用不同的字符分隔數組元素：

 <span class="token php language-php"><span class="token delimiter important"><?php</span>
<span class="token variable">$arr</span> <span class="token operator">=</span> <span class="token keyword">array</span> <span class="token punctuation">(</span> <span class="token string single-quoted-string">&#39;Hello&#39;</span> <span class="token punctuation">,</span> <span class="token string single-quoted-string">&#39;World!&#39;</span> <span class="token punctuation">,</span> <span class="token string single-quoted-string">&#39;I&#39;</span> <span class="token punctuation">,</span> <span class="token string single-quoted-string">&#39;love&#39;</span> <span class="token punctuation">,</span> <span class="token string single-quoted-string">&#39;Shanghai!&#39;</span> <span class="token punctuation">)</span> <span class="token punctuation">;</span>
