Question

“ł”不能实体化的原因是什么？

和对于一般不属于get_html_translation_table的字符，如何做到这一点？

如何指定/定义get_html_translation_table的内容？

（这里只讨论utf-8）

// control with 'ö'
php > echo htmlentities("ö",ENT_COMPAT,'utf-8');
&ouml;

// test with 'ł'
php > echo htmlentities("ł",ENT_COMPAT,'utf-8');
ł

检查get_html_translation_table：

php > var_dump(implode(',',array_keys(
                 get_html_translation_table(HTML_ENTITIES))));

// produces
// (why is ł not there?):

PHP 5.6.12

Answer 1

您需要使用ENT_HTML5标记处理代码为HTML 5。

echo htmlentities("ł", ENT_COMPAT | ENT_HTML5, 'utf-8');

Answer 2

php 5.3 ...您可以在以下针对UTF-8更改此功能（ISO-8859-2，WIN-1250）

<?php
if (!function_exists('htmlentities_polish')) { function htmlentities_polish($string) {

    if (!$GLOBALS['msFunc']['htmlentities_polish']['entities']) {
        $ignore = str_split('ACELNOSXZacelnosxz');  // Right Alt + that letter, on 'polish programmers keyboard' (or tilde (~) + that letter)
        // polish characters: Ą Ć Ę Ł Ń Ó Ś Ź Ż ą ć ę ł ń ó ś ź ż
        foreach ($ignore as &$value) {
            if (stripos('ae', $value)!==FALSE) $value .= 'ogon';
            else if (strtolower($value)==='l') $value .= 'strok';
            else if (strtolower($value)==='z') $value .= 'dot';
            else $value .= 'acute';
            $value = '&'.strtr($value, 'Xx' /* Z, z acute */, 'Zz').';';
            // See also: https://www.w3schools.com/charsets/ref_utf_latin_extended_a.asp , https://www.w3schools.com/charsets/ref_utf_latin1_supplement.asp
        }
        unset($value);
        $GLOBALS['msFunc']['htmlentities_polish']['entities'] = $ignore;

        $iso = array(161,198,202,163,209,211,166,172,175,177,230,234,179,241,243,182,188,191);  // ISO-8859-2

        }
    }

    return str_replace($GLOBALS['msFunc']['htmlentities_polish']['isowin'], $GLOBALS['msFunc']['htmlentities_polish']['entities'], $string);

    // otherwise // entities from WINDOWS-1250 and return :
    return str_replace($GLOBALS['msFunc']['htmlentities_polish']['win'], $GLOBALS['msFunc']['htmlentities_polish']['entities'], $string);

    // (2) slow but exact way 
    foreach (str_split($string) as $value) {
        if (in_array($value, $diff)) $iso_c++;
    }
    $diff = array_diff($GLOBALS['msFunc']['htmlentities_polish']['win'], $GLOBALS['msFunc']['htmlentities_polish']['iso']);
    foreach (str_split($string) as $value) {
        if (in_array($value, $diff)) $win_c++;

    else return str_replace($GLOBALS['msFunc']['htmlentities_polish']['iso'], $GLOBALS['msFunc']['htmlentities_polish']['entities'], $string);
    */
// polish characters: Ą Ć Ę Ł Ń Ó Ś Ź Ż ą ć ę ł ń ó ś ź ż
