PHP - Sort array with first alphabet and convert it to key-CodePudding

So basically, I will have an array something like this..

<?php 

$array = array(
    'Actual Hours' => 'http://www.example.com/actual',
    'Algorithm' => 'http://www.example.com/algorithm',
    'Time Clock App' => 'http://www.example.com/time',
    
);

echo '<pre>';
print_r($array);
exit;

And I want the output something like this ...

Array
(
    [A] => [
        [Actual Hours] => http://www.example.com/actual
        [Algorithm] => http://www.example.com/algorithm
    ],
    [T] => [
        [Time Clock App] => http://www.example.com/time        
    ],
    
)

So basically I want something like this ..

As you can see, I want the first letter of the array key and want to sort it by adding a new key and sort it by that way.

I have researched it but haven't found any solution or suggestion.

Can someone guide me how can I achieve this.

Thanks

Here you go !


$array = array(
    'Actual Hours' => 'http://www.example.com/actual',
    'Algorithm' => 'http://www.example.com/algorithm',
    'Time Clock App' => 'http://www.example.com/time',

);

$new_array = [];
foreach( $array as $key => $value ) {
    $char = strtoupper(substr($key,0,1));
    if(!array_key_exists( $char, $new_array)) {
        $new_array[$char] = [];
    }
    $new_array[$char][$key] = $value;
}

$array = $new_array;

Loop, get the first letter 0 of the key string and add to that with the whole key:

foreach($array as $k => $v) {
    $result[strtoupper($k[0])][$k] = $v;
}
