Insert Spaces

[Riddler]

Anyone have an idea about how I could go about writing a function that
would simply insert a character inbetween each character in a string?

For instance:

HELLO WORLD

would turn into:

H E L L O W O R L D

My brain hurts from thinking about this one but I'm stumped.

Thanks!

Tested:

<?php
function addspaces( $str ) {
$temp = array();
for ( $i = 0; $i < strlen( $str ); $i++ ) {
$temp[$i] = $str[$i].' ';
}
$temp = implode( '', $temp );
$temp = str_replace( ' ', '&nbsp;&nbsp;', $temp );
return $temp;
}
print addspaces( 'testing testing 123' );
?>

You can do this with a simple regular expression replacement. See the
online manual for the Perl-compatible Regular Expression functions:

php$ php -r 'echo preg_replace("/(.)/", "$1 ", "HELLO WORLD"), "\n";'
H E L L O W O R L D
Ah! -- but that might have a final (unwanted?) space. Let me check:

php$ php -r 'echo "[", preg_replace("/(.)/", "$1 ", "HELLO WORLD"), "]\n";' [H E L L O W O R L D ]
So, I need to remove that last space:

php$ php -r 'echo "[", substr(preg_replace("/(.)/", "$1 ", "HELLO WORLD"), 0, -1), "]\n";'

[H E L L O W O R L D]
Ok now.

Happy Coding :-)

$text='Hello, world!';
echo rtrim(preg_replace('/(.)/', '$1 ', $text));

[H E L L O W O R L D ]

A lookahead assertion would solve this problem:

echo preg_replace("/(.)(?=\S)/", "$1 ", "HELLO WORLD");

Another way to skin this cat:

echo trim(chunk_split("HELLO WORLD", 1, " "));

You could achieve a similar effect without having to add extra spaces
by using the CSS property 'letter-spacing'
http://www.w3.org/TR/CSS21/text.html#spacing-props

e.g.
<span style="letter-spacing: 0.5em">HELLO WORLD</span>

or put the style declaration in an external stylesheet and assign it
via a class selector.

May take a bit of tweaking of the spacing value to get the exact effect
you want. Also not sure about support for this in all browsers.

preg_replace('`.(?!\z)`s','$0 ',$subject)

Inserting a space between letters has a different effect to
that of the letter-spacing property. Letter-spacing affects
inter-letter spacing, a matter of style. Excepting PRE
element content, contiguous spaces in text should collapse
into a single one; that is, two spaces one after the other
share the semantics of a single space.
Also not sure about support for this in all browsers.

Neither am I. But browsers may treat its value as 'normal',
regardless of its specified value.

HAGW!

The added benefit of this method is that search engines etc will index
the words correctly. (Unless of course the OP is trying to fool word
recognition software!)

....and also in the case where the spaced text was copied from the web
page to another document, it would contain the complete words without
the added spaces between letters.
