PHP - 将HTML符号转换为HTML实体

Question

$html_str = "Random Text™ First Second Third";

echo $str = html_entity_decode($html_str);

输出：Random Text™First Second Third

现在如何将$ str转换为$ html_str？

Answer 1

根据文件： “html_entity_decode（）与htmlentities（）相反......” http://php.net/manual/en/function.html-entity-decode.php

“htmlentities - 将所有适用的字符转换为HTML实体” http://php.net/manual/en/function.htmlentities.php

您想使用htmlentities

$html_str = htmlentities($str);
