As the title says I'm trying to display data here is my code
$mars_temperature = new MaasApi();
$data=$mars_temperature->getLatest();
var_dump($data);
echo $data['sol'];
error Fatal error: Cannot use object of type stdClass as array on the last line and here is var_dump:

Update:
Here is also the code for API : https://github.com/dbough/MaasApi/blob/master/MaasApi.php
To access object properties, use the object operator: ->.
echo $data->sol;
To echo the properties that you referenced in your comment, use:
echo $data->max_temp;
echo $data->min_temp;

Creating one array from another array in php [closed]
(2 answers)
Closed 6 years ago.
I have the following PHP array
array (size=14)
0 =>
object(stdClass)[39]
public 'department' => string 'BOOKS' (length=32)
public 'dep_url' => string 'cheap-books' (length=32)
public 'category' => string 'Sci-fi' (length=23)
public 'cat_url' => string 'sci-fi' (length=23)
1 =>
object(stdClass)[40]
public 'department' => string 'JEWELRY' (length=32)
public 'dep_url' => string 'cheap-jewels' (length=32)
public 'category' => string 'Rings' (length=23)
public 'cat_url' => string 'rings' (length=23)
2 =>
object(stdClass)[41]
public 'department' => string 'JEWELRY' (length=32)
public 'dep_url' => string 'cheap-jewels' (length=32)
public 'category' => string 'Earings' (length=23)
public 'cat_url' => string 'cheap-earings' (length=23)
As you can see its an array of departments with their categories, how can i merge the array to get something like the following:
array (size=14)
0 =>
object(stdClass)[39]
public 'department' => string 'BOOKS' (length=32)
public 'dep_url' => string 'cheap-books' (length=32)
innerarray[0] =
public 'category' => string 'Sci-fi' (length=23)
public 'cat_url' => string 'sci-fi' (length=23)
1 =>
object(stdClass)[40]
public 'department' => string 'JEWELRY' (length=32)
public 'dep_url' => string 'cheap-jewels' (length=32)
innerarray[0] =
public 'category' => string 'Rings' (length=23)
public 'cat_url' => string 'rings' (length=23)
innerarray[1] =
public 'category' => string 'Earings' (length=23)
public 'cat_url' => string 'cheap-earings' (length=23)
I want to merge the array by department with the least amount of loops.
I hope i am clear with my question, thanks for any help you can give!
It would be best if you had a department ID (a primary key) to use to identify duplicates, but in lieu of that you should use the department name and URL together to match them.
Something like this should work:
$output = [];
foreach ($array as $entry) {
// no department ID, so create one for indexing the array instead...
$key = md5($entry->department . $entry->dep_url);
// create a new department entry
if (!array_key_exists($key, $output)) {
$class = new stdClass;
$class->department = $entry->department;
$class->dep_url = $entry->dep_url;
$class->categories = [];
$output[$key] = $class;
}
// add the current entry's category data to the indexed department
$category = new stdClass;
$category->category = $entry->category;
$category->cat_url = $entry->cat_url;
$output[$key]->categories[] = $category;
}
This will give you an array of department objects which contains, each of which contains an array of category objects. It'll be indexed by a hash which you create manually in lieu of a department ID/primary key to use instead.
To remove those keys simply do:
$output = array_values($output);
I am trying to use Openstreetmap and PHP to point to a place on a map.
As you can see below, I retrieve a JSON array, but PHP returns a NULL value.
Note that my $url is a valid JSON (you can check it here).
<?
$url = 'http://nominatim.openstreetmap.org/search/Piazza%20Duomo%20Trento?format=json&addressdetails=1&limit=1&polygon_svg=1';
$html = file_get_contents($url);
$jsonout = json_decode($html);
echo $jsonout[0];
?>
What am I doing wrong?
What am I doing wrong?
First of all, your openning tag is not correct :
<? ----> <?php
Then, you cannot echo an array like that. Use var_dump on your array to see the structure.
When I try your code with the corrections, I got this :
array (size=1)
0 =>
object(stdClass)[1]
public 'place_id' => string '8577656' (length=7)
public 'licence' => string 'Data © OpenStreetMap contributors, ODbL 1.0. http://www.openstreetmap.org/copyright' (length=84)

In answer to your question, except for trying to output an array with the following statement
echo $jsonout[0];
Which will throw a Catchable fatal error: Object of class stdClass could not be converted to string
Everything is ok.
If this is about accessing the members of the json_decode return, see below
$jsonout is an array with one element,
that one element is an object, you can access its members like this
print $jsonout[0]->licence;
Which will output
Data © OpenStreetMap contributors, ODbL 1.0. http://www.openstreetmap.org/copyright
If you'd like an associative array, you can pass the second argument for json_decode, like this
$jsonout = json_decode($html,true);
print $jsonout[0]['display_name'];
Which will decode the json into an associative array and will display in a similar way
Piazza Duomo, Piazza del Duomo, centro storico Trento, Trento, TN, TAA, 38122, Italia
please use print_r() in place of echo
$url = "http://nominatim.openstreetmap.org/search/Piazza%20Duomo%20Trento?format=json&addressdetails=1&limit=1&polygon_svg=1";
$html = file_get_contents($url);
$jsonout = json_decode($html);
print_r($jsonout[0]);
and you will get your result.
or you can print $jsonout[0]["license"]
If I do the following in this view composer:
View::composer('product.edit', function($view)
{
$viewdata = $view->getData();
dd($viewdata);
});
I can see in the output that exists 'language_id', however I don't know how to retrieve it, since $viewdata['language_id'] will throw an exception.
How should I go about this?
Update:
The accepted answer led me to discover that when a presenter is involved in this operation, the model will be available in the offset, here is the final code:
View::composer('product.edit', function($view)
{
$data = $view->offsetGet('product')->toArray();
echo $data['language_id'];
exit;
});
You may try this:
$language_id = $view->offsetGet('language_id');
Following public methods are available in the $view object (An instance of Illuminate\View\View)
0 => string '__construct' (length=11)
1 => string 'render' (length=6)
2 => string 'renderSections' (length=14)
3 => string 'with' (length=4)
4 => string 'nest' (length=4)
5 => string 'withErrors' (length=10)
6 => string 'getEnvironment' (length=14)
7 => string 'getEngine' (length=9)
8 => string 'getName' (length=7)
9 => string 'getData' (length=7)
10 => string 'getPath' (length=7)
11 => string 'setPath' (length=7)
12 => string 'offsetExists' (length=12)
13 => string 'offsetGet' (length=9)
14 => string 'offsetSet' (length=9)
15 => string 'offsetUnset' (length=11)
16 => string '__get' (length=5)
17 => string '__set' (length=5)
18 => string '__isset' (length=7)
19 => string '__unset' (length=7)
20 => string '__call' (length=6)
21 => string '__toString' (length=10)
You may also try something like this:
if($view->offsetExists('language_id')) {
$language_id = $view->offsetGet('language_id');
}
Worth noting you can also access view data using the attribute syntax (at least starting Laravel 8):
$languageId = $view->product->language_id ?? null;
I have the following code:
$b = $br->b;
var_dump($b);
$iCountBlock = count($b);
Where b is a SimpleXMLElement object. The var dump outputs:
object(SimpleXMLElement)[16]
public 'blockID' => string '160999' (length=6)
public 'blockDesc' => string 'Description' (length=37)
public 'moduleID' => string '1' (length=1)
public 'pubID' =>
object(SimpleXMLElement)[18]
public 'contentID' => string '93305' (length=5)
public 'linkToPageID' =>
object(SimpleXMLElement)[19]
public 'moduleFunction' => string 'replaceHTML' (length=11)
public 'moduleVars' =>
object(SimpleXMLElement)[20]
public 'c' =>
object(SimpleXMLElement)[21]
public 'contentID' => string '93305' (length=5)
public 'contentType' => string '1' (length=1)
public 'description' => string 'new.usdish.com index redesign content' (length=37)
public 'content' =>
object(SimpleXMLElement)[22]
However, $iCountBlock gets set to 1... it doesn't appear to be counting all the public properties of the object as it should. I also tried using a foreach loop to loop over each property of b and it didn't even enter the loop.
foreach($b as $key => $val) { ... }
I'm kinda at a loss here, as I'm not sure what's going on. Any thoughts?
Form PHP 5.3 and higher SimpleXMLElement does use a count function for the length!
$count = $b->count();
In PHP before 5.3 you have to use the childern property for getting the count.
$count = count($b->children());

Sorry for the title, I couldn't find a better way to write it =/
I am receiving a error object called ErrorBase.
If there is only one error it will return me the following:
public 'ErrorBase' =>
public 'CODIGO_ERRO' => string '1' (length=1)
public 'MENSAGEM_ERRO' => string 'Autenticação Inválida' (length=24)
public 'TIPO_ERRO' => string 'Usuario' (length=7)
But if there is more than one error, it will return me a array of objects like this:
public 'ErrorBase' =>
array
0 =>
object(stdClass)[30]
public 'CODIGO_ERRO' => string '1' (length=1)
public 'MENSAGEM_ERRO' => string 'Autenticação Inválida' (length=24)
public 'TIPO_ERRO' => string 'Usuario' (length=7)
1 =>
object(stdClass)[31]
public 'CODIGO_ERRO' => string '002' (length=3)
public 'MENSAGEM_ERRO' => string 'teste 002' (length=9)
public 'TIPO_ERRO' => string 'tipo 002' (length=8)
2 =>
object(stdClass)[32]
public 'CODIGO_ERRO' => string '003' (length=3)
public 'MENSAGEM_ERRO' => string 'teste 003' (length=9)
public 'TIPO_ERRO' => string 'tipo 003' (length=8)
3 =>
object(stdClass)[33]
public 'CODIGO_ERRO' => string '004' (length=3)
public 'MENSAGEM_ERRO' => string 'teste 004' (length=9)
public 'TIPO_ERRO' => string 'tipo 004' (length=8)
How can I work with these situations?
How do I check if there is a array of objects or only a object?
Thanks in advance for any help.
Try... is_object() and is_array()
is_array($variable) returns true if $variable contains an array, and false otherwise.
Use is_array() :
if (is_array($this->ERROR_BASE))
To test the class of an object :
if ($var instanceof ErrorBase) {
To test if it is an array :
if (is_array($var)) {
use gettype() to returns the vars type.
or use is_array/is_object to test for each
