<?php
$array = array("apple", "banana");
array_push($array, "orange", "grape");
print_r($array);
?>

Array
(
    [0] => apple
    [1] => banana
    [2] => orange
    [3] => grape
)

<?php
$array = array("apple", "banana");
$array[] = "orange";
$array[] = "grape";
print_r($array);
?>

Array
(
    [0] => apple
    [1] => banana
    [2] => orange
    [3] => grape
)

<?php
$array = array("apple", "banana");
$array[] = 123; // 这里会报错，因为数组中其他元素是字符串
?>

<?php
$array = array("apple", "banana");
$array[] = "123"; // 将数字转换为字符串
print_r($array);
?>

Array
(
    [0] => apple
    [1] => banana
    [2] => 123
)

<?php
ini_set('memory_limit', '256M'); // 增加内存限制
$array = array();
for ($i = 0; $i < 1000000; $i++) {
    $array[] = "item" . $i;
}
?>
