How to make a comma seperated list that looks nice
06Oct06 Brian
Several times throughout the code, I want to print out a list of items, seperated correctly by a comma. Example:
Users browsing this thread: briantech, spinlock, bobjones, jamesgreer, nancyreagan
It would be painfully easy to just iterate through your array, printing out the array value followed by a comma. The problem with that though, is at the end of your list, your last element is going to have a comma at the end, which looks silly. So, instead you can just do this:
for ($i=0;$i < length($array);$i++)
{
print $array[$i];
if ($i+1 != length($array) )
print ",";
}
This way it puts a comma after your value for every value except the last one.
Alternatively, in Ruby:
array.join(”, “)
Boy talk about being right. You can do that in php too… implode($array, “,”);
I suck
