Edit report at https://bugs.php.net/bug.php?id=72995&edit=1 ID: 72995 Updated by: cmb@php.net Reported by: php at richardneill dot org Summary: wish: add 'else' to a 'foreach' block Status: Open Type: Feature/Change Request Package: Arrays related PHP Version: Irrelevant Block user comment: N Private report: N New Comment: You could also write: <?php if (empty($list)) { echo "Sorry, you have no fruit today.<br>"; } else foreach ($list as $fruit) { echo "You have a $fruit.<br>"; } Previous Comments: ------------------------------------------------------------------------ [2016-09-01 16:44:20] php at richardneill dot org Description: ------------ It would be useful if foreach supported an 'else' block, to be evaluated if there are no elements in the array. Just syntactic sugar, but it would make the program easier to read. This is similar in spirit to the enhancement request in: #60684 Test script: --------------- //One or other of these initial conditions: $list = array ("apple", "banana", "cherry"); $list = array(); //Print the list, handle the case where tje array is empty. foreach ($list as $fruit){ echo "You have a $fruit.<br>"; }else{ echo "Sorry, you have no fruit today.<br>"; } Expected result: ---------------- When the foreach array is empty, control passes into the else block. Otherwise, it doesn't. This makes the code easier to read, because we don't have to write things like: $atleastone=false; foreach ($list as $fruit){ echo "You have a $fruit.<br>"; $atleastone = true; } if (!$atleastone){ echo "Sorry, you have no fruit today.<br>"; } ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=72995&edit=1
