I want to separate a string that has no separation in an array
example
$s = "123";
$array=["1","2","3"];
I tried to use it as follows valores = (array) explode("",$IdNota); but he gives Warning: explode(): Empty delimiter in /var/www/html/Model/model.php on line 572
Someone knows how I do?

Hello. you can use a function php.
str_split Converts a string into an array.
https://www.php.net/manual/en/function.str-split.php
Ex:
$s = "123";
$valor = str_split($s);
print_r($valor);
It is worth remembering that the function str_split is not secure against multi-byte characters
do not understand. can explain what would be multi-byte characters?
Unicode characters. Test for str_split("pão").

You can do it like this:
$string="123";
for( $i=0; $i < strlen($string) ; $i++ ){
$array[$i]=$string[$i];
}
Go print something like this:
Array ( [0] => 1 [1] => 2 [2] => 3 )

You can use the function str_split to convert a string into an array.
Code Example:
<?php
$string = 123;
$split_length = 1;
$result = str_split ($string, $split_length);
?>
Upshot:
<?php
array (
0 => '1',
1 => '2',
2 => '3',
);
?>
You can test at that link.

A simpler solution is using the preg_split, as below:
$valores = preg_split('//u', $IdNota,-1, PREG_SPLIT_NO_EMPTY);

And do you really need it? PHP already accepts string indexing, treating it as an array. Depending on the case, you can already use
$s[0]... etc without having to do any operation - See working: https://ideone.com/hkmwt8– Bacco
