解读PHP函数explode()的具体使用方法

目前PHP函数explode()把字符串分割为数组
explode(separator,string,limit)
separator 必需。规定在哪里分割字符串。
string 必需。要分割的字符串。
limit 可选。规定所返回的数组元素的最大数目。

PHP函数explode()例子
 

<ol class="dp-xml">
<li class="alt"><span><span class="tag"></span><span class="tag-name">php</span><span> </span></span></li>
<li>
<span>$</span><span class="attribute">str</span><span> = </span><span class="attribute-value">"Hello world. It's a beautiful day."</span><span>;  </span>
</li>
<li class="alt"><span>print_r (explode(" ",$str));  </span></li>
<li>
<span class="tag">?></span><span> </span>
</li>
</ol>

输出：
 

<ol class="dp-xml">
<li class="alt"><span><span>Array  </span></span></li>
<li><span>(  </span></li>
<li class="alt">
<span>[0] =</span><span class="tag">></span><span> Hello  </span>
</li>
<li>
<span>[1] =</span><span class="tag">></span><span> world.  </span>
</li>
<li class="alt">
<span>[2] =</span><span class="tag">></span><span> It's  </span>
</li>
<li>
<span>[3] =</span><span class="tag">></span><span> a  </span>
</li>
<li class="alt">
<span>[4] =</span><span class="tag">></span><span> beautiful  </span>
</li>
<li>
<span>[5] =</span><span class="tag">></span><span> day.  </span>
</li>
<li class="alt"><span>) </span></li>
</ol>
