I want to add a space to some output after every 4th character until the end of the string. I tried:

$str = $rows['value'];
<? echo substr($str, 0, 4) . ' ' . substr($str, 4); ?>

Which just got me the space after the first 4 characters.

How can I make it show after every 4th ?

You can use chunk_split [docs]:

$str = chunk_split($rows['value'], 4, ' ');


If the length of the string is a multiple of four but you don't want a trailing space, you can pass the result to trim.

[SOLVED] Need to add space after every 4th Character, Hi all I'm hoping this is an easy one for you. I have some numbers like But i need to add spaces after EVERY 4th Character, like this: Supposing that every input number that you will get is 12 character length, you can do this like that

Wordwrap does exactly what you want:

echo wordwrap('12345678' , 4 , ' ' , true )

will output: 1234 5678

If you want, say, a hyphen after every second digit instead, swap the "4" for a "2", and the space for a hyphen:

echo wordwrap('1234567890' , 2 , '-' , true )

will output: 12-34-56-78-90

Reference - wordwrap

Space after every 4th character and after 2nd if needed : regex, replace(/\d{4}(?=.)/g, '$& ');. first it removes the spaces already added or from previous formatting and adds new spaces. Sure, and that has already been answered incl. making visible that if a space is needed after each 4th character as well at the end of the string, this needs some addition. And a tab is not a space but I think you know. – hakre Aug 4 '12 at 10:41

Here’s a quick way to do this by inserting a blank row into your data after every Nth record. I realize it’s a bit of cluster bomb and I might have put a bit too much in it 🙁 To accomplish our task we’re going to need to add a helper column. Add a column to the right of your data.


$yourstring = "1234567890";
echo implode(" ", str_split($yourstring, 4))." ";

This should give you as output: 1234 5678 90

That's all :D

On way would be to split into 4-character chunks and then join them together again with a space between each part.

As this would technically miss to insert one at the very end if the last chunk would have exactly 4 characters, we would need to add that one manually (Demo):

$chunk_length = 4;
$chunks = str_split($str, $chunk_length);
$last = end($chunks);
if (strlen($last) === $chunk_length) {
    $chunks[] = '';
$str_with_spaces = implode(' ', $chunks);
