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 "$name.com"; </SPAN><LI class=alt><SPAN></SPAN><SPAN class=tag><STRONG><FONT color=#006699>?></span></font></strong><span> </span> </li> <li class=""> <span></span><strong><font color="#006699"><span class="tag"><</SPAN><SPAN class=tag-name>br</SPAN></FONT></STRONG><SPAN> </SPAN><SPAN class=tag><STRONG><FONT color=#006699>/></span></font></strong><span> </span> </li> <li class="alt"> <span></span><strong><font color="#006699"><span class="tag"><?</SPAN><SPAN class=tag-name>php</SPAN></FONT></STRONG><SPAN> </SPAN></SPAN><LI class=""><SPAN>$</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 '.com'; </SPAN><LI class=""><SPAN></SPAN><SPAN class=tag><STRONG><FONT color=#006699>?></span></font></strong><span> </span> </li> </ol>
Output result
