help with first function

[niche]

I'd like to turn this into a function to reduce multiple spaces to one space between characters:

$var = trim($var);//echo $var;while (strpos($var,"  ") > 0) {  $var = str_replace("  "," ",$var);}  

How do I make this into a function?Thanks

something like this:

function strip_white_space($var) {$var = trim($var);while (strpos($var,"  ") > 0) {  $var = str_replace("  "," ",$var);return $var;} }

A regex might be more suitable if you wanted to reduce any number of whitespaces to one:$var = preg_replace('/\s+/'," ",$var);

Where do I place the function in the script (presumably it has to be inserted before I can use it)?

You can put it wherever you want it, as long as you declare it within the scope in which you need it. I typically keep my functions near the top of my scripts.

For example

function3 () {   //  blah}function2 () {   //  blah}function1 () {   //  blah}main() {   function1();   function2();   function3();}main();
