htmlentities 和 htmlspecialchars

用get_html_translation_table 调出两个函数的字符变换table

<?php
$table_e = get_html_translation_table(HTML_ENTITIES);
$table_s = get_html_translation_table(HTML_SPECIALCHARS);
echo "<br>----- htmlentities() の変換テーブル -----<br>";
print_r($table_e);
echo "<br>----- htmlspecialchars() の変換テーブル -----<br>";
print_r($table_s);
?>

结果如下：

----- htmlspecialchars() の変換テーブル -----
Array
(
    ["] => "
    [<] => <
    [>] => >
    [&] => &
)
----- htmlentities() の変換テーブル -----
