guys is that possible to calculate between (+,-,*,/) in multidimensional array?
example i have a multidimensional array in $menu_info with this following code :
array(3) {
[0]=>
array(5) {
["menu_order_id"]=>
string(3) "190"
["menu_name"]=>
string(13) "Golden Salmon"
["menu_variant"]=>
string(0) ""
["qty"]=>
string(1) "1"
["price"]=>
string(4) "15.4"
}
[1]=>
array(5) {
["menu_order_id"]=>
string(3) "191"
["menu_name"]=>
string(13) "Golden Salmon"
["menu_variant"]=>
string(0) ""
["qty"]=>
string(1) "1"
["price"]=>
string(4) "15.4"
}
[2]=>
array(5) {
["menu_order_id"]=>
string(3) "192"
["menu_name"]=>
string(13) "Golden Salmon"
["menu_variant"]=>
string(0) ""
["qty"]=>
string(1) "1"
["price"]=>
string(4) "15.4"
}
}
i want trying to calculate all of the price*qty like (15*1)+(15*1)+(15*1)
guys how to count the multidimensional array using math operator ?
thank you very much (:
p.s the length of array can be change.
You can try this:
$sum = array_sum(array_map(function($item) {
return $item['price']*$item['qty'];
}, $menu_info));
With some more explanation on your specific issue, I may be able to assist you in better alternatives.

Hello i have an array_dif function between 2 arrays and the result it's not as it should.I don't understand why it does not return the status as difference. First array is data second is row and the third is the result. In the result it should also be status because the value is different.
$result = array_diff($data,$row );
array(9) {
["scooter_id"]=>
string(6) "RO0001"
["battery_lvl"]=>
string(2) "80"
["lat"]=>
string(9) "44.312150"
["lng"]=>
string(9) "23.872900"
["alt"]=>
string(1) "0"
["speed"]=>
string(1) "0"
["status"]=>
string(1) "2"
["ip"]=>
string(14) "213.233.101.62"
["port"]=>
int(24600)
}
array(11) {
["battery_lvl"]=>
string(2) "80"
["nr_satelites"]=>
string(1) "1"
["lat"]=>
string(9) "44.312154"
["longi"]=>
string(9) "23.873007"
["alt"]=>
string(1) "0"
["speed"]=>
string(1) "0"
["status"]=>
string(1) "1"
["location"]=>
string(7) "romania"
["ip"]=>
string(14) "213.233.101.62"
["port"]=>
string(5) "24600"
["status_intermediar"]=>
string(1) "2"
}
array(3) {
["scooter_id"]=>
string(6) "RO0001"
["lat"]=>
string(9) "44.312150"
["lng"]=>
string(9) "23.872900"
}
array_diff checks only the values.
Because your 2nd array contains ["status_intermediar"]=> string(1) "2" it finds the value so it doesn't see it as a difference
If you want to check both keys and values you should use array_diff_assoc
Also if you want to find all the different values from BOTH arrays you should run it twice
$difference1=array_diff_assoc($array1,$array2);
$difference2=array_diff_assoc($array2,$array1);
array_dif is one way function ("Compares array1 against one or more other arrays and returns the values in array1 that are not present in any of the other arrays."- https://www.php.net/manual/en/function.array-diff.php).
If you want all diffs, you have to call it twice: array_dif($first, $second) and array_dif($second, $one) and optionally merge results.
$array_difference1 = array_merge(array_diff($array1, $array2),
array_diff($array2, $array1));
$array_differnce = array_merge(array_diff($array_difference1, $array3),
array_diff($array3, $array_difference1));
array(2) {
[0]=>
object(stdClass)#21 (7) {
["id"]=>
string(1) "1"
["title"]=>
string(7) "cvxzcvd"
["con"]=>
string(10) "gvsdvgsdfg"
["is_important"]=>
string(1) "1"
["date"]=>
string(3) "123"
["image"]=>
string(2) "55"
["cat_id"]=>
string(1) "1"
}
[1]=>
object(stdClass)#22 (7) {
["id"]=>
string(1) "2"
["title"]=>
string(4) "fsdf"
["con"]=>
string(9) "dfdsfvfds"
["is_important"]=>
string(1) "1"
["date"]=>
string(4) "5145"
["image"]=>
string(7) "5454124"
["cat_id"]=>
string(1) "2"
}
}
I passed this array into a view
$this->load->view('home/index',$news_data);
but I wanna use the data separately.
I mean if I wanna use the second title
or the second data.
how can I express that in the view
thanks
You can go like this:-
$news_data[1]->title;
$news_data[1]->data;
Store the array into variable like
$news_data['arr'] = { } ;
,and in view file access it by $arr;
print_r($arr);
I'm trying to combine two array in PHP with array_combine() function, but sometimes it working fine and sometimes it's not. I can't understand why it's working like this!
My Code:
var_dump($selectedDuretion);
var_dump($selectedDuretionType);
$combination = array_combine($selectedDuretion, $selectedDuretionType);
return $combination;
Expected OUTPUT:
array(4)
{
[0]=> string(1) "3"
[1]=> string(2) "12"
[2]=> string(1) "4"
[3]=> string(1) "3"
}
array(4)
{
[0]=> string(4) "days"
[1]=> string(4) "days"
[2]=> string(5) "weeks"
[3]=> string(5) "weeks"
}
{"3":"days","12":"days","3":"weeks","4":"weeks"}
Actual OUTPUT :
array(4)
{
[0]=> string(1) "3"
[1]=> string(2) "12"
[2]=> string(1) "4"
[3]=> string(1) "3"
}
array(4)
{
[0]=> string(4) "days"
[1]=> string(4) "days"
[2]=> string(5) "weeks"
[3]=> string(5) "weeks"
}
{"3":"weeks","12":"days","4":"weeks"}
The combination of arrays it shocking, I'll be thankful if anyone tell me why is this happening and how to solve it.
PHP Does not allow you to have duplicate indices in an array while JSON does allow you to have that for whatever reasons.
Since you are trying to convert PHP arrays to JSON your duplicate key gets eliminated. Hence you will have to manually build the JSON string.
$json="";
for($i=0;$i<count($selectedDuration);$i++)
{
$json.='"'.$selectedDuration[$i].'":"'.$selectedDurationType[$i].'",';
}
$json=rtrim($json,",");
$json="{".$json."}";
echo $json;
Output
{"3":"days","12":"days","4":"weeks","3":"weeks"}

I am making a mailing system, and my input is array of arrays, i need to combine them to one, i already aggregated based on the email.
input example:
array(2) {
[0]=>
array(15) {
["enabled"]=>
string(1) "1"
["file_size_bytes"]=>
string(6) "200122"
["email"]=>
string(21) "jon#gmail.com"
["content"]=>
string(34) "{"Notice":827,"co":3241,"Co":1555}"
}
[1]=>
array(15) {
["enabled"]=>
string(1) "1"
["file_size_bytes"]=>
string(6) "592024"
["email"]=>
string(21) "jon#gmail.com"
["content"]=>
string(97) "{"Co":388,"co":5564,"xml":2982,"CO":6,"Warning":1957,"warning":42,"Notice":13,"cO":9,"Connect":6}"
}
}
array(1) {
[0]=>
array(15) {
["enabled"]=>
string(1) "1"
["file_size_bytes"]=>
string(5) "19116"
["email"]=>
string(22) "kelly#gmail.com"
["content"]=>
string(8) "{"co":1}"
}
}
input array to the mail function should look like:
array(1) {
[0]=>
array(15) {
["enabled"]=>
string(1) "1"
["file_size_bytes"]=>
string(6) "200122"
["email"]=>
string(21) "jon#gmail.com"
["content"]=>
string(34) "{"Notice":827,"co":3241,"Co":1555}"
["enabled"]=>
string(1) "1"
["file_size_bytes"]=>
string(6) "592024"
["email"]=>
string(21) "jon#gmail.com"
["content"]=>
string(97) " {"Co":388,"co":5564,"xml":2982,"CO":6,"Warning":1957,"warning":42,"Notice":13,"cO":9,"Conne ct":6}"
}
}
array(1) {
[0]=>
array(15) {
["enabled"]=>
string(1) "1"
["file_size_bytes"]=>
string(5) "19116"
["email"]=>
string(22) "kelly#gmail.com"
["content"]=>
string(8) "{"co":1}"
}
}
its basically spouse to combine the two arrays that are in the same array.
how can i do that? thanks :)
The required outcome is not possible since you have duplicate keys in the array which won't be possible in PHP.
e.g.
["content"] => string(34) "{"Notice":827,"co":3241,"Co":1555}"
will be replaced by
["content"] => string(97) "{"Co":388,"co":5564,"xml":2982,"CO":6,"Warning":1957,"warning":42,"Notice":13,"cO":9,"Connect":6}"
You can do this simply using the array_merge function.
In their answer, Maarten suggests this is not possible because duplicate keys would be overwritten. However this only occurs when the keys aren't numeric. In your example above the keys of the first array are 0 and 1 and the second just 0. All numeric.
So all you need to do is:
array_merge($array1,$array2);
here is the obj :
array(2) {
[0]=> object(stdClass)#538 (9)
{
["term_id"]=> string(3) "152"
["name"]=> string(19) "Éducation physique"
["slug"]=> string(18) "education-physique"
["term_group"]=> string(1) "0"
["term_taxonomy_id"]=> string(3) "159"
["taxonomy"]=> string(11) "product_cat"
["description"]=> string(0) ""
["parent"]=> string(3) "123"
["count"]=> string(1) "3"
}
[1]=> object(stdClass)#540 (9)
{
["term_id"]=> string(3) "123"
["name"]=> string(5) "Sport"
["slug"]=> string(5) "sport"
["term_group"]=> string(1) "0"
["term_taxonomy_id"]=> string(3) "123"
["taxonomy"]=> string(11) "product_cat"
["description"]=> string(0) ""
["parent"]=> string(1) "0"
["count"]=> string(2) "49"
}
}
mam :
i try to get the value : [term_id] of 152. what i need it the "152" value in a variable. i try : $product_category->term_id it return "nothing"
and i try : $product_category['term_id'] it return "nothing"
How is the "proper" way to retreive value from object
thanks in advance !
If I'm reading you right, and $product_category is the entire variable, you have two objects in an array. So you'll need to tell PHP which array item you're after before trying to access the object.
Something like $product_category[0]->term_id should work.
Here is another solution :
Convert this object to an array using json_decode, then get the values from array
$array = json_decode($json_string, true);
$term_id = $array[0]['term_id'];
OR to get both values :
foreach($array as $val){
echo $val['term_id'];
}
