【函数功能】

get_html_translation_table() 函数返回 htmlentities() 和 htmlspecialchars() 函数使用的翻译表。

【函数语法】

get_html_translation_table(function,flags,character-set)

【参数说明】

function：可选。规定返回哪个翻译表。
可能的值：
HTML_SPECIALCHARS - 默认。翻译需要 URL 编码的字符，以便正确显示在 HTML 页面上；
HTML_ENTITIES - 翻译所有需要 URL 编码的字符，以便正确地显示在 HTML 页面上；
flags：可选。规定翻译表将包含哪种引号以及翻译表用于哪种文档类型。
可用的引号类型：
ENT_COMPAT - 默认。翻译表包含双引号实体，不包含单引号实体。
ENT_QUOTES - 翻译表包含双引号实体和单引号实体。
ENT_NOQUOTES - 翻译表不包含双引号实体和单引号实体。
character-set：可选。字符串值，规定要使用的字符集。
允许的值：
UTF-8 - 默认。ASCII 兼容多字节的 8 位 Unicode
ISO-8859-1 - 西欧
ISO-8859-15 - 西欧（加入欧元符号 + ISO-8859-1 中丢失的法语和芬兰语字母）
cp866 - DOS 专用 Cyrillic 字符集
cp1251 - Windows 专用 Cyrillic 字符集
cp1252 - Windows 专用西欧字符集
KOI8-R - 俄语
BIG5 - 繁体中文，主要在台湾使用
GB2312 - 简体中文，国家标准字符集
BIG5-HKSCS - 带香港扩展的 Big5
Shift_JIS - 日语
EUC-JP - 日语
MacRoman - Mac 操作系统使用的字符集
注释：在 PHP 5.4 之前的版本，无法被识别的字符集将被忽略并由 ISO-8859-1 替代。自 PHP 5.4 起，无法被识别的字符集将被忽略并由 UTF-8 替代。

【演示程序】

<?php
/*
* get_html_translation_table()函数使用方法
* */
echo "HTML_SPECIALCHARS 的翻译表：(全部采用默认参数)<br>";
print_r(get_html_translation_table());//不传参数，全部采用默认值,即function参数为：HTML_SPECIALCHARS、flags参数为：ENT_COMPAT、character-set为：UTF-8
echo "<br>HTML_ENTITIES 的翻译表：<br>";
print_r(get_html_translation_table(HTML_ENTITIES));//function参数采用HTML_ENTITIES
echo "<br>HTML_SPECIALCHARS 的翻译表(包含单双引号)：<br>";
print_r(get_html_translation_table(HTML_SPECIALCHARS,ENT_QUOTES));//不传参数，全部采用默认值,即function参数为：HTML_SPECIALCHARS、flags参数为：ENT_COMPAT、character-set为：UTF-8
echo "<br>HTML_ENTITIES 的翻译表(包含单双引号)：<br>";
print_r(get_html_translation_table(HTML_ENTITIES,ENT_QUOTES));//function参数采用HTML_ENTITIES
?>

【特别注意】

1.某些字符可以按照多种方式进行编码。get_html_translation_table() 函数返回最普通的编码。
2.以数组形式返回翻译表，原始字符作为键名，实体作为键值(即键名是原始字符，值为html页面中需要写的字符串)。
3.PHP 版本：4+
