Question

I have a string containing space-delimited words.

I want to reverse the letters in every word without reversing the order of the words.

I would like my string to become ym gnirts.

Answer 1

This should work:

$words = explode(' ', $string);
$words = array_map('strrev', $words);
echo implode(' ', $words);

Or as a one-liner:

echo implode(' ', array_map('strrev', explode(' ', $string)));
