@DiosDe your function wrong;
$random_index = random_int(0, $sizeof_array);
must be :
$random_index = random_int(0, $sizeof_array-1);
working version:
<?php
function random_int_shuffle ( array $array ): array
{
$array = array_values($array);
$result = [];
$skip_indexes = [];
$sizeof_array = count($array);
for ( $i = 0; $i < $sizeof_array; $i++ )
{
do
{
$random_index = random_int(0, $sizeof_array - 1);
} while ( in_array($random_index, $skip_indexes) );
$skip_indexes[] = $random_index;
$result[] = $array[$random_index];
}
return $result;
}
?>
