        for($i=0; $i <= $name_mainlen + 1; $i++) {
            echo $name[$i];
            $name[$i] = str_split($name[$i]);
            $namelen = count($name[$i]);
            echo $namelen . '<br/>';

            function spellname($x, $namelen) {
                for($i=0; $i <= $namelen; $i++) {
                    echo $x[$i] . '<br/>';
                }

get_num_of_names($name);

Answer 1

You’re defining a function in a loop. Your script should implode with a Function 'spellname' already defined error, if you’d activate error reporting.

A function is defined when it is encountered. If you place it in a loop, it will be defined on each iteration. Since you can’t define two functions with the same name, your script aborts with a fatal error.

Apart from that, there are much easier ways to do what you want to do:

$str = 'Hello World';
$words = explode(' ', $str);
$output = array();
foreach ($words as $word) {
    $output[] = join('<br />', str_split($word));
}
echo join('<br /><br />', $output);

Or, as a one-liner:

echo join('<br /><br />', array_map(create_function('$a', 'return join("<br />", str_split($a));'), explode(' ', $str)));

Or, even shorter with different approach (regards to @Long Ears):

echo join('<br />', str_replace(' ', '', str_split($str)));
