I want to remove all white spaces

Question

I have a string that is something like the example below,

assd *AA*the fox saw the outcome     *EAA*saassdsd

I want to remove the whitespace between AA and EAA using regex. Using the code below I can highlight everything between AA and EAA but I only want all the spaces to be highlighted. I believe this (.*) is grouping all the characters. Can someone point me in the right direction thanks?

 \*AA\*(.*)\*EAA\*

sorry should of said **white** space, which in regex lingo means "Matches any space, tab or newline character." — , Mar 17 '16 at 00:09
Your question is not clear, are you trying to remove the spaces btw `outcome and *EAA*` or all the whitespaces in the string? if the later, then I suggest you use the `preg_replace` function. — mendez7, Mar 17 '16 at 00:13

From your question, it appears that you want to remove all spaces from given string.

function sanitize($string)
{
    $re = "/^(.*?AA)(.*)(EAA.*)$/i";

    preg_match_all($re, $string, $matches);

    if($matches) {
        $p1 = $matches[1][0];
        $p2 = $matches[2][0];
        $p3 = $matches[3][0];

        $p2 = preg_replace("/\\s+/", "", $p2);

        $result = $p1.$p2.$p3;
        return $result;
    }
    return $string;
}

$str = "assd *AA*the fox saw the outcome     *EAA*saassdsd ";
print(sanitize($str))

This will render:

assd *AA*thefoxsawtheoutcome*EAA*saassdsd

This is really close except it removes the whitespace outside *AA* and *EAA* – purencool Mar 17 '16 at 01:05
I just tried \*AA\*(\s+)\*EAA\* and that did not highlight the whitespace – purencool Mar 17 '16 at 01:11
So what is your expectation? Remove spaces inside AA – Saleem Mar 17 '16 at 01:32
It never occurred to me to create three groups – purencool Mar 18 '16 at 06:31
