9,894 Pointsstrpos/ strstr confusion
Hi
I am confused as to why the browser doesn't display:
Egg Eggs Eggs
and instead only displays:
Egg Eggs
after the:
if (strpos($item, ",")) { $item = strstr($item, ",", true); }
statement is implemented. surely there should still be two'Eggs' in the display because there was both an Eggs and 'Eggs, Beaten' in the original shopping list and $item = strstr($item, "," , true) should still return 'Eggs' ( with the ", Beaten" removed). So why is there only one 'Eggs'? What happened to the other one?
Hope someone can help.

9,894 PointsHi Emma thanks for the answer, but I'm still confused. Although strpos does return only 'Eggs' there was already another item called Eggs (and a third item called Egg). I understand why Egg has disappeared but not Eggs. If there are any ideas I would be very grateful!!.
Thanks again

if (strpos($item, ",")) { $item = strstr($item, ",", true); }So there will only be one Eggs
