[RESOLVED] Whitespace and all that jazz

scrupul0us

I've been googling and searching through these boards for an answer but have yet to really find what i need

ive built this:

function noWhiteSpace ($string)
{
$string = str_replace(' ' , '', $string);
$string = str_replace('\n', '', $string);
$string = str_replace('\r', '', $string);
$string = str_replace('\t', '', $string);
return $string;
}

but it still doesnt work 100%... while visually the output looks great, when i view source i can see tons of whitespace and tabs that are still there

have a look at the user contributions here: http://uk2.php.net/trim
I think it has exactly what you need.

what user specifically? none of the posts jump out at me

actually this worked:

function noWhiteSpace ($string)
{
$string = str_replace('  ' , '', $string);
$string = preg_replace('/\n/', '', $string);
$string = preg_replace('/\r/', '', $string);
$string = preg_replace('/\t/', '', $string);
return $string;
}

This one:

I use this to remove leading, trailing and "more than one" space in between words.

$pat[0] = "/^\s+/";
$pat[1] = "/\s{2,}/";
$pat[2] = "/\s+\$/";
$rep[0] = "";
$rep[1] = " ";
$rep[2] = "";
$str = "  Words with  lots      of  spaces    ";
$str = preg_replace($pat,$rep,$str);
// Output
"Words with lots of spaces"

$str = preg_replace('/\s/', '', $str);

And the original probably didn't work because of the use of single-quoted strings instead of double-quoted.

or that... havent tested it, but it word seem that it would work
