php 数组最后一个

$array = array(1, 2, 3, 4, 5);
$lastElement = end($array);
echo $lastElement; // 输出 5

$array = array(1, 2, 3, 4, 5);
$lastElement = array_pop($array);
echo $lastElement; // 输出 5

$array = array(1, 2, 3, 4, 5);
$lastElement = $array[count($array) - 1];
echo $lastElement; // 输出 5

$array = array();
$lastElement = end($array); // 这将导致警告：end() expects parameter 1 to be array, boolean given

$array = array();
if (!empty($array)) {
    $lastElement = end($array);
    echo $lastElement;
} else {
    echo "数组为空";
}
