] => Array
(
[0] => Array
)
[bills] => Array
(
[0] => Array
)
)
Here is my conversion function. All it does is set the value of each array member to an object:
function array_to_object( $arr )
{
$obj = new stdClass;
if ( count($arr) == 0 )
return $obj;
foreach ( $arr as $k=>$v )
$obj->$k = $v;
return $obj;
}
I can't figure this out for the life of me!
why don't you just cast the array to an object?
$myObj = (object) $myArray;
I can't reproduce (PHP 5.3):
$a = array(
"price" => 700.00,
"room_price" => array(NULL, NULL, NULL, NULL, NULL),
bills => array("Gas"),
);
function array_to_object( $arr )
{
$obj = new stdClass;
if ( count($arr) == 0 )
return $obj;
foreach ( $arr as $k=>$v )
$obj->$k = $v;
return $obj;
}
print_r(array_to_object($a));
gives
stdClass Object
(
[price] => 700
[room_price] => Array
(
[0] =>
[1] =>
[2] =>
[3] =>
[4] =>
)
[bills] => Array
(
[0] => Gas
)
)
