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 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!
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 an array that can have many values at any given point, what I would like to accomplish is to combine all the array indexes and form one index with my final value. Merge other values that are the same
Say I have the array result below
Array
(
[0] => stdClass Object
(
[component] => sodium chloride
[generic_results] => Average:=99.20%
)
[1] => stdClass Object
(
[component] => sodium chloride
[generic_results] => RSD:=0.54%
)
[2] => stdClass Object
(
[component] => sodium chloride
[generic_results] => n:=3
)
)
What I would like is something like this
Array
(
[0] => stdClass Object
(
[component] => sodium chloride
[generic_results] => Average:=99.20%,RSD:=0.54%, n:=3
)
)
I have tried array unique but its not working.
Example code generating the results:
$arr=array(
(object) array(
'component'=>'sodium chloride',
'generic_results'=>'Average:=99'
),
(object) array(
'component'=>'sodium chloride',
'generic_results'=>'RSD:=0.54'
),
(object) array(
'component'=>'sodium chloride',
'generic_results'=>'n:=3'
)
);
print('<pre>');
print_r($arr);
print('</pre>');
Any Suggestions for this problem?
Try this
$new = array();
foreach ($array as $obj){
// By setting the key you guarantee it being unique
$new[$obj->component][$obj->generic_results] = $obj->generic_results;
}
$new2 = array();
foreach ($new as $comp=>$arr){
$new2['component'][$comp] = implode(',',$arr);
}
This will return an array but you can (although its not always sufficient) then use json_decode(json_encode($new2), false) to convert it to the object. Hope that helps.
You can use array_reduce, which iterates over an array to combine all elements with a given callback function:
$result = array_reduce($arr, function($result, $item) {
if ($result === null) {
// initialize with first item
return [$item];
}
// add generic_results of current item to result
$result[0]->generic_results .= ',' . $item->generic_results;
return $result;
}
);

I have an object which contains an array, which contains an array, which contains an object:
stdClass Object
(
[path] => Array
(
[0] => Array
(
[0] => SimpleXMLElement Object
(
[0] => 44.6451471575972
)
)
)
)
What I need to turn that into is this:
stdClass Object
(
[path] => Array
(
[0] => Array
(
[0] => 44.6451471575972
)
)
)
Basically I need to get rid of that object, but save the value in that object. Using PHP, how do I do this?
EDIT: Here the code I am using to create the array:
$xml = simplexml_load_file('/Users/jasonburton/Sites/walkabout/csv-importer/xml/'.$old_route_id.'.xml');
$nodes = $xml->xpath('/markers/line/*');
$json = new stdClass;
$json->path = array();
foreach($nodes as $node){
foreach($node->attributes() as $index=>$value){
$values[] = $value;
if(count($values) == 2){
$json->path[] = array($values[0], $values[1]);
unset($values);
$values = array();
}
}
}
print_r($json);
$value is what contains the SimpleXMLObject that needs to be converted into the value.
Thanks!
Type cast $value with string: $values[] = (string)$value;
<root>
<gallery name="First"/>
<gallery name="Second"/>
<gallery name="Third"/>
</root>
I'm trying to rename multiple "name" attributes at once:
$rename = array();
foreach($_POST['name'] as $value) {
$rename[] = $value;
}
$objXML = new SimpleXMLElement(XML_FILE_NAME, null, true);
$gallery = $objXML->xpath('/root/gallery/#name');
print_r($gallery);
print_r($rename);
$objXML->asXML(XML_FILE_NAME);
Returns:
Array ( [0] => SimpleXMLElement Object ( [#attributes] => Array ( [name] => First ) ) [1] => SimpleXMLElement Object ( [#attributes] => Array ( [name] => Second ) ) [2] => SimpleXMLElement Object ( [#attributes] => Array ( [name] => Third ) ) )
Array ( [0] => First New [1] => Second New [2] => Third New )
How can I get php to save the New values back to the XML? Does it need another foreach loop? The code seems to be getting too complex already.
I'm trying this, but no dice:
foreach( $objXML->xpath('/root/gallery/#name') as $gallery ) {
$gallery = $_POST['name'];
}
Simplexml is buid to returns node only. That's weird, but '/root/gallery/#name' and '/root/gallery'.
These two queries
$aList = $objXML->xpath('/root/gallery/#name');
$bList = $objXML->xpath('/root/gallery');
will return the same instances
for($i=0, $count=count($aList); $i<$count; $i++) {
$a = $aList[$i];
$b = $aList[$i];
var_dump($a==$b); // true
}
So the only way for changing the attribute of a node is with the array syntaxe
foreach($aList as $node) {
$node['name'] = 'foo' . $i;
}
var_dump($objXML);
