Go here and get charprobe http://www.dextronet.com/charprobe.php It's a super
utility to have.
Look up the hex code for a space, "/x20" as I recall.
Then pick a non-printable code that you like e.g., /x83 or a printable one that
users cannot enter.
Then simply preg_replace("%/x20+%", "/83", $string); //one or more spaces
If you want to preserve the number of spaces don't use "+".

I'm trying to create an advanced search feature for my site, and I have
it mostly working the way I want. I take whatever search term
($searchkey) that the user submits, explodes if off any spaces between
words, and then use that to search for each word separately.
$keys = explode(" ",$searchkey);
So the search phrase of:
Dog Cat Horse
would output :
Array
(
[0] => Dog
[1] => Cat
[2] => Horse
)
However, I would like to add the ability to have phrases in there
indicated by " marks. So, if the search phrase was this:
"Dog Cat" Horse
It would output:
Array
(
[0] => Dog Cat
[1] => Horse
)
My concept to solve this is right before I explode the keys as above, to
replace any spaces within " marks with a garbage string of characters
(say XXXXXXXXXX) using a regular expression, and then later replace it
back with a space. However, I suck at regular expressions and can't
figure it out.
Anyone have a way for me to accomplish this with a regular expression or
with another method?
