我正在尝试用php将html标记转换成字符串。但输出是不显示实际的html标签，输出显示hello world谢谢观看，我想输出为实际的html标签，请帮助我解决这个问题
<?php
$tag="<movie service='craftsman-1.0'><body><stack><sequence><effect type='sliding' duration='5.0'><image filename='http://s3.amazonaws.com/stupeflix-assets/apiusecase/Canyon_Chelly_Navajo.jpg'/><image filename='http://s3.amazonaws.com/stupeflix-assets/apiusecase/Ha_long_bay.jpg'/><image filename='http://s3.amazonaws.com/stupeflix-assets/apiusecase/Monument_Valley.jpg'/></effect><effect type='none'><video filename='http://s3.amazonaws.com/stupeflix-assets/apiusecase/footage.mov' audio='false'/></effect></sequence><text type='zone' align='center,center'>Hello World</text><audio filename='http://s3.amazonaws.com/stupeflix-assets/apiusecase/george_woods_lucky_one.mp3' skip='5.0'/></stack><text type='zone' align='center,center'> Thanks for watching!</text></body></movie>";
echo $tag;
?>
我想要这样的输出
<movie service='craftsman-1.0'><body><stack><sequence><effect type='sliding' duration='5.0'><image filename='http://s3.amazonaws.com/stupeflix-assets/apiusecase/Canyon_Chelly_Navajo.jpg'/><image filename='http://s3.amazonaws.com/stupeflix-assets/apiusecase/Ha_long_bay.jpg'/><image filename='http://s3.amazonaws.com/stupeflix-assets/apiusecase/Monument_Valley.jpg'/></effect><effect type='none'><video filename='http://s3.amazonaws.com/stupeflix-assets/apiusecase/footage.mov' audio='false'/></effect></sequence><text type='zone' align='center,center'>Hello World</text><audio filename='http://s3.amazonaws.com/stupeflix-assets/apiusecase/george_woods_lucky_one.mp3' skip='5.0'/></stack><text type='zone' align='center,center'> Thanks for watching!</text></body></movie>
但是输出显示如下
hello world thanks for watching
最佳答案
使用以下代码
<?php
$tag="<movie service='craftsman-1.0'><body><stack><sequence><effect type='sliding' duration='5.0'><image filename='http://s3.amazonaws.com/stupeflix-assets/apiusecase/Canyon_Chelly_Navajo.jpg'/><image filename='http://s3.amazonaws.com/stupeflix-assets/apiusecase/Ha_long_bay.jpg'/><image filename='http://s3.amazonaws.com/stupeflix-assets/apiusecase/Monument_Valley.jpg'/></effect><effect type='none'><video filename='http://s3.amazonaws.com/stupeflix-assets/apiusecase/footage.mov' audio='false'/></effect></sequence><text type='zone' align='center,center'>Hello World</text><audio filename='http://s3.amazonaws.com/stupeflix-assets/apiusecase/george_woods_lucky_one.mp3' skip='5.0'/></stack><text type='zone' align='center,center'> Thanks for watching!</text></body></movie>";
echo htmlentities($tag);
?>
