strtok

實例

逐一分割字符串：

在下例中，請注意，我們僅在第一次調用strtok()函數時使用了string參數。在首次調用後，該函數僅需要split參數，這是因為它清楚自己在當前字符串中所在的位置。如需分割一個新的字符串，請再次調用帶string參數的strtok() ：

 <span class="token php language-php"><span class="token delimiter important"><?php</span>
<span class="token variable">$string</span> <span class="token operator">=</span> <span class="token string double-quoted-string">"Hello world. Beautiful day today."</span> <span class="token punctuation">;</span>
<span class="token variable">$token</span> <span class="token operator">=</span> <span class="token function">strtok</span> <span class="token punctuation">(</span> <span class="token variable">$string</span> <span class="token punctuation">,</span> <span class="token string double-quoted-string">" "</span> <span class="token punctuation">)</span> <span class="token punctuation">;</span>

<span class="token keyword">while</span> <span class="token punctuation">(</span> <span class="token variable">$token</span> <span class="token operator">!==</span> <span class="token constant boolean">false</span> <span class="token punctuation">)</span>
<span class="token punctuation">{</span>
<span class="token keyword">echo</span> <span class="token string double-quoted-string">" <span class="token interpolation"><span class="token variable">$token</span></span> <br>"</span> <span class="token punctuation">;</span>
<span class="token variable">$token</span> <span class="token operator">=</span> <span class="token function">strtok</span> <span class="token punctuation">(</span> <span class="token string double-quoted-string">" "</span> <span class="token punctuation">)</span> <span class="token punctuation">;</span>
<span class="token punctuation">}</span>
<span class="token delimiter important">?></span></span>
