How does PHP escape HTML?

PHP 如何转义 HTML？

在PHP中可以使用“htmlentities()”函数将HTML进行转义，该函数用于将字符转换为HTML转义字符，其语法是“htmlentities($str)”，其参数$str表示要转义的HTML字符串，返回值为编码后的字符。

示例

<?php
$str = "A &#39;quote&#39; is <b>bold</b>";

// 输出: A &#39;quote&#39; is &lt;b&gt;bold&lt;/b&gt;
echo htmlentities($str);

// 输出: A &#039;quote&#039; is &lt;b&gt;bold&lt;/b&gt;
echo htmlentities($str, ENT_QUOTES);
?>
Copy after login
