Question

标题说明了一切，它检测HTML中的引号。我怎么能不这样做呢？

$html = fopen($videoname."/video.html", "w") or die("Unable to Play Video");
$txt = "<html><body><video width="1000" controls>
    <source src="video.mp4" type="video/mp4">
    Your browser does not support HTML5 video.
</video></body></html>";
fwrite($html, $txt);
fclose($html);

Answer 1

胜利者说，

，或者：

$txt = '<html><body><video width="1000" controls>
    <source src="video.mp4" type="video/mp4">
    Your browser does not support HTML5 video.
</video></body></html>';

或

$txt = <<<EOT
<html><body><video width="1000" controls>
    <source src="video.mp4" type="video/mp4">
    Your browser does not support HTML5 video.
</video></body></html>
EOT;

Answer 2

你需要＆＃34;逃避＆＃34;你的引号。请尝试以下方法：

$txt = "<html><body><video width="1000" controls>
    <source src=\"video.mp4\" type=\"video/mp4\">
    Your browser does not support HTML5 video.
</video></body></html>";

Answer 3

这称为字符串转义

$html = fopen($videoname."/video.html", "w") or die("Unable to Play Video");
$txt = "<html><body><video width='1000' controls>
    <source src='video.mp4' type='video/mp4'>
    Your browser does not support HTML5 video.
</video></body></html>";
fwrite($html, $txt);
fclose($html);

如果您使用双引号打开块，则必须使用单引号''转义其中的任何属性，反之亦然。

将html放入php中的字符串时，如何检测引号？
