php Foreach：检查它是否是最后一项

Posted 2021-05-05

<?php

//NOT ALWAYS WORKING?
$last_item_index = sizeof($object) - 1;
foreach ($object as $item){
    if (next($object) === FALSE)
        $last_item = $item;
}


//OR
$numItems = count($arr);
$i = 0;
foreach($arr as $key=>$value) {
  if(++$i === $numItems) {
    echo "last index!";
  }
}
