You can think about this two ways.

First, you can access the string as if it were an array (which you're attempting to do), e.g.

PHP Code:


			
$string= 'hello';

// display the first character in the string, at index 0

echo $string[0]; // 'h'

In your loop, you would refer to it with the [ ] brackets, not the { } braces. I haven't tested it, but I believe that actually tacks the numeric value of $i to the end of $string at that point in the loop. The other important factor, $char is not defined as an array. It's just a string as well, which is reassigned each time through the loop. I think you want something more like this

PHP Code:


			
// our string

$string= 'hello';

// an empty array

$charArray= array();

for ( $i=0; $i< strlen($string); $i++ ) {

  // assign each character in the string to an empty index

  $charArray[]= $string[$i];

}

// display the array values

print_r($charArray);
