I juste want to know how to read the value "status" in this PHP array:
Array
(
[0] => stdClass Object
(
[smsId] => 10124
[numberFrom] => +000
[numberTo] => +000
[status] => waiting
[date] => 20100825184048
[message] => ACK/
[text] => Test
)
[1] => stdClass Object
(
[smsId] => 10125
[numberFrom] => +000
[numberTo] => +000
[status] => waiting
[date] => 20100825184049
[message] => ACK/
[text] => Test 2
)
)
Thanks
Basically you have an array of objects. So you have to use a combination of array and object syntax to get your value:
$array[0]->status;
this breaks down into:
$object = $array[0]; // Array Syntax
$status = $object->status; // Object Syntax
$status = $array[0]->status; // Combined Array & Object Syntax
If you need to access each status in a loop, you do something like:
foreach($array as $obj){
$status = $obj->status;
}
$arr is the array you've got there.
for($i=0; $i<count($arr); $i++){
echo $arr[$i]->status;
}
Please take a look in the PHP Manual
You can do:
foreach($array as $arr) {
echo $arr->status;
}
If array variable is $arr
$arr[0]->status;
$arr[1]->status;

I've got an object, containing an array of objects, containing an array of values:
stdClass Object (
[devices] => Array (
[0] => stdClass Object (
[location] => 1
[delegate] =>
[type] => 1
[id] => 1234
[IP] => 1.2.3.4
[name] => host1
[owner] => user6
[security] => 15
)
[1] => stdClass Object (
[location] => 2
[delegate] =>
[type] => 1
[id] => 4321
[IP] => 4.3.2.1
[name] => host2
[owner] => user9
[security] => 15
)
)
)
I want to extract just the id and name into an array in the form of:
$devices['id'] = $name;
I considered using the array_map() function, but couldn't work out how to use it... Any ideas?
This will generate you a new array like I think you want
I know you says that delegate is an object but the print does not show it that way
$new = array();
foreach($obj->devices as $device) {
$new[][$device->id] = $device->name;
}
Would something like this not work? Untested but it cycles through the object structure to extract what I think you need.
$devices = myfunction($my_object);
function myfunction($ob){
$devices = array();
if(isset($ob->devices)){
foreach($ob->devices as $d){
if(isset($d->delegate->name && isset($d->delegate->id))){
$devices[$d->delegate->id] = $d->delegate->name;
}
}
}
return($devices);
}
Im usually using this function to generate all child and parent array stdclass / object, but still make key same :
function GenNewArr($arr=array()){
$newarr = array();
foreach($arr as $a=>$b){
$newarr[$a] = is_object($b) || is_array($b) ? GenNewArr($b) : $b ;
}
return $newarr;
}
I need help :)
I've to code a script that, cycling through an array inside an array , delete an element if in XXX field there isn't value (is NULL ).
My array is:
Array (
[idCampaign] => 3
[idIT] => 322
[recipients] =>Array (
[0] => stdClass Object ( [name] => minnie [email] => blabla#gmail.com [XXX] => )
[1] => stdClass Object ( [name] => [email] => fddd#gmail.it [XXX] => 0.88451100 )
) ) [date] => MongoDate Object ( [sec] => 1468503103 [usec] => 0 ) )
In this example the item [0] has no value in XXX value so my output array will be:
Array (
[idCampaign] => 3
[idIT] => 322
[recipients] =>Array (
[1] => stdClass Object ( [name] => [email] => fddd#gmail.it [XXX] => 0.88451100 )
) ) [date] => MongoDate Object ( [sec] => 1468503103 [usec] => 0 ) )
i hope that you can help me :)
You could use a nested foreach() Loop to cycle through the Data and then perform some tests, which on failing, guarantees that it is safe to unset the pertinent variable. Here's how:
<?php
// WE SIMULATE SOME DATA TO POPULATE THE ARRAY, ONLY FOR TESTING PURPOSES
$objDate = new stdClass();
$objRez1 = new stdClass();
$objRez2 = new stdClass();
$objRez1->name = "minnie";
$objRez1->email = "blabla#gmail.com";
$objRez1->XXX = null;
$objRez2->name = null;
$objRez2->email = "fddd#gmail.it";
$objRez2->XXX = 0.88451100;
$objDate->sec = 1468503103;
$objDate->usec = 0;
// IN THE END WE NOW HAVE A SAMPLE ARRAY (SIMULATED) TO WORK WITH.
$arrData = array(
'idCampaign' => 3,
'idIT' => 322,
'recipients' => array(
$objRez1,
$objRez2
),
'date' =>$objDate,
);
// LOOP THROUGH THE ARRAY OF DATA THAT YOU HAVE
// NOTICE THE &$data IN THE LOOP CONSTRUCT...
// THIS IS NECESSARY FOR REFERENCING WHEN WE UNSET VARIABLES WITHIN THE LOOP
foreach($arrData as $key=>&$data){
// SINCE THE XXX KEY IS STORED IN THE 'recipients' ARRAY,
// WE CHECK IF THE CURRENT KEY IS 'recipients' & THAT $data IS AN ARRAY
if($key == "recipients" && is_array($data)){
// NOW WE LOOP THROUGH THE DATA WHEREIN THE 'XXX' KEY LIVES
foreach($data as $obj){
// IF THE VALUE OF THE XXX KEY IS NULL OR NOT SET,
// WE SIMPLY UNSET IT...
if(!$obj->XXX){
unset($obj->XXX);
}
}
}
}
var_dump($arrData);
You can verify the Results HERE.
Hope this could offer you a little tip on how to implement it rightly on your own...
This should do the job
foreach($arrayOfObjects as $index => $object){
if(!isset($object->xxx) || empty($object->xxx)){
unset($arrayOfObjects[$index]);
}
}
So, I have following db result:
Array
(
[0] => stdClass Object
(
[id] => 1
[user] => 1
[img] => 2016/02/img_8488.jpg
[url] => /p=?44
[sent_date] => 2016-02-13 00:00:00
)
[1] => stdClass Object
(
[id] => 2
[user] => 185
[img] =>
[url] => /?p=54
[sent_date] => 2016-02-06 00:00:00
)
)
How would I remove [id] and [sent_date] from the query result?
I am not sure if I am using unset right.
unset($results[0]['id']);
$reindex = array_values($results);
$objectarray = $reindex;
Instead of removal or unset you can create a new array;
$i = 0;
$newResult = array();
foreach($result as $value){
$newResult[$i]["user"] = $value->user;
$newResult[$i]["img"] = $value->img;
$newResult[$i]["url"] = $value->url;
$i++;
}
print_r($newResult);
$newResult will return the new array and your original array remains same you can use it if you need.
Or removal of indexes is must required than use unset inside the foreach loop as:
unset($value->id);
unset($value->sent_date);
Side note:
Also keep in mind you can not use it as $value["id"] becuase its a property not an array index.
Use unset($results[0]->id); and unset($results[0]->sent_date) instead and it should work. If you want to do this in all of the array objects:
for($i = 0; $i<sizeof($results); $i++)
{
unset($results[$i]->id);
unset($results[$i]->sent_date);
}
i have an extern JSON File and no problems to get Airline, Price, etc..
But how can i get [ACE] ?
[success] => 1
[data] => Array
(
[ACE] => Array
(
[0] => Array
(
[price] => 477
[airline] => AB
[flight_number] => 2434
[departure_at] => 2014-08-09T12:30:00Z
[return_at] => 2014-08-24T08:35:00Z
[expires_at] => 2014-04-03T22:46:17Z
)
)
$foo = $json['data']['ACE']; should do it.
Unless you want to get the key from the $data array, in which case:
foreach ($json['data'] as $k=>$v) {
$foo = $k; // this is 'ACE'.
break;
}
Edited as per comment.
['ACE'] is an array?
Your getting the data from it starting with the first - [0]
Then the ['price'] of the first one?
I'm having some problems getting the array in these objects. When I print_r(), the following code is printed. $message_object is the name of the object.

I'm trying to get the id arrays out of the objects with a foreach:
foreach($message_object->data->id AS $id) {
print_r($id);
}
The following reply is sent:
SimpleXMLElement Object ( [0] => 65233 ) SimpleXMLElement Object ( [0] => 65234 )
How do I get the value of [0] or am I going about this wrong? and is there a way to loop though the results and get the object keys?
I have tried to echo $id[0] but it returns no result.
When you use print_r on a SimpleXMLElement there comes magic in between. So what you see is not actually what is there. It's informative, but just not the same as with normal objects or arrays.
To answer your question how to iterate:
foreach ($message_object->data->id as $id)
{
echo $id, "\n";
}
to answer how to convert those into an array:
$ids = iterator_to_array($message_object->data->id, 0);
As this would still give you the SimpleXMLElements but you might want to have the values you can either cast each of these elements to string on use, e.g.:
echo (string) $ids[1]; # output second id 65234
or convert the whole array into strings:
$ids = array_map('strval', iterator_to_array($message_object->data->id, 0));
or alternatively into integers:
$ids = array_map('intval', iterator_to_array($message_object->data->id, 0));
You can cast the SimpleXMLElement object like so:
foreach ($message_object->data->id AS $id) {
echo (string)$id, PHP_EOL;
echo (int)$id, PHP_EOL; // should work too
// hakre told me that this will work too ;-)
echo $id, PHP_EOL;
}
Or cast the whole thing:
$ids = array_map('intval', $message_object->data->id);
print_r($ids);
Update
Okay, the array_map code just above doesn't really work because it's not strictly an array, you should apply iterator_to_array($message_object->data_id, false) first:
$ids = array_map('intval', iterator_to_array$message_object->data->id, false));
See also: #hakre's answer.
You just need to update your foreach like this:
foreach($message_object->data->id as $key => $value) {
print_r($value);
}
