Looping through JSON object properties

Looping through JSON object properties - php

The "name"s are accessed using $OBJ->top[0]->game->name etc... So just foreach over the "top" array:
foreach($OBJ->top as $object) {
echo $object->game->name;
}

Create an empty array, loop the objects top array and fill your empty array:
$allgames=array();
foreach($OBJ->method()->top as $ob){
$allgames[] = $ob->game->name;
}

When you load your JSON string into PHP you can use:
json_decode($string_of_json, true);
The true flag will load it into an array you can loop through using, for example, foreach.

How can I get the value of (e.g. url of the high stdClass object)?
Should I have to create first an array or can I access directly to this value? I don't know how to get the value of an object which is property from another object.
Thank in advance!

In your case:
echo $myObject->items[0]->id; //Outputs UC-lHJZR3Gqxm24_Vd_AJ5Yw
//or
echo $myObject->items[0]->snippet->thumbnails->default->url; //Outputs: https://yt3.ggpht.com/a/AGF-l79FVckie4j9WT-4cEW6iu3gPd4GivQf_XNSWg=s88-c-k-c0xffffffff-no-rj-mo
Object attributes must be refered with arrow (->) and array elements with brackets ([]).
items is an array, as you can see in your output.
In this example, I'm reading items from the main object ($myObject), the first index from items array (0), then it's property id;

Weird save to array in foreach in php

Something strange happens during saving into an array inside a foreach.
I'm getting unexpected results so I make this part of code for debuging.
$search_case = new stdClass();
$same_case = array ();
print_r($families);
foreach ($families as $key => $family) {
echo "<br/><br/>";
$same_case['aaaaa'.$key] = $this->search_benef->search_case($family, $search_case);
print_r($same_case);
}
The problem is that when I get function's results for $key = 1 it also change the data in table for $key = 0. To chek that I created aaaaa0 and aaaaa1 names for my table.
Bellow is print_r results:
First print_r I have 2 objects, IBRAHIM and MOHAMMAD
stdClass Object ( [0] => stdClass Object ( [focal] => stdClass Object ( [name] => RENAS [surname] => IBRAHIM [case_number] => 36343 ) [case] => 36343 ) [1] => stdClass Object ( [focal] => stdClass Object ( [name] => AZAD [surname] => MOHAMMAD [case_number] => 54944 ) [case] => 54944 ) )
Second print_r inside foreach loop, in the first loop I get results for IBRAHIM and in the second loop Ι get results for MOHAMMAD, but it removes results for IBRAHIM in aaaaa0.
Array ( [aaaaa0] => stdClass Object ( [old] => stdClass Object ( [hotel] => stdClass Object ( [focal] => stdClass Object ( [id] => 26 [name] => RENAS [surname] => IBRAHIM ) ) ) ) )
Array ( [aaaaa0] => stdClass Object ( [old] => stdClass Object ( [hotel] => stdClass Object ( [focal] => stdClass Object ( [id] => 22 [name] => AZAD [surname] => MOHAMMAD ) ) [athens] => stdClass Object ( [focal] => stdClass Object ( [id] => 24 [name] => AZAD [surname] => MOHAMMAD ) ) ) ) [aaaaa1] => stdClass Object ( [old] => stdClass Object ( [hotel] => stdClass Object ( [focal] => stdClass Object ( [id] => 22 [name] => AZAD [surname] => MOHAMMAD ) ) [athens] => stdClass Object ( [focal] => stdClass Object ( [id] => 24 [name] => AZAD [surname] => MOHAMMAD ) ) ) ) )
Can you explain why this happens? Which is the error?
-- EDIT --
I change my code and I remove 'search_case' function, but I face the same problem. The content changes. Below I paste my new code without the function.
$aaaaa = array ();
foreach ($families as $key => $family) {
echo "<br/><br/>Family->Case Number: " . $family->case;
$db_lists = array('athens' => 'athensDB', 'hotel' => 'hotelDB');
foreach ($db_lists as $key => $db_list) {
$remoteDB = $this->ci->load->database($key, TRUE);
$query = 'SELECT tb.id as id, name, surname FROM beneficiaries tb
left join _map_family_status tmfs ON tmfs.id=tb.family_status
where asylum_case = ' . $family->case . ' AND family_status = 1 GROUP BY asylum_case';
$focal = $remoteDB->query($query)->row();
if ($focal) {
$search_case->old->$key->focal = $focal;
}
}
echo '<br/> '.$family->case.' <br/> ';
$aaaaa[$family->case] = $search_case;
echo "<pre>";
print_r($aaaaa);
echo "</pre>";
}
return $aaaaa;
But the results are dissapointing. Array[36343] content changes with the second loop's content. Below I paste "print_r" results for the two loops.
Family->Case Number: 36343
Array (
[36343] => stdClass Object (
[old] => stdClass Object (
[hotel] => stdClass Object (
[focal] => stdClass Object (
[id] => 26

[surname] => IBRAHIM
)
)
)
)
)

How can I merge this array or remove a key

Below is an example of the array I have compiled so far. I am generating the array from a facebook graph api call and want to remove the Array wrapping each object so I just have one list under the data Array. Preferably I need a dynamic solution as their could be more than one [0] => Array, [1] => Array and so on.... in each API request.
stdClass Object
(
[data] => Array
(
[0] => Array
(
[0] => stdClass Object
(
[id] => 21744379694_10154626935079695
[created_time] => 2016-10-16T06:29:28+0000
[from] => stdClass Object
(
[name] => Tony Hawk
[id] => 21744379694
)
)
)
[1] => Array
(
[0] => stdClass Object
(
[id] => 50043151918_10154176205946919
[created_time] => 2016-10-15T20:04:22+0000
[from] => stdClass Object
(
[name] => GoPro
[id] => 50043151918
)
)
)
)
)
I would like the array to look like this ultimately. What is the best approach here?
stdClass Object
(
[data] => Array
(
[0] => stdClass Object
(
[id] => 21744379694_10154626935079695
[created_time] => 2016-10-16T06:29:28+0000
[from] => stdClass Object
(
[name] => Tony Hawk
[id] => 21744379694
)
)
[1] => stdClass Object
(
[id] => 50043151918_10154176205946919
[created_time] => 2016-10-15T20:04:22+0000
[from] => stdClass Object
(
[name] => GoPro
[id] => 50043151918
)
)
)
)

Assuming your data is stored in a variable $data, you can do this:
foreach($data->data as &$el) {
$el = $el[0];
}
Now the wrapping arrays have been removed.
See it run on eval.in

You can use this:
if ($data && $data->data){ $new = array_values($data->data); }

Freshbooks API show details

I am using the php library from here and I have a small problem.
To get some info for a invoice 118868, I can do this
<?php
$invoice_id=118868;
$invoice=$freshbooks->invoiceGet($invoice_id);
print_r($invoice);
?>
This is the output for print_r
Class Object ( [#attributes] => stdClass Object ( [status] => ok ) [invoice] => stdClass Object ( [invoice_id] => 00000219023 [estimate_id] => stdClass Object ( ) [number] => 8822 [client_id] => 83 [contacts] => stdClass Object ( [contact] => stdClass Object ( [contact_id] => 0 ) ) [recurring_id] => stdClass Object ( ) [organization] => Jimmy Thwart [first_name] => stdClass Object ( ) [last_name] => stdClass Object ( ) [p_street1] => stdClass Object ( ) [p_street2] => stdClass Object ( ) [p_city] => stdClass Object ( ) [p_state] => stdClass Object ( ) [p_country] => stdClass Object ( ) [p_code] => stdClass Object ( ) [po_number] => 10002 [status] => sent [amount] => 16.90 [amount_outstanding] => 16.90 [paid] => 0.00 [date] => 2013-01-31 00:00:00 [notes] => stdClass Object ( ) [terms] => Your slot can only be secured upon payment.

I hope the output can only be the URL and not this whole chunk of code.
Output wanted:
https://example.freshbooks.com/view/vgPb2TNGCR7n8JV
However, it lists all information of the invoice. How do I get only the invoice URL?

Well, using the output of your code, you can see what the elements of $invoice are. Use the one that you need.

Invoice is an instane of a class. You should treat it like all instances.
To get URL value you can do the next:
<?php
$invoice_id=118868;
$invoice=$freshbooks->invoiceGet($invoice_id);
print $invoice->url;
?>
or there's another possible value you're looking for:
<?php
$invoice_id=118868;
$invoice=$freshbooks->invoiceGet($invoice_id);
print $invoice->links->client_view;
?>
According to official API doc <url> is not supporting any more, so you should use <links> "element to provide your customers with direct links to the invoice for editing, viewing by the client and viewing by an administrator."

i need to get

668
of this i tried using foreach but no luck. anyone know how to do that using php an efficient way i mean without a loop
thank you

$obj->uv->current->value

Try this:
object->uv->current->display;
object->uv->current->value;
or use json_decode PHP function.

Try using json_decode() with the second parameter set to get it to output an array rather than an object structure.
`$outputArray = json_decode($inputString, true);
That will allow you to loop through it using foreach().

If you don't feel comfortable with objects you can simply put a "true" to the second parameter of json_decode().
json_decode($jsondata, true);
So you can access them as an array.

use json_decode($json, true) to get an associative arrays.

We Keep Coding

PHP, A popular general-purpose scripting language that is especially suited to web development.

Looping through JSON object properties - php

The "name"s are accessed using $OBJ->top[0]->game->name etc... So just foreach over the "top" array: foreach($OBJ->top as $object) { echo $object->game->name; }

Create an empty array, loop the objects top array and fill your empty array: $allgames=array(); foreach($OBJ->method()->top as $ob){ $allgames[] = $ob->game->name; }

When you load your JSON string into PHP you can use: json_decode($string_of_json, true); The true flag will load it into an array you can loop through using, for example, foreach.
