Let me know how can be done with php

You can use regular expressions to find [lowercase character][uppercase character] and insert a space:

$newstr = preg_replace('/([a-z])([A-Z])/s','$1 $2', $oldstr);

---

You might look into CakePHP's Inflector class for guidance (for example the humanize function).

---

Are they all camelCase like that? You can turn it into an array, then turn that into a string.

<?php
function splitCamelCase($str) {
  return preg_split('/(?<=\\w)(?=[A-Z])/', $str);
}

print_r(splitCamelCase("ZipPostalCode"));
?>

Edit: Disregard this - Mark's answer is better.

$new = preg_replace('/([a-z])([A-Z])/', '$1 $2', $old);

Use preg_replace()

$str = 'HelloThere';
$str= preg_replace('/(?<=\\w)(?=[A-Z])/'," $1", $str);
echo trim($str); //Hello There

---

<?php
//  It can be done as:
echo 'Country ','Name <br>';
echo 'Region ','Name <br>';
echo 'Zip ','Postal ','Code';

//   OR

echo 'Country ','Name <br> Region ','Name <br> Zip ','Postal ','Code';

?>
