Question

我需要一个能清理字符串特殊字符的函数。我 NOT 希望这个转换HTML字符 <br /> 至 <br />

我希望将以下内容转换为：•，½，'到html代码。

这是我目前使用的功能，但它似乎不适用于分数..

function cleanText($str){

$str = str_replace("Ñ" ,"&#209;", $str);
$str = str_replace("ñ" ,"&#241;", $str);
$str = str_replace("ñ" ,"&#241;", $str);
$str = str_replace("Á","&#193;", $str);
$str = str_replace("á","&#225;", $str);
$str = str_replace("É","&#201;", $str);
$str = str_replace("é","&#233;", $str);
$str = str_replace("ú","&#250;", $str);
$str = str_replace("ù","&#249;", $str);
$str = str_replace("Í","&#205;", $str);
$str = str_replace("í","&#237;", $str);
$str = str_replace("Ó","&#211;", $str);
$str = str_replace("ó","&#243;", $str);
$str = str_replace("“","&#8220;", $str);
$str = str_replace("”","&#8221;", $str);

$str = str_replace("‘","&#8216;", $str);
$str = str_replace("’","&#8217;", $str);
$str = str_replace("—","&#8212;", $str);

$str = str_replace("–","&#8211;", $str);
$str = str_replace("™","&trade;", $str);
$str = str_replace("ü","&#252;", $str);
$str = str_replace("Ü","&#220;", $str);
$str = str_replace("Ê","&#202;", $str);
$str = str_replace("ê","&#238;", $str);
$str = str_replace("Ç","&#199;", $str);
$str = str_replace("ç","&#231;", $str);
$str = str_replace("È","&#200;", $str);
$str = str_replace("è","&#232;", $str);
$str = str_replace("•","&#149;" , $str);

$str = str_replace("¼","&#188;" , $str);
$str = str_replace("½","&#189;" , $str);
$str = str_replace("¾","&#190;" , $str);
$str = str_replace("½","&#189;" , $str);

return $str;

}

Answer 1

您可以使用ENT_SUBSTITUTE属性将htmlentities替换为整个功能。除了正常工作外，它还会更快地执行。

注意： ENT_SUBSTITUTE自PHP 5.4起可用。

Answer 2

猜猜是时候看一下htmlentities PHP函数及其选项了。

基本上，您可以用以下内容替换整个功能：

$str = htmlentities( $str );

它也会更有效率。

如果需要特殊处理（尤其是ENT_SUBSTITUTE），请务必查看函数的可选参数。

$str = htmlentities( $str, ENT_SUBSTITUTE );

试试这个，我用这个函数将任何东西/所有东西都转换为unicode：

class unicode_replace_entities {
public function UTF8entities($content="") {
    $contents = $this->unicode_string_to_array($content);
    $swap = "";
    $iCount = count($contents);
    for ($o=0;$o<$iCount;$o++) {
        $contents[$o] = $this->unicode_entity_replace($contents[$o]);
        $swap .= $contents[$o];
    }
    return mb_convert_encoding($swap, "UTF-8"); //not really necessary, but why not.
}
public function unicode_string_to_array( $string ) { //adjwilli
    $strlen = mb_strlen($string);
    while ($strlen) {
        $array[] = mb_substr( $string, 0, 1, "UTF-8" );
        $string = mb_substr( $string, 1, $strlen, "UTF-8" );
        $strlen = mb_strlen( $string );
    }
    return $array;
}
public function unicode_entity_replace($c) { //m. perez
    $h = ord($c{0});
    if ($h <= 0x7F) {
        return $c;
    } else if ($h < 0xC2) {
            return $c;
        }

    if ($h <= 0xDF) {
        $h = ($h & 0x1F) << 6 | (ord($c{1}) & 0x3F);
        $h = "&#" . $h . ";";
        return $h;
    } else if ($h <= 0xEF) {
            $h = ($h & 0x0F) << 12 | (ord($c{1}) & 0x3F) << 6 | (ord($c{2}) & 0x3F);
            $h = "&#" . $h . ";";
            return $h;
        } else if ($h <= 0xF4) {
            $h = ($h & 0x0F) << 18 | (ord($c{1}) & 0x3F) << 12 | (ord($c{2}) & 0x3F) << 6 | (ord($c{3}) & 0x3F);
            $h = "&#" . $h . ";";
            return $h;
        }
}
}

$oUnicodeReplace = new unicode_replace_entities();

$oUnicodeReplace->UTF8entities($string);

请注意，它将转换所有内容，但它会照顾奇怪的字符，否则......不是我自己的脚本，但我不知道我在哪里找到它。
