This one is starting to get on my nerves. Still fairly new to arrays and objects.
I need to be able to pull out [id] in the numbered array, plus get access to the lonely snippet_count at the end.
I can do it if there is no top level container array using a foreach $a as $k => $v., (from an earlier SO question) but am struggling a level deeper. Thanks.
Array
(
[snippets] => Array
(
[0] => stdClass Object
(
[id] => 123456789
)
[1] => stdClass Object
(
[id] => 123456789
)
[2] => stdClass Object
(
[id] => 123456789
)
//and so on
)
[snippet_count] => 500
)
You can iterate over just the snippets array to get the IDs
$ids = array();
foreach ($array['snippets'] as $snippet) {
$ids[] = $snippet->id;
}
$count = $array['snippet_count'];
Is this what you're looking for?

So I want to delete an array element from a JSON array based on an id in a sub-array. I know it sounds weird. Here's an example of the array. I want to delete the entire array [0] based on the [dealer][id] array where the [id] = 20220 in this example.
Array
(
[results] => Array
(
[offset] => 1
[length] => 15
[data] => Array
(
[0] => Array
(
[dealer] => Array
(
[id] => 20220
[name] => apple
)
)
)
)
}
In reality there are a lot more elements in the [results] array. I'm not sure how to go about it.
Any help is greatly appreciated!
Loop thru data key first then check if dealer id matches the searched id
$id = 20220;
foreach ($array['results']['data'] as $key => $value) {
if ($value['dealer']['id'] == $id) {
unset($array['results']['data'][$key]);
}
}
use array_filter,
$array['results']['data'] = array_filter($array['results']['data'], function($v){return $v['dealer']['id'] != 20220;});
I would like to replace a value within the path array and I'm quite stuck for a while. So here is what I got.
My array:
// $myArr
Array
(
[0] => stdClass Object
(
[doc] => stdClass Object
(
[path] => Array
(
[0] => Bob
[1] => pictures
[2] => food
)
)
)
[1] => stdClass Object
(
[doc] => stdClass Object
(
[path] => Array
(
[0] => Alice
[1] => pictures
[2] => vacations
[3] => rome
)
)
)
)
PHP code:
for ($i=0; $i < count($myArr) ; $i++) {
$search = array($old_name); // pictures
$replace = array($new_name); // test
$result = str_replace($search, $replace, $myArr[$i]->doc->path);
}
Result:
It only changes one array and gives me a hint on my str_replace line. Both, $search and $replace are of type array and I know that I need to access elements in an array via array notation -> $item['price'] for example. That is not what is wrong here right?
Notice: Trying to get property of non-object in ...

[1] => test
[2] => food
)
1) Do you see why he only modifies the last object so to speak?
2) Why is he giving me a Notice whereas I don't violate type conventions in my opinion?
Your code is working fine on my end, however..
I think the problem is in your $result variable. With every iteration, you are overwriting the last written value in the array.
You have to either use that $result variable directly, or replace $result by $myArr[$i]->doc->path. That way you can use the $myArr with the rewritten values.
I don't know what to do to get this done what would like to do. I tried multiple approaches, e.g. I used array_map, array_walk, nested foreach loops with get_object_vars and I worked with json_decode/encode and so on. I always come a little bit further but never reach my goal and I would like to get some guidance from you
Basically when you see the array below, how would you proceed when you want to change some value in the path array for multiple values in the array itself?
My questions:
1) Is it right that I must convert both nested objects to an array first or is this not nesessary to do this? I mean I always get some type conversion error which tells me that I either have everything as an object or array. Is this right?
2) If this mistery is solved, which php array function is the appropriate one to change values in an array(/object)? As I have written above, I tried so many and I don't see the trees in the woods anymore. Which one do you suggest to me to use in a foreach loop?
Array
(
[0] => stdClass Object
(
[doc] => stdClass Object
(
[path] => Array
(
[0] => Bob
[1] => pictures
[2] => food
)
)
)
[1] => stdClass Object
(
[doc] => stdClass Object
(
[path] => Array
(
[0] => Alice
[1] => pictures
[2] => vacations
[3] => rome
)
)
)
)
I would suggest that,
you create an array with keys as new path and value as old path (
path to be replaced).
Loop you path array and check if it is available in above defined array.
If available replace it with key of above defined array.
For example
// array defined as point 1
$change_path_array= array('pics'=>'pictures','meal'=>'food');
// $array is your array.
foreach ($array as $value) {
// loop you path array
for($i=0;$i<count($value->doc->path);$i++){
// check if the value is in defined array
if(in_array($value->doc->path[$i],$change_path_array)){
// get the key and replace it.
$value->doc->path[$i] = array_search($value->doc->path[$i], $change_path_array);
}
}
}
Out Put: picture is replaced with pics and food with meal
Array
(
[0] => stdClass Object
(
[doc] => stdClass Object
(
[path] => Array
(
[0] => Bob
[1] => pics
[2] => meal
)
)
)
[1] => stdClass Object
(
[doc] => stdClass Object
(
[path] => Array
(
[0] => Alice
[1] => pics
[2] => vacations
[3] => rome
)
)
)
)
You can modify the code to check casesensitive.
Example of changing all pictures to photos:
$doc1 = new \stdClass;
$doc1->doc = new \stdClass;
$doc1->doc->path = array('Bob', 'pictures', 'food');
$doc2 = new \stdClass;
$doc2->doc = new \stdClass;
$doc2->doc->path = array('Alice', 'pictures', 'vacations', 'rome');
$documents = array($doc1, $doc2);
/* change all 'pictures' to 'photos' */
foreach ($documents as &$doc) {
foreach ($doc->doc->path as &$element) {
if ($element == 'pictures') {
$element = 'photos';
}
unset($element);
}
unset($doc);
}
print_r($documents);
You can do it like this:
for($i = 0; $i < count($arr); $i++){
$path_array = $arr[$i]->doc->path;
// do your modifications for [i]th path element
// in your case replace all 'Bob's with 'Joe's
$path_array = array_map(function($paths){
if($paths == 'Bob') return 'Joe';
return $paths;
}, $paths_array);
$arr[$i]->doc->path = $path_array;
}
I have a stdclass object as shown below:
stdClass Object
(
[text] => Parent
[values] => Array
(
[0] => stdClass Object
(
[id] => /m/0c02911
[text] => Laurence W. Lane Jr.
[url] => http://www.freebase.com/view/m/0c02911
)
)
)
I iterate over multiple such objects, some of which have
stdClass Object
(
[text] => Named after
[values] => Array
(
[0] => stdClass Object
(
[id] => /m/0c02911
[text] => Stanford
[url] => SomeURL
)
)
)
I was wondering how I would access the "values" object if it comes after a "text" that has "Parent" as its value?
there are serveral ways to turn it to array:
First Solution:
$value = get_object_vars($object);
Second Solution:
$value = (array) $object;
Third Solution
$value = json_decode(json_encode($object), true);
to get value of converted array
echo $value['values']['0']['id'];
The alternate way to access objects var without convert the object, try
$object->values->{'0'}->id
Expanding (or rather minimalizing) upon answer by Somwang Souksavatd, I like accessing Object values like this:
echo get_object_vars($object)['values']['0']['id'];
I had the same issue, still not so sure why but I was able to get it working using this workaround:
$k2 ="1";
$elements = json_decode('{"id":"1","name":"User1"}');
//$elements['id'] == $k2; //****Not Working
$tmp = (object)$elements;
$tmp = $tmp ->id; //****Working
//$tmp =$elements['id'] ; //****Not Working
return $tmp == $k2;
I have to say that sometimes accessing the element as array works and some times not,(On PHP7 it worked for me but on PHP5.6 it didn't).
$elements can be Array to but I chose to demonstrate with json string.
I hope this helps somehow !!!
$Obj=stdClass Object
(
[text] => Named after
[values] => Array
(
[0] => stdClass Object
(
[id] => /m/0c02911
[text] => Stanford
[url] => SomeURL
)
)
)
$Values= $result->values;
$Item = $Values[0];
$id=$Item->id;
$text = $Item->text;
$url=$Item->url;
I'm doing the same thing and all I did was this;
<?php
$stdObject = json_decode($stdClassObject);
print $stdObject->values[0]->id;
this can help you accessing subarrays in php using codeigniter framework
foreach ($cassule['tarefa'][0] as $tarefa => $novo_puto_ultimos_30_dias) {
echo $novo_puto_ultimos_30_dias;
What you are looking for is the Object['values'][0]: 'values' is the keymap just like 'text', and [0] is the index inside that array you wish to access. so if you would like to get the id deep in the nest, you'd have to do something like
Object['values'][0]['id']
or
Object['values'][0]->id
which should give you /m/0c02911. But I have no idea how you are doing your loop, so you will have to adjust it to your needs and place proper variables where they need to go in that code in your loop. Not exactly sure which language you are working with.
This is what I want but cant figure out how to.
$a is this array
PHP Code:
Array
(
[0] => stdClass Object
(
[id] => i1
[cat] => Test1
)
[1] => stdClass Object
(
[id] => i2
[cat] => Test2
)
[2] => stdClass Object
(
[id] => i3
[cat] => Test3
)
[3] => stdClass Object
(
[id] => i4
[cat] => Test4
)
}
This is the array and it has those std classes associated with it. What I am trying to do is to combine all the "cat" names into one array variable.
I want to make $categories an array with all these "cat" as the array values.
How can I do that ?
array_map($a, function(stdClass $o) { return $o->cat; });
A simple way is just to loop over the array, grabbing the values that you want. There are other, fancier ways of doing the same but I like to keep it simple.
$categories = array();
foreach ($a as $obj) {
$categories[] = $obj->cat;
}
Of course, if not all of the array items are that object then it might be worthwhile to check that the cat property exists (and that $obj is a stdClass!).
Simply loop through and create a new array...
<?php
$newArray = array();
foreach($a as $cat) {
$newArray[$cat->id] = $cat->cat;
}
var_dump($newArray);
