本文目录导读：
我来为你提供几个不同版本的PHP圣诞树代码,从简单到进阶：
基础控制台版本
<?php
// 基础圣诞树 - 控制台输出
function drawChristmasTree($height = 10) {
// 树冠部分
for ($i = 1; $i <= $height; $i++) {
echo str_repeat(' ', $height - $i);
echo str_repeat('*', 2 * $i - 1);
echo "\n";
}
// 树干部分
for ($i = 0; $i < 2; $i++) {
echo str_repeat(' ', $height - 2);
echo "***\n";
}
}
echo "🎄 圣诞快乐！🎄\n\n";
drawChristmasTree(10);
?>
彩色HTML版本
<?php
// 彩色HTML圣诞树
function drawHTMLTree($height = 12) {
$html = '<div style="text-align:center; font-family:monospace;">';
// 树顶星星
$html .= '<div style="color:gold; font-size:24px;">★</div>';
// 树冠
for ($i = 1; $i <= $height; $i++) {
$leaf = str_repeat('*', 2 * $i - 1);
$spaces = str_repeat(' ', $height - $i + 1);
// 随机装饰颜色
$colored_parts = '';
for ($j = 0; $j < strlen($leaf); $j++) {
$colors = ['green', '#228B22', '#006400', '#32CD32', '#90EE90'];
$decorations = ['red', 'gold', 'blue', 'purple', 'silver'];
// 随机添加装饰球
if (rand(1, 10) > 8) {
$color = $decorations[array_rand($decorations)];
$colored_parts .= "<span style='color:$color;'>●</span>";
} else {
$color = $colors[array_rand($colors)];
$colored_parts .= "<span style='color:$color;'>*</span>";
}
}
$html .= "<div style='font-size:20px;'>$spaces$colored_parts</div>";
}
// 树干
for ($i = 0; $i < 3; $i++) {
$trunk = str_repeat('|', 3);
$spaces = str_repeat(' ', $height - 1);
$html .= "<div style='color:brown; font-size:20px;'>$spaces$trunk</div>";
}
// 礼物
$html .= '<div style="color:red; font-size:30px; margin-top:10px;">🎁</div>';
$html .= '</div>';
return $html;
}
echo drawHTMLTree(8);
?>
动画效果版本
<?php
// 闪烁动画圣诞树
function drawAnimTree($height = 10) {
?>
<style>
@keyframes twinkle {
0% { opacity: 1; }
50% { opacity: 0.3; }
100% { opacity: 1; }
}
.tree-line {
font-family: 'Courier New', monospace;
font-size: 18px;
line-height: 1.4;
}
.star {
color: gold;
animation: twinkle 1s infinite;
font-size: 30px;
}
.light-red { color: #ff0000; animation: twinkle 0.7s infinite; }
.light-gold { color: #ffd700; animation: twinkle 1.2s infinite; }
.light-blue { color: #0000ff; animation: twinkle 0.9s infinite; }
</style>
<div style="text-align:center; background: #0a0a2e; padding: 20px; border-radius: 10px;">
<div class="star">✦ ✦ ✦</div>
<?php
for ($i = 1; $i <= $height; $i++) {
$spaces = str_repeat(' ', $height - $i + 3);
echo "<div class='tree-line'>$spaces";
for ($j = 0; $j < 2 * $i - 1; $j++) {
if (rand(1, 10) > 7) {
$lights = ['light-red', 'light-gold', 'light-blue'];
$class = $lights[array_rand($lights)];
echo "<span class='$class'>●</span>";
} else {
echo "<span style='color: darkgreen;'>*</span>";
}
}
echo "</div>";
}
// 树干
for ($i = 0; $i < 2; $i++) {
echo "<div class='tree-line'>";
echo str_repeat(' ', $height + 2);
echo "<span style='color: #8B4513;'>|||</span>";
echo "</div>";
}
echo "</div>";
}
drawAnimTree(10);
?>
函数封装版本（功能完整）
<?php
class ChristmasTree {
private $height;
private $colors = [
'green' => ['#006400', '#228B22', '#32CD32'],
'decorations' => ['#FF0000', '#FFD700', '#0000FF', '#FF69B4', '#FFA500']
];
public function __construct($height = 10) {
$this->height = $height;
}
// 生成星形
private function drawStar() {
echo "<div style='text-align:center; color:gold; font-size:24px;'>";
echo "★";
echo "</div>";
}
// 生成树枝
private function drawBranch($row) {
$spaces = str_repeat(' ', $this->height - $row + 2);
echo "<div style='text-align:center; font-family:monospace; font-size:16px;'>";
echo $spaces;
for ($i = 0; $i < 2 * $row - 1; $i++) {
if (rand(1, 8) > 6) {
$color = $this->colors['decorations'][array_rand($this->colors['decorations'])];
echo "<span style='color:$color;'>●</span>";
} else {
$color = $this->colors['green'][array_rand($this->colors['green'])];
echo "<span style='color:$color;'>▲</span>";
}
}
echo "</div>";
}
// 生成树干
private function drawTrunk() {
for ($i = 0; $i < 3; $i++) {
echo "<div style='text-align:center;'>";
echo str_repeat(' ', $this->height);
echo "<span style='color:#8B4513; font-size:16px;'>|||</span>";
echo "</div>";
}
}
// 生成完整的树
public function render() {
$html = "<div style='background: linear-gradient(to bottom, #001133, #000022); padding: 20px; border-radius: 10px;'>";
echo $html;
$this->drawStar();
for ($i = 1; $i <= $this->height; $i++) {
$this->drawBranch($i);
}
$this->drawTrunk();
echo "</div>";
}
}
// 使用示例
$tree = new ChristmasTree(8);
$tree->render();
?>
简洁实用版本
<?php
function xmas_tree($rows = 8) {
echo "<pre style='text-align:center; color:green;'>";
// 树顶
echo "<span style='color:gold;'>★</span>\n";
// 树冠
for ($i = 0; $i < $rows; $i++) {
$spaces = str_repeat(' ', $rows - $i);
$stars = str_repeat('*', (2 * $i) + 1);
// 添加装饰灯（随机位置）
$chars = str_split($stars);
foreach ($chars as $key => $char) {
if ($key % 2 == 0 && rand(1, 5) == 3) {
$colors = ['red', 'gold', 'blue'];
echo "<span style='color: {$colors[array_rand($colors)]};'>o</span>";
} else {
echo $char;
}
}
echo "\n";
}
// 树干
for ($i = 0; $i < 2; $i++) {
echo str_repeat(' ', $rows - 1);
echo "***\n";
}
echo "</pre>";
echo "<p style='text-align:center; color:red; font-size:20px;'>Merry Christmas! 🎄</p>";
}
xmas_tree(10);
?>
使用建议：
- 终端环境：使用版本1或版本5
- 网页展示：使用版本2、3或4
- 需要动画效果：使用版本3
- 面向对象编程：使用版本4
这些代码都带有装饰效果，可以根据需要调整树的高度和装饰风格，祝编码愉快！🎄✨
