ListAppend

ListAppend is a rather simple utility function, however when you are dealing with lists, it can prove a great ally. This is a function that I pulled out of a class of list functions. I will publish the entire class once I get the individual functions published. The default delimiter for the ListAppend function is a ','. The delimiter length should be 1 character. Regardless of the size of the delimiter, the function will only use the first character.

The Function:

<php function ListAppend($list,$value,$delimiter= ",") { $delimiter = substr($delimiter,1); $nList = $list . $delimiter . $value; return $nList; } ?>

Usage:

Statement Output Comment ListAppend('elem1,elem2', '' ) elem1,elem2, Appended element is empty; delimiter is last character in list; list length is 2. ListAppend('', 'elem1,elem2' ) elem1,elem2 List length is 2. ListAppend("one___two", "three", "___") "one___two_three" Inserted the first character of delimiters before "three."

ListAppend works great to add values to a list. This function will default to a ',' for a delimiter! For Example: <?php $list = "abcd"; $value = "Z"; echo ListAppend($list,$value); ?> The results is 'abcd,Z'! By sending the correct delimiter through, in this case '': <?php $list = "abcd"; $value = "Z" ; echo ListAppend($list,$value,""); ?> The results is 'abcdZ'!
