I've got a string [not an array, it's a load of words stored in one string] and I'd like to put a comma after every word, although not putting one after the last word. I've got;
echo str_replace[' ', ', ', $stilltodo];
but that for some reason adds a space before the comma [and after too but that's right], and also one at the end too. How could I change it to work how I want.

Welcome to a short tutorial on how to add commas to numbers in PHP. Need to format and present a “nice-looking” number to the users? The common ways to add commas to numbers in PHP are:
- Use the
number_format[]function. For example,$num = number_format[12345.678, 2]; - Use regular expressions. For example,
$num = preg_replace["/\B[?=[\d{3}]+[?!\d]]/", ",", 12345.78]; - Manually split the number, add commas, and
combine them back.
$num = explode[".", 12345.78];$num[0] = implode[",", str_split[strrev[$num[0]], 3]];$num = strrev[$num[0]] . "." . $num[1];
That covers the quick basics, but read on if you need more concrete examples.
