PHP - Split a word into an array

Question

I have done a lot of googling and whatnot and cannot find what I am looking for ...

I am working on tightening authentication for my site. I decided to take the user credentials, and the hash / salt from them. Then save these values ​​in the database and in the user's cookies. I changed the script I found on the PHP website and it has been working fine so far. However, I noticed that when using array_rand it sequentially selects characters from a predefined string. I did not like this, so I decided to use shuffle in the array_rand'd array. It works great.

Further! I thought it would be wise to turn the password entered by the user into an array, and then combine it with my salt array! Well, I can’t turn the user password into an array. I want each character in their password to be an array entry. IE, if your password was "cool", the array would be, Array 0 => c 1 => o 2 => o 3 => l, etc. Etc. I tried a word to break a string and then explode it using the specified interrupt character, which did not work. I suppose I could do something with a for, strlen loop, and much more, but there should be a more elegant way.

Any suggestions? I am somehow at an impasse :( That's what I still have, I have not done this because I have not advanced any further than the explodey part.

$strings = wordwrap($string, 1, "|");
echo $strings . "<br />";
$stringe = explode("|", $strings, 1);
print_r($stringe);
echo "<br />";
echo "This is the exploded password string, for mixing with salt.<hr />";

Thank you very much:)

Thanks to PHP's unmanaged tweaking, if you treat the string as an array, php will do what you expect. For instance:

$string = 'cool';
echo $string[1]; // output 'o'.
