Zip Postal Code

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';

?>
