How to write actual code for PHP string concatenation_PHP tutorial

To connect multiple strings, use a (.) "dot" sign, for example:

<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 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></SPAN><LI class=alt><SPAN>echo $name.".com";   </SPAN><LI class=""><SPAN></SPAN><SPAN class=tag><STRONG><FONT color=#006699>?></span></font></strong></span><span>   </span>
</li></ol>

The above output result is w3pop.com

There is a situation of PHP string connection. When echo is followed by (") double quotes, you can achieve the same effect as above:

<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 class=""><SPAN>$</SPAN><SPAN class=attribute><FONT color=#ff0000>name</FONT></SPAN><SPAN> = </SPAN><SPAN class=attribute-value><FONT color=#0000ff>"w3pop"</FONT></SPAN><SPAN>;//这句一样   </SPAN></SPAN><LI class=alt><SPAN>echo "$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 class=""><SPAN></SPAN><SPAN class=tag><STRONG><FONT color=#006699>?></span></font></strong></span><span>   </span>
</li></ol>

But if it is a single quote, the content inside will be output to the browser completely in string form:

<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 class=""><SPAN>$</SPAN><SPAN class=attribute><FONT color=#ff0000>name</FONT></SPAN><SPAN> = </SPAN><SPAN class=attribute-value><FONT color=#0000ff>"w3pop.com"</FONT></SPAN><SPAN>;   </SPAN></SPAN><LI class=alt><SPAN>echo '$name.com';   </SPAN><LI class=""><SPAN></SPAN><SPAN class=tag><STRONG><FONT color=#006699>?></span></font></strong></span><span>   </span>
</li></ol>

will display $name.com

PHP string concatenation example code:

<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 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></SPAN><LI class=alt><SPAN>echo $name.".com";   </SPAN><LI class=""><SPAN></SPAN><SPAN class=tag><STRONG><FONT color=#006699>?></span></font></strong></span><span>   </span>
</li>
<li class="alt">
<span></span><strong><font color="#006699"><span class="tag"><</SPAN><SPAN class=tag-name>br</SPAN></FONT></STRONG><SPAN> </SPAN><SPAN class=tag><STRONG><FONT color=#006699>/></span></font></strong><span>   </span>
</li>
<li class="">
<span></span><strong><font color="#006699"><span class="tag"><?</SPAN><SPAN class=tag-name>php</SPAN></FONT></STRONG><SPAN>   </SPAN></SPAN><LI class=alt><SPAN>$</SPAN><SPAN class=attribute><FONT color=#ff0000>name</FONT></SPAN><SPAN> = </SPAN><SPAN class=attribute-value><FONT color=#0000ff>"w3pop"</FONT></SPAN><SPAN>;   </SPAN></SPAN><LI class=""><SPAN>echo "$name.com";   </SPAN><LI class=alt><SPAN></SPAN><SPAN class=tag><STRONG><FONT color=#006699>?></span></font></strong><span>   </span>

</li>
</ol>
