Question

我正在尝试将html标签转换为php中的字符串。但输出是不显示实际的html标签，输出显示你好世界感谢观看，我想输出为实际的html标签，请帮我解决这个问题

 <?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>

但输出显示如下

Answer 1

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);

＆GT;

Answer 2

使用strip_tags（）它实现我们所期望的实际输出，字符串 strip_tags ( string $str [, string $allowable_tags ] ) 此函数尝试返回一个字符串，其中包含从给定str中剥离的所有NULL字节，HTML和PHP标记。它使用与fgetss（）函数相同的标签剥离状态机。

参数

str： 输入字符串。

allowable_tags： 您可以使用可选的第二个参数来指定不应剥离的标记。

$tag=" <movie service='craftsman-1.0'><body><stack><sequence><effect type='sliding'  duration='5.0'><image filename='http://s3.amazonaws.com/stupeflix-assets/apiusecase/Canyon_Chelly_Navajo.jpg'/><image filename='http://s3.amazonaws.com/stupeflix-assets/apiusecase/Ha_long_bay.jpg'/><image filename='http://s3.amazonaws.com/stupeflix-assets/apiusecase/Monument_Valley.jpg'/></effect><effect type='none'><video filename='http://s3.amazonaws.com/stupeflix-assets/apiusecase/footage.mov' audio='false'/></effect></sequence><text type='zone' align='center,center'>Hello World</text><audio filename='http://s3.amazonaws.com/stupeflix-assets/apiusecase/george_woods_lucky_one.mp3' skip='5.0'/></stack><text type='zone' align='center,center'> Thanks for watching!</text></body></movie>";
    echo strip_tags($tag);
    echo "\n";
    echo strip_tags($tag, '<movie><body><stack><sequence><effect><image><video><text><audio>');

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>

Answer 3

 $tag="<movie service='craftsman-1.0'><body>..... </body></movie>"; //use quotes to enclose the string but make sure you don't have any double quotes in the string

这个长期heredoc的另一个字符串解决方案

$tag = <<<EOT
    <movie service='craftsman-1.0'><body>
    ......
    </body></movie>
EOT;

Answer 4

您的PHP变量需要用双引号括起来，如下所示：

$tag = "<movie service='etc...'>";

确保双引号内的所有HTML标记都使用单引号，否则它将结束PHP变量。（你的例子似乎很好）

最后也不要忘记你的分号！

至于使回显打印出实际的HTML标记，您需要使用PHP函数htmlentities。

echo htmlentities($tag);

Answer 5

这应该......

echo htmlspecialchars($tag);
