Example 1:
<?php header('content-type:text/html;charset=utf-8'); $num = array(10, 45, 9); echo "原数组："; var_dump($num); array_push($num, 100, 6); //在数组结尾插入元素 echo "插入多个元素后："; var_dump($num); ?>
Note: Even if your array has string keys, the elements you add will have numeric keys.
Example 2:
<?php
header('content-type:text/html;charset=utf-8');
$arr= array("a"=>"red","b"=>"green");
echo "原数组：";
var_dump($arr);
array_push($arr, "blue","yellow"); //在数组结尾插入元素
echo "插入多个元素后：";
var_dump($arr);
?>
