Some docs for the reduce_multiples function:

Code:

<h2>reduce_multiples()</h2>
<p>Reduces multiple instances of a particular character occuring directly after each other. Example:</p>
<code>
$string="Fred, Bill,, Joe, Jimmy";
$string=reduce_multiples($string,","); //results in "Fred, Bill, Joe, Jimmy"
</code>
<p>The function accepts the following parameters:
<code>reduce_multiples(string: text to search in, string: character to reduce, boolean: whether to remove the character from the front and end of the string)</code>

The first parameter contrains the string in which you want to reduce the multiplies. The second parameter contains the character you want to have reduced.
The third parameter is False by default. If it it's to true it will remove occurences of the character at the beginning and the end of the string. Example:

<code>
$string=",Fred, Bill,, Joe, Jimmy,";
$string=reduce_multiples($string,",",true); //results in "Fred, Bill, Joe, Jimmy"
</code>
