This is my PHP code. This will fetch the data from a MySQL database and store in an array.
So, initially I have this array
$array_init;
print_r($array_init);
Array (
[0] => Array ( [id] => 2 [class_name] => Jr KG )
[1] => Array ( [id] => 3 [class_name] => Sr KG )
[2] => Array ( [id] => 4 [class_name] => I )
[3] => Array ( [id] => 5 [class_name] => II )
[4] => Array ( [id] => 6 [class_name] => III )
[5] => Array ( [id] => 7 [class_name] => IV )
[6] => Array ( [id] => 8 [class_name] => V )
[7] => Array ( [id] => 9 [class_name] => VI )
[8] => Array ( [id] => 10 [class_name] => VII )
[9] => Array ( [id] => 11 [class_name] => VIII )
[10] => Array ( [id] => 12 [class_name] => IX )
[11] => Array ( [id] => 13 [class_name] => X )
)
I wanted a fast traversal while coding
So for faster coding
I wanted to create an associative array like this:
Array (
[2] => Jr KG )
[3] => Sr KG )
[4] => I )
[5] => II )
[6] => III )
[7] => IV )
[8] => V )
[9] => VI )
[10] => VII )
[11] => VIII )
[12] => IX )
[13] => X )
)
I tried this
foreach ($array_init as $row_class) {
$classes[] = [$row_class['id']=>$row_class['class_name']];
}
I got this
Array ( [0] => Array (
[2] => Jr KG )
[1] => Array ( [3] => Sr KG )
[2] => Array ( [4] => I )
[3] => Array ( [5] => II )
[4] => Array ( [6] => III )
[5] => Array ( [7] => IV )
[6] => Array ( [8] => V )
[7] => Array ( [9] => VI )
[8] => Array ( [10] => VII )
[9] => Array ( [11] => VIII )
[10] => Array ( [12] => IX )
[11] => Array ( [13] => X )
)
BTW, it's not a duplicate as both question and solution are different.
