創建名為$cars 的索引數組，向它賦三個元素，然後打印包含數組值的文本：
<span class="token php language-php"><span class="token delimiter important"><?php</span> <span class="token variable">$cars</span> <span class="token operator">=</span><span class="token keyword"></span></span><mark> <span class="token keyword">array</span> <span class="token punctuation">(</span> <span class="token string double-quoted-string">"Volvo"</span> <span class="token punctuation">,</span> <span class="token string double-quoted-string">"BMW"</span> <span class="token punctuation">,</span> <span class="token string double-quoted-string">"Toyota"</span> <span class="token punctuation">)</span></mark><span class="token punctuation"></span> <span class="token punctuation">;</span> <span class="token keyword">echo</span> <span class="token string double-quoted-string">"I like "</span> <span class="token operator">.</span> <span class="token variable">$cars</span> <span class="token punctuation">[</span> <span class="token number">0</span> <span class="token punctuation">]</span> <span class="token operator">.</span> <span class="token string double-quoted-string">", "</span> <span class="token operator">.</span> <span class="token variable">$cars</span> <span class="token punctuation">[</span> <span class="token number">1</span> <span class="token punctuation">]</span> <span class="token operator">.</span> <span class="token string double-quoted-string">" and "</span> <span class="token operator">.</span> <span class="token variable">$cars</span> <span class="token punctuation">[</span> <span class="token number">2</span> <span class="token punctuation">]</span> <span class="token operator">.</span> <span class="token string double-quoted-string">"."</span> <span class="token punctuation">;</span> <span class="token delimiter important">?></span>
創建名為$age 的關聯數組：
