例子1

按照指定長度對字符串進行折行處理：

 <span class="token php language-php"><span class="token delimiter important"><?php</span>
<span class="token variable">$str</span> <span class="token operator">=</span> <span class="token string double-quoted-string">"長單詞的一個例子：Supercalifragulistic"</span> <span class="token punctuation">;</span>
<span class="token keyword">echo</span> <span class="token function">wordwrap</span> <span class="token punctuation">(</span> <span class="token variable">$str</span> <span class="token punctuation">,</span> <span class="token number">15</span> <span class="token punctuation">,</span> <span class="token string double-quoted-string">"<br>\n"</span> <span class="token punctuation">)</span> <span class="token punctuation">;</span>

例子3

對字符串進行折行：

 <span class="token php language-php"><span class="token delimiter important"><?php</span>
<span class="token variable">$str</span> <span class="token operator">=</span> <span class="token string double-quoted-string">"An example of a long word is: Supercalifragulistic"</span> <span class="token punctuation">;</span>

以上代碼的HTML 輸出（請查看源代碼）：

 <span class="token operator"><</span> <span class="token operator">!</span> <span class="token constant">DOCTYPE</span> html <span class="token operator">></span>
<span class="token operator"><</span> html <span class="token operator">></span>
