Break the word in php letters

Question

I want to take a string from a form and then split it into an array of characters using PHP, for example:

$a = 'professor';
$b[0] == 'p';
$b[1] == 'r';
$b[2] == 'o';
.
.
.
.
.
$b[8] = 'r';

Answer 1

You do not need to do this. In PHP, you can access your characters directly from a string, as if it contained an array:

$var = "My String";
echo $var[1]; // Will print "y".

Answer 2

str_split($word);

This is faster than accessing $ word as an array.(And also better if you can iterate over it with foreach().) Documentation .
