What is the potential issue when using a string as an array in PHP?

When using a string as an array in PHP, the potential issue is that you cannot directly access individual characters using array syntax. To solve this issue, you can convert the string into an array of characters using the `str_split()` function. This will allow you to access individual characters as elements of an array. 

$string = "Hello";
$chars = str_split($string);

// Accessing individual characters
echo $chars[0]; // Output: H
echo $chars[1]; // Output: e
echo $chars[2]; // Output: l
echo $chars[3]; // Output: l
echo $chars[4]; // Output: o
