要让多个字符串进行衔接，要用到一个(.)“点”号,比如:
<ol class="dp-xml"> <li class="alt"><span><strong><font color="#006699"><span class="tag"></span><span class="tag-name">php</span></font></strong><span> </span></span></li> <li class=""> <span>$</span><span class="attribute"><font color="#ff0000">name</font></span><span> = </span><span class="attribute-value"><font color="#0000ff">"w3pop"</font></span><span>; </span> </li> <li class="alt"><span>echo $name.".com"; </span></li> <li class=""> <span></span><span class="tag"><strong><font color="#006699">?></font></strong></span><span> </span> </li> </ol>
上面的输出结果就是w3pop.com
有一种PHP字符串连接的情况，当echo后面使用的是(")双引号的话可以这样来达到和上同样的效果：
<ol class="dp-xml"> <li class="alt"><span><strong><font color="#006699"><span class="tag"></span><span class="tag-name">php</span></font></strong><span> </span></span></li> <li class=""> <span>$</span><span class="attribute"><font color="#ff0000">name</font></span><span> = </span><span class="attribute-value"><font color="#0000ff">"w3pop"</font></span><span>;//这句一样 </span> </li> <li class="alt"><span>echo "$name.com";//双引号里的变量还是可以正常显示出来，<br>并和一般的字符串自动区分开来 </span></li> <li class=""> <span></span><span class="tag"><strong><font color="#006699">?></font></strong></span><span> </span> </li> </ol>
但如果是单引号的话，就会将里面的内容完全以字符串形式输出给浏览器：
<ol class="dp-xml"> <li class="alt"><span><strong><font color="#006699"><span class="tag"></span><span class="tag-name">php</span></font></strong><span> </span></span></li> <li class=""> <span>$</span><span class="attribute"><font color="#ff0000">name</font></span><span> = </span><span class="attribute-value"><font color="#0000ff">"w3pop.com"</font></span><span>; </span> </li> <li class="alt"><span>echo '$name.com'; </span></li> <li class=""> <span></span><span class="tag"><strong><font color="#006699">?></font></strong></span><span> </span> </li> </ol>
将显示$name.com
PHP字符串连接示例代码：
<ol class="dp-xml"> <li class="alt"><span><strong><font color="#006699"><span class="tag"></span><span class="tag-name">php</span></font></strong><span> </span></span></li> <li class=""> <span>$</span><span class="attribute"><font color="#ff0000">name</font></span><span> = </span><span class="attribute-value"><font color="#0000ff">"w3pop"</font></span><span>; </span> </li> <li class="alt"><span>echo $name.".com"; </span></li> <li class=""> <span></span><span class="tag"><strong><font color="#006699">?></font></strong></span><span> </span> </li> <li class="alt"> <span></span><strong><font color="#006699"><span class="tag"><span class="tag-name">br</span></span></font></strong><span> </span><span class="tag"><strong><font color="#006699">/></font></strong></span><span> </span> </li> <li class=""> <span></span><strong><font color="#006699"><span class="tag"></span><span class="tag-name">php</span></font></strong><span> </span> </li> <li class="alt"> <span>$</span><span class="attribute"><font color="#ff0000">name</font></span><span> = </span><span class="attribute-value"><font color="#0000ff">"w3pop"</font></span><span>; </span> </li> <li class=""><span>echo "$name.com"; </span></li> <li class="alt"> <span></span><span class="tag"><strong><font color="#006699">?></font></strong></span><span> </span> </li> <li class=""> <span></span><strong><font color="#006699"><span class="tag"><span class="tag-name">br</span></span></font></strong><span> </span><span class="tag"><strong><font color="#006699">/></font></strong></span><span> </span> </li> <li class="alt"> <span></span><strong><font color="#006699"><span class="tag"></span><span class="tag-name">php</span></font></strong><span> </span> </li> <li class=""> <span>$</span><span class="attribute"><font color="#ff0000">name</font></span><span> = </span><span class="attribute-value"><font color="#0000ff">"w3pop.com"</font></span><span>; </span> </li> <li class="alt"><span>echo '.com'; </span></li> <li class=""> <span></span><span class="tag"><strong><font color="#006699">?></font></strong></span><span> </span> </li> </ol>
输出结果
w3pop.com
w3pop.com.com
$name.com
怎么样，大家通过上面这三段代码的演示，是否已经初步掌握了PHP字符串连接的方法了呢？
