Custom While in json array - php

Question

Its My PHP Code:
$res_media=mysql_query("SELECT * FROM mv_media");
$media = array();
while($resualt_media = mysql_fetch_assoc($res_media)) {
$media[]= $resualt_media['title'];
}
echo $media;
And Its My output:
["Test","Test","Test","Test","Test"]
I want Change it to this format :
["Test"],["Test"],["Test"],["Test"],["Test"]
I changed My Code to this code :
$res_media=mysql_query("SELECT * FROM mv_media");
$media = array();
while($resualt_media = mysql_fetch_assoc($res_media)) {
$media[]= [$resualt_media['title']];
}
echo $media;
Now My OutPut :
[["Test","Test","Test","Test","Test"]]
But I need This custom output:
[["Test"],["Test"],["Test"],["Test"],["Test"],["ItsMyCustomChild"]]
I want add Custom Child with out database!

Answer 1

You can change $media[] = [<value>] to $media[][] = <value> and it will work, because then you'll create a new array inside an array.

Answer 2

I would suggest this approach:
<?php
$input = json_decode('["Test","Test","Test","Test","Test"]');
$output = [];
array_walk($input, function($element) use (&$output) {
$output[] = [$element];
});
var_dump(json_encode($output));
Alternatively this can be simplified to just:
<?php
$data = json_decode('["Test","Test","Test","Test","Test"]');
array_walk($data, function(&$element) {
$element = [$element];
});
var_dump(json_encode($data));
The created array structure obviously is:
Array
(
[0] => Array
(
[0] => Test
)
[1] => Array
(
[0] => Test
)
[2] => Array
(
[0] => Test
)
[3] => Array
(
[0] => Test
)
[4] => Array
(
[0] => Test
)
)
Which, if you again json_encode() it, results in the desired format:
string(46) "[["Test"],["Test"],["Test"],["Test"],["Test"]]"
The specific issue you are actually dealing with is not so much the creation of the desired structure, but that you are trying to modify the JSON string instead of the actual array you want to work with. That is why a call to json_decode() is used initially.

Answer 3

$res_media=mysql_query("SELECT * FROM mv_media");
$media = array();
while($resualt_media = mysql_fetch_assoc($res_media)) {
array_push($media,array($resualt_media['title']));
}
print_r $media;

Answer 4

You just need to change below line. and you will get your desired result.
$media[][]= $resualt_media['title'];
if you want to see what you get . you need to add json_encode() after the while.
like below
echo json_encode($media);
