php Replacing multiple spaces with a single space
ereg-replace, formatting, php, regex, string-formatting
Solution
Use `preg_replace()` and instead of `[ \t\n\r]` use `\s`:
$output = preg_replace('!\s+!', ' ', $input);
From Regular Expression Basic Syntax Reference:
\d, \w and \s
Shorthand character classes matching digits, word characters (letters, digits, and underscores), and whitespace (spaces, tabs, and line breaks). Can be used inside and outside character classes.
Problem
I'm trying to replace multiple spaces with a single space. When I use `ereg_replace`, I get an error about it being deprecated. ``` ereg_replace("[ \t\n\r]+", " ", $string); ``` Is there an identical replacement for it. I need to replace multiple `" "` white spaces and multiple `nbsp` white spaces with a single white space.
