Hi I am using an explode statement to get individual words from a selection of words which i then search within my site for.
works fine unless a user types in words that have more than a double space between example
"first [space][space][space] second"
what i need tp do is trim the white space between these words, any idea how i do this?
thanks in advance

Why not replace multi-spaces before exploding?
Code: Select all
//for 2 spaces
str_replace(" ", " ", $q);
//for 3 spaces
str_replace(" ", " ", $q);
str_replace(" ", " ", $q);
// loop for n spaces
$q_array=explode(" ", $q);

Code: Select all
foreach ($array as $k => $value) {
if (trim($value)=='') {
// delete element with the index $k
}
}

Code: Select all
$clean_string = preg_replace('/\s+/', '', $string); //Just make the second parameter a single space to turn excess whitespace into a single space
taken from a very old post i had, well it was not that old - less than 1 year actually but it sure feels like a long time ago.
