Question

I have two columns in my SQL table where the phone numbers are stored.
I have displayed both the numbers separated by a ",".
If I concatenate both the data with "," for displaying, the problem I am facing is – when the first column is blank I am getting the output as ",xxxxxxxxxx" and when the second column is blank I am getting the output as "xxxxxxxxx,".
I am getting the perfect output only when both the columns contain data like "xxxxxxxxx,xxxxxxxxx".

How can I remove the extra "," when the data for either of the columns are missing?

Answer 1

This will do the trick.

$ret = implode(',', array_filter(array($value1, $value2)));
