preg_split

[www.douglassdavis.com]

lets say I have a line of text with multiple spaces between each word..
I am not sure how many spaces. I would like to take the line of text,
and change it to put only one space between the words.

So, my idea was to split it on the spaces, then implode it with one
space between each word.

But, this doesn't work:

preg_split("/\\s*/","test test test test")

I would think that the regular expression would match multiple spaces,
and split on that, but instead it just breaks apart each character of
the string.

How can I break it apart so I get something like:

Array (
[0] => "test",
[1] => "test",
[2] => "test"
)

If you just want to replace multiple blanks between words try:
$string = preg_replace("/\s+/", " ", $string);

Replace * with +

$array = preg_split("/\s+/",$string);

I hadn't thought of that... makes sense.
