Create an array inside array in PHP - php

Question

I have an imaging web service where I want to send as a JSon the results of a query in PHP to my application.
Basically, my result contains multiple results with each one having the same and following attributes
id
date
owner
extension
filename
I want to put them inside an array in such a way that each item's result is an array itself inside the bigger array just like the below image.
How can I accomplish this?

Answer 1

Do you need this?
$arrayInArray = array(
array("Thing1","Thing2"),
array("Thing3","Thing4")
);

Answer 2

After your query you can build an array the way you want (these are called multidimensional arrays) by using
$res = mysqli_query("SELECT `xx` FROM `xx`");
$images = array();
while($row = mysqli_fetch_array($res)) {
$images[] = $row;
}
return json_encode($images);

Answer 3

Say you have an image $image which is an array containing your attributes id, filename and so on.
Then just create array that hold all images and push it into that.
$images = [];
$images[] = $image; // Push image into images
// Or if you don't already have $image, you can also create and push at the same time
$images[] = [
'id' => 1,
...
];

Answer 4

You can generate array like this
<?php
$data=[
0=>[
'id'=>1,
'date'=>'3/3/2017',
'owner'=>'ownerName',
'extension'=>'yourExtension',
'filename'=>'YourFileName'
],
1=>[
'id'=>2,
'date'=>'3/3/2017',
'owner'=>'ownerName',
'extension'=>'yourExtension',
'filename'=>'YourFileName'
]
]；
$jsonData=json_encode($data)//convert into jsondata to send
?>
Then send this data.

Answer 5

This is called multidimensional array , simple syntax for your requirement is
Array(
[0] => Array
(
[id] => 1,
[date] => 2021,
[owner] => 'shebin',
[extension] => 'png',
[filename] => 'new'
)
)
In order to get the above structure you can simply use :
In this example ,
consider $images as multidimensional array so code will be like
$images[0]['id'] = 1 ;
$images[0]['date'] = 2021 ;
$images[0]['owner'] = 'shebin' ;
$images[0]['extension'] = 'png' ;
$images[0]['filename'] = 'new' ;
Instead of 0 you can use variable so you can create multiple set of this array
$images[$i]['id'] = 1 ;
