I was kind of hoping to find a function where I can swap values in a string, but I couldn't
find one, so I wronte one, here it is:
function str_swap($swp1,$swp2,$str)
{
srand ((double) microtime() * 1000000);
for($i=0;$i<32;$i++) $tmp .= rand();
str_replace($swp1,$tmp.$swp1.$tmp,$str);
str_replace($swp2,$swp1,$str);
str_replace($tmp.$swp1.$tmp,$swp2,$str);
return $str;
}
EXAMPLE:
$string = 'Bob went out with Sally.';
so str_swap('Bob','Sally',$string);
would produce:
'Sally went out with Bob.
