),
)
Please help me how to array of inner array function
Thanks Regards
It seems that you are not processing the data retrieved from database, correctly.
We could help you more, only if you provide your code snippet here.
However you can transform your array by using following steps:
1) Initialize a new empty array named $output
2) Iterate your database result array in a 'for' loop
3) In 'for' loop, do operations to insert in $output array as per your desired format.
4) In the end, $output array is your desired array.

I want to combine my ordered products and display the order list.
Controller :
$orders = Order::where('customer_id', 1)->pluck('products');
print_r($orders);
This is what I receive:
Array (
[0] =>
[
{"id":3,"product_id":3,"size":"47","quantity":7,"name":"Simple Regular T-shirt","price":2200,"thumbnail":"Thumbnail_614291597.jpg"},
{"id":7,"product_id":4,"size":"47","quantity":8,"name":"Simple Regular Shirt","price":123,"thumbnail":"Thumbnail_91520734.jpg"}
]
[1] =>
[
{"id":9,"product_id":3,"size":"45","quantity":2,"name":"Simple Regular T-shirt","price":2200,"thumbnail":"Thumbnail_614291597.jpg"}
]
)
But I want.
Array (
[0] =>
[
{"id":3,"product_id":3,"size":"47","quantity":7,"name":"Simple Regular T-shirt","price":2200,"thumbnail":"Thumbnail_614291597.jpg"},
{"id":7,"product_id":4,"size":"47","quantity":8,"name":"Simple Regular Shirt","price":123,"thumbnail":"Thumbnail_91520734.jpg"},
{"id":9,"product_id":3,"size":"45","quantity":2,"name":"Simple Regular T-shirt","price":2200,"thumbnail":"Thumbnail_614291597.jpg"}
]
)
How I can do this?
I already tried a different way, but I can't do this. Firstly I was trying to convert it array and then use the array_marge() function for those arrays. but that array needs only two arrays but for my case, it is not specified how many arrays the user has given. And try to solve it with a loop (I just tried). I am new in this field.
You could try
$orders = Order::where('customer_id', 1)
->pluck('products')
->values()
->flatten(1);
The pluck will return a collection, flatten with a depth of 1 will remove the nesting. values will reset the keys to sequential - (it's not strictly necessary here)
Laravel Docs - Collections - Values
Laravel Docs - Collections - Flatten
Just add flatten() after applying the query (with ->get()):
$orders = Order::where('customer_id', 1)->get()->pluck('products')->flatten();
print_r($orders);
Side note:
Instead of print_r() You can use dump() to pretty print the output in your browser
$orders->dump(); //only dump
$orders->dd(); //dump and exit
I have an array as follows:
$aq=['jonathan','paul','andy','rachel'];
Then I have an array as follows:
$bq=['rachel','andy','jonathan'];
What I need is to use the ordering of the first array to sort my second array.
So for this instance, the resulting sorted array should be:
$cq=['jonathan','andy','rachel'];
I started working on a solution that uses the highest key as the top value (the head of the array) because what Im looking for is the top value but that ran into issues and seemed more like a hack so i think sorting is what im looking for.
Is there a simple function in php that can sort my data based on my first array and there respective positions in the array
please try this short and clean solution using array_intersect:
$aq = ['jonathan','paul','andy','rachel'];
$bq = ['rachel','andy','jonathan'];
$cq = array_intersect($aq, $bq);
var_export($cq);
the output will be :
array ( 0 => 'jonathan', 2 => 'andy', 3 => 'rachel', )
You'll have to use a custom sort function. Here we grab the keys of corresponding entries in the "ordering" array and use them to order the working array.
In this example, we give up (return 0) if the key doesn't exist in the ordering array; you may wish to customize that behavior, but this should give you the general idea.
$order = ['jonathan','paul','andy','rachel'];
$arrayToSort =['rachel','andy','jonathan'];
usort($arrayToSort,function($a,$b) use ($order){
if( ! array_key_exists($a,$order) ) return 0;
if( ! array_key_exists($b,$order) ) return 0;
if( array_search($a,$order) > array_search($b,$order)
return 1;
return -1;
});
I run a gaming server and it keeps some information in a database.
I run a MySQL query that pulls information like cargo_items (below).
How can I format this data properly in PHP? I'd like for it to be in a table. Is that possible? My knowledge of handing arrays like this is limited do to the complex nature. This is how the data is returned from the database.
Array
(
[0] => Array
(
[0] => Array
(
[id] => 2237
[cargo_weapons] =>
[
["MMG_02_black_F","","","",[],""],
["arifle_SDAR_F","","","",[],""],
["arifle_SDAR_F","","","",[],""],
["arifle_SPAR_03_khk_F","","","",[],""],
["LMG_Zafir _F","","","",[],""],
["MMG_02_black_F","","","",[],""],
["MMG_02_black_F","","","",[],""]
]
)
)
)
The output should be a table:
Weapons
-------
MMG_02_black_F
arifle_SDAR_F
arifle_SDAR_F
arifle_SPAR_03_khk_F
LMG_Zafir_F
MMG_02_black_F
MMG_02_black_F
Since you have multidimensional array, you need custom recursion function, or, in your specific case, you could use something like this:
function get_items($item, $key)
{
if(!empty($item) && $key=='cargo_weapons')
//your html table cells
echo "$item<br>";
}
array_walk_recursive($array, 'get_items');
array_walk_recursive
will do the job (this function returns true or false), but you can (ab)use it to display desired HTML too.
I have created a custom field named "sec1array" in my categories so that i can add an array, for example 1,2,3,4
I want to retrieve that array and output it in the loop, so I created this code.
$seconearray = array($cat_data['sec1array']);
$args = array(
'post__in' => $seconearray
);
However, it only seems to be outputting the first post in the array. Is it something to do with the way the comma is outputting?
If I print $seconearray it outputs correctly, example 1,2,3,4
What you are doing is storing a string value of "1,2,3,4" in your database which when you are trying to construct an array from it like array("1,2,3,4") you end up just assigning a single value to that new array. This is why it only contains a single value.
You need to store your value in a serializable format so it can be converted back to an array after you save it to the database. There are many ways to do this, I'm sure others will give more examples:
JSON encode it
json_encode(array(1,2,3,4)); // store this in your db
json_decode($cat_data['sec1array']); // outputs an array
Or, you can use PHP serialize
serialize(array(1,2,3,4)); // store this in your db
unserialize($cat_data['sec1array']); // outputs an array
If you want to keep your string, you can explode it:
explode(',', $cat_data['sec1array']); // outputs your array of 1,2,3,4.
Using any of these methods will work. Finally you'll end up with an example like:
$seconearray = explode(',', $cat_data['sec1array']);
$args = array(
'post__in' => $seconearray
);
Can you please help me extracting MySQL data in php array.
my sql:
SELECT count(*) as total, post_type as type FROM wp_posts group by post_type;
to php, like below:
<?php $total = array(5,7, .. , ..); $type = array('Page', 'Post', '..',..'); ?>
Array should come from database
Thanks :)
You can't get two separate arrays from single SQL query either you have to run the mysql query two times or Write a PHP code which gives you the desired result.
Your current query will give result as follow.
Array
(
[0] => Array
(
[total] => 5
[post_type] => Page
)
)
Now you have to traverse these array to create two separate arrays you want.
$total=array_column($result,'total');
$type = array_column($result,'post_type');
Above code will give you two separate arrays.
Thanks to Niet the Dark Absol for array_column, it looks more clean then traversing manually.
