Question:
I've got a list of names separated by commas (they may contain other characters), or be empty, but generally looking like this:
NameA,NameB,NameC I need to create a function to delete a name if its present in the list and which restores the comma separated structure.
eg: if NameA is to be deleted, I should end up with:
NameB,NameC NOT
,NameB,NameC Similarly for the rest.
This is what I came up with, is there a better solution?
$pieces = explode(",", $list); $key=array_search($deleteuser, $pieces); if(FALSE !== $key) { unset($pieces[$key]); } $list = implode(",", $pieces);
Solution:1
You could use the array_splice function to delete from the array. With offset = array_search($deleteuser, $pieces) and length = 1.
Solution:2
That should work pretty well. You may also be interested in PHP's fgetcsv function.

Solution:3
You could also try a regular expression like this (maybe it can be optimized):
$search = 'NameB'; $list = 'NameA,NameB,NameC'; $list = preg_match('/(^' . $search . ',)|(,' . $search. ')/', '', $list); Note:If u also have question or solution just comment us below or mail us on toontricks1994@gmail.com
