What I'm trying to do:
Get results from the database.
Get required values by assigning to an stdClass.
Put those objects in array. (<-The problem)
And output as JSON.
The objects are fine they get correct values. But when they are assigned to the array once, they replace all previous array values.
I'm using CodeIgniter to do the DB stuff.
The function:
function get_prizes(){
//All prize objects are stored here
$prizes = array();
//Prize object
$prize = new stdClass();
$prize->name1 = '';
//$prize->type = '';
//Getting the prizes from a simple database table
$query = $this->db->get('prizes');
if($query->num_rows() > 0){
foreach ($query->result() as $row):
$prize_name = $row->prize_name;
$prize->name1 = $prize_name;
//$prize->type = $prize_name;
$prizes[] = $prize;
echo " Item: " . print_r($prizes, true) . "<br>";
endforeach;
}
echo json_encode($prizes);
}
Output:
Item: Array ( [0] => stdClass Object ( [name1] => Radio ) )
Item: Array ( [0] => stdClass Object ( [name1] => Television ) [1] => stdClass Object ( [name1] => Television ) )
Item: Array ( [0] => stdClass Object ( [name1] => Toaster ) [1] => stdClass Object ( [name1] => Toaster ) [2] => stdClass Object ( [name1] => Toaster ) )
[{"name1":"Toaster"},{"name1":"Toaster"},{"name1":"Toaster"}]
I've tried array_push(). Also does the same thing.
You need to instantiate the object inside foreach loop:
function get_prizes()
{
// All prize objects are stored here
$prizes = array();
// Getting the prizes from a simple database table
$query = $this->db->get('prizes');
if ($query->num_rows() > 0) {
foreach($query->result() as $row):
// Prize object
$prize = new stdClass();
// $prize->type = '';
$prize->name1 = $row->prize_name;
$prizes[] = $prize;
endforeach;
}
echo json_encode($prizes);
}

I have below type of array, now I want to get count of it's subarray
For example I want to get count key 7 & 8. How to do it ? Any solution for that ? I tried but but no success :(
Array
(
[0] => stdClass Object
(
[id] => 4
[Blogdata] => stdClass Object
(
[7] => Array
(
[0] => stdClass Object
(
[blog_id] => 105
)
)
[8] => Array
(
[0] => stdClass Object
(
[blog_id] => 101
)
)
)
)
)
$date_count = array();
foreach($FeaturedBlogs as $Key=>$date) {
foreach($date as $d) {
$key = array_keys($d); // get our date
// echo $key;echo "<br>";
print_r($d);
$date_count[$key[0]]++;
}
}
Try this....
//Count Sub Array
$final_array = [];
$x = 0;
function countSubArray($data)
{
global $final_array;
global $x;
foreach($data as $key)
{
if(is_array($key))
{
$final_array[$x][0] = "1";
$final_array[$x][1] = json_encode($key);
$final_array[$x][2] = count((array)$key);
$x++;
countSubArray($key);
}
if(is_object($key))
{
$final_array[$x][0] = "2";
$final_array[$x][1] = json_encode($key);
$final_array[$x][2] = count((array)$key);
$x++;
countSubArray($key);
}
}
}
// Call Function...
countSubArray($arr); // what array you count..
// Display Sub Array Count...
$t_count = 0;
foreach($final_array as $d)
{
if($d[0] == 1)
{
echo "Array Count :".$d[2]." Array : ".$d[1]."<br>";
$t_count++;
}
}
echo "Total Array Count :".$t_count;
output of this example is...
Array
(
[0] => stdClass Object
(
[id] => 4
[Blogdata] => stdClass Object
(
[7] => Array
(
[0] => stdClass Object
(
[blog_id] => 135
)
)
[8] => Array
(
[0] => stdClass Object
(
[blog_id] => 101
)
)
)
)
)
Array Count :1 Array : [{"blog_id":135}]
Array Count :1 Array : [{"blog_id":101}]
Total Array Count :2

This is going to use a function as it's own callback function. The function will loop through an object or an array and test each element to see if it is another object or array.
If it did find a new object or array, then the function calls itself again to perform the same operations on the element, effectively traversing through your entire array.
When it has found the bottom of each element it will return the value of the counter which was keeping track of how many arrays it came across.
Like so:
function arrayCounter($data){
//At this point we have an array or an object.
//Lets loop across the elements and see if we have any more nested arrays or objects.
foreach($data as $key){
$count = 0;
//Test each element to see if it's an object or an array.
if(is_array($key) || is_object($key)){
//If it is we are going to send the element through another instance of the function.
$count += arrayCounter($key);
}
//If the element is an array we are going to increment the counter.
if(is_array($key)){
$count++;
}
}
return $count;
}
$count = arrayCounter($data);
echo 'Count: ' . $count; //Using your data this will return "2".
Hope it helps!
I have an existing JSON array:
stdClass Object
(
[set] => Array
(
[0] => stdClass Object
(
[name] => agenda
)
[1] => stdClass Object
(
[name] => first aid
)
)
)
I need to add a new key to it, so the final JSON result is something like this:
set: [{
name: 'agenda',
value: 'Agenda'
}, {
code: 'first aid',
value: 'First Aid'
}],
This is what I've done so far:
$result = array();
foreach ($data->set as $k => $row) {
$result['name'][$k] = $row->name;
$result['value'][$k] = ucwords($row->name);
}
But I have ended up with:
Array
(
[name] => Array
(
[0] => agenda
[1] => aid kit
)
[value] => Array
(
[0] => Agenda
[0] => First Aid
)
)
How can I merge the above so the name and value keys are in pair rather then being separate?
Update $row directly to modify your existing $data:
foreach ($data->set as $row) {
$row->value = ucwords($row->name);
}
To do it the way you are attempting:
$result = $data;
foreach ($data->set as $k => $row) {
$result->set[$k]->value = ucwords($row->name);
}
Notice, $row is an object.
Your try this
$result = array();
$count = 0;
foreach ($data->set as $k => $row) {
$result[$count]['name'] = $row->name;
$result[$count]['value'] = ucwords($row->name);
$count++;
}
result this
Array
(
[0] => stdClass Object
(
[name] => agenda
[value] => Agenda
)
[1] => stdClass Object
(
[name] => first aid
[value] => First Aid
)
)
If you want to modify your existing object, you can just set the value property directly.
foreach ($data->set as $row) {
$row->value = ucwords($row->name);
}
If you want to create a result without modifying your original object or leaving references to its internal objects, you can clone each of the internal objects and add the new properties to the cloned objects.
$result = array();
foreach ($data->set as $k => $row) {
$obj = clone $row;
$obj->value = ucwords($row->name);
$result[$k] = $obj;
}
I am pretty new with associative arrays. Just trying to create a dynamic associative array.
Current Array -
stdClass Object
(
[354] => Array
(
)
[355] => Array
(
)
)
Trying to get desired output
stdClass Object
(
[354] => Array
(
[activity_desc] = "description"
)
[355] => Array
(
[activity_desc] = "description"
)
)
wrote an sql to check key (354, 355) and return description.
How to I store key and value under 344 & 355?
Current code:
foreach ($report as $key=>$value)
{
$where = 'item_id = ' . $key . '';
$query = $db->prepare('SELECT activity_desc FROM program WHERE '. $where);
$query->execute();
$test = $query->fetch(PDO::FETCH_OBJ);
}
this is my sql return query for 354. 355 will be roughly the same.
stdClass Object ( [activity_desc] => <p>Send Activity</p>
Thanks in advance

wow it was that simple........
$report->$key = $test;
I try to create an generic object which needs to be structuered like this:
[Content] => stdClass Object
(
[item] => Array
(
[0] => stdClass Object
(
[Value] => STRING
)
)
[item] => Array
(
[0] => stdClass Object
(
[Value] => ANOTHER STRING
)
)
)
This is my code:
$content = new stdClass();
$data = file('filname.csv');
foreach($data as $key => $val) {
$content->item->Value = $val;
}
This overwrites itself each time the loop iterates. By defining item as an array like this:
$content->item = array();
...
$content->item[]->Value = $val;
...the result is also not the estimated.
You are overwritting data each time even using array. You should create temporary object for storing value and then put them to item array.
$content = new \stdClass();
$content->item = array();
foreach($data as $key => $val) {
$itemVal = new \stdClass();
$itemVal->Value = $val;
$content->item[] = $itemVal;
}
I have this array
Array (
[0] => stdClass Object (
[id] => 252062474)
[1] => stdClass Object (
[id] => 252062474)
[3] => stdClass Object (
[id] => 252062474)
)
I need echo all of id's
I tried,
foreach($result as $item) {
echo $item->id;
}
but no luck
I try json_decode()
again no luck I use php 5.5.8
I know this work
echo $item[0]->id;
but i don't how many index is there
any idea?
Maybe you are confused on foreach(). If this works:
echo $item[0]->id;
Then you would need:
foreach($item as $result) {
echo $result->id;
}
Try this-
Code
foreach($result as $p) {
echo $p['id'] . "<br/>";
}
Output
252062474
252062474
252062474
This array could be looped through and data could be retrieved. As you are saying its not working I have added the following code to illustrate how it works right from generating the array for you.
// generating an array like you gave in the example. Note that ur array has same value
// for all the ids in but my example its having different values
$arr = array();
$init = new stdClass;
$init->id = 252062474 ;
$arr[] = $init;
$init = new stdClass;
$init->id = 252062475 ;
$arr[] = $init;
$init = new stdClass;
$init->id = 252062476 ;
$arr[] = $init;
print_r($arr);
The above array is same as yours
Array ( [0] => stdClass Object ( [id] => 252062474 )
[1] => stdClass Object ( [id] => 252062475 )
[2] => stdClass Object ( [id] => 252062476 )
)
Now the following code will loop through and get the data as
foreach($arr as $key=>$val){
echo $key.' ID is :: '.$val->id;
echo '<br />';
}
The output will be
0 ID is :: 252062474
1 ID is :: 252062475
2 ID is :: 252062476
Try this
foreach($result as $item) {
$item = (array)$item;
echo $item['id'];
}
