输出 htmlspecialchars 函数使用的翻译表:
<?php
print_r (get_html_translation_table()); // HTML_SPECIALCHARS is default.
?>
定义和用法
get_html_translation_table() 函数返回 htmlentities() 和 htmlspecialchars() 函数使用的翻译表。
提示:一些字符可以按照若干种方式进行编码。get_html_translation_table() 函数返回最普通的编码。
语法
get_html_translation_table(function,flags,character-set)
参数 | 描述 |

可用的引号类型:
规定翻译表适用的文档类型的附加 flags:
|
character-set | 可选。一个规定了要使用的字符集的字符串。
允许的值:

技术细节
返回值: | 以数组形式返回翻译表,原始字符作为键名,实体作为键值。 |
---|---|
PHP 版本: | 4+ |
更新日志: | 在 PHP 5 中,character-set 参数的默认值改为 UTF-8。 在 PHP 5.4 中,新增了用于规定翻译表适用的文档类型的附加 flags:ENT_HTML401、ENT_HTML5、ENT_XML1 和 ENT_XHTML。 在 PHP 5.3.4 中,新增了 character-set 参数。 |
