RE: [PHP] Reg ex help-Removing extra blank spaces before HTML output

[Jack Dempsey]

true...he didn't mention newlines though so i left those out...also, "since
PHP 4.0.4 $n [meaning $1], being the preferred one." you also don't need
double quotes and since + means 1 or more, i'd save myself some typing
$input = preg_replace('/(\s|\n)+/',"$1",$input);
of course since you're now matching and replacing it'll take longer than a
straight substitution, although i doubt the files you're scanning are big
enough to notice

Hello,

The example Jack gave you will clear up spaces well, though to get both
newlines and spaces into one:

$input = preg_replace("/([ ]|\n){1,}/", "\\1", $input);
