【PHP字符串】今天遇到一个很神奇的问题,请大家帮忙
错误一:

<br />echo 'echo $rst4[$i]["tb_restore_content"]:<br>';<br />echo $rst4[$i]['tb_restore_content']."<br><br>";<br />echo 'echo $rst4[$i]["tb_restore_content"]的内容:<br>';<br />echo '<font color="gray"><i><font color="red">【回复:sasasa】 </font><font color="gray"><i><font color="red">【回复:sasasa】 </font>0 </i></font><br/> 1 </i></font><br/> 2 ';<br />
Copy after login

运行结果

由于直接输出变量a时有些标签没有被解析,由于有给它加了双引号,又出现了以下错误
错误二
<br />echo is_string($rst4[$i]['tb_restore_content']);<br />echo "$rst4[$i]['tb_restore_content']";<br />
Copy after login

结果

------解决思路----------------------
为什么呢,看不出来,找出原因了吗?
------解决思路----------------------
是很神奇!
对于错误一,神奇在于你没把问题说清楚
对于错误二,神奇在于你没按 php 书写规则书写
echo "$rst4[$i]['tb_restore_content']";
应写作
echo "{$rst4[$i]['tb_restore_content']}";

echo $rst4[$i]['tb_restore_content'];

------解决思路----------------------
有什么不对吗?
