After implementing database queries, I am getting the multi-dimensional array below.
Two Dimensional Array
Array
(
[0] => Array
(
[t1] => test1
)
[1] => Array
(
[t2] => test2
)
[2] => Array
(
[t3] => test3
)
[3] => Array
(
[t4] => test4
)
[4] => Array
(
[t5] => test5
)
)
but I want to convert it to a single dimensional array, like the format below:
One Dimensional Array
Array (
t1 => test1
t2 => test2
t3 => test3
t4 => test4
t5 => test5
)
How can I do this?

The array_merge() function merges one or more arrays into one array.
const arr = [ [ {"c": 1},{"d": 2} ], [ {"c": 2},{"d": 3} ] ]; We are required to write a JavaScript function that takes in one such array as the first and the only argument. The function should then convert the array (creating a new array) into array of objects removing nested arrays.
Multidimensional PHP Array to String Maybe in case you need to convert a multidimensional array into a string, you may want to use the print_r() function. This is also called “array with keys”. By adding “true” as its second parameter, all the contents of the array will be cast into the string. <?
I think you can use array_reduce() function. For example:
$multi= array(0 => array('t1' => 'test1'),1 => array('t2' => 'test2'),2 => array('t3' => 'test3'),3 => array('t4' => 'test4'));
$single= array_reduce($multi, 'array_merge', array());
print_r($single); //Outputs the reduced aray
You can use as follows :
$newArray = array();
foreach($arrayData as $key => $value) {
foreach($value as $key2 => $value2) {
$newArray[$key2] = $value2;
}
}
Where $arrayData is your DB data array and $newArray will be the result.
