PHP函数将HTML代码转换为普通字符 [英] PHP function to convert from html codes to normal chars

问题描述

我有一个像这样的字符串：

I have a string like this:

La Torre Eiffel paragonata all&＃8217; Everest

我应该使用什么PHP函数转换&＃8217; 到实际的普通字符'：

What PHP function should I use to convert the ’ to the actual "normal" char ':

La Torre Eiffel paragonata all'Everest

La Torre Eiffel paragonata all’Everest

我正在使用CURL来获取页面，并且该页面中包含该字符串，但是由于某种原因

I'm using CURL to fetch a page and this page has that string in it but for some reason the HTML chars are not decoded.

my_url 测试页是一个带有iso字符的意大利语博客，所有

The my_url test page is an Italian blog with iso characters, and all the apostrophes are encoded in html code like above.

$output = curl_download($my_url);
$output = htmlspecialchars_decode($output);

function curl_download($Url){

    // is cURL installed yet?
    if (!function_exists('curl_init')){
        die('Sorry cURL is not installed!');
    }

    // OK cool - then let's create a new cURL resource handle
    $ch = curl_init();

    // Now set some options (most are optional)

    // Set URL to download
    curl_setopt($ch, CURLOPT_URL, $Url);

    // Set a referer
    curl_setopt($ch, CURLOPT_REFERER, "http://www.example.org/yay.htm");

    // User agent
    curl_setopt($ch, CURLOPT_USERAGENT, "MozillaXYZ/1.0");

    // Include header in result? (0 = yes, 1 = no)
    curl_setopt($ch, CURLOPT_HEADER, 0);

    // Should cURL return or print out the data? (true = return, false = print)
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

    // Timeout in seconds
    curl_setopt($ch, CURLOPT_TIMEOUT, 10);

    // Download the given URL, and return output
    $output = curl_exec($ch);

    // Close the cURL resource, and free system resources
    curl_close($ch);

    return $output;
}

推荐答案

html_entity_decode 。从php.net手册开始：html_entity_decode（）与htmlentities（）相反，它可以将字符串中的所有HTML实体转换为它们的适用字符。

html_entity_decode. From the php.net manual: html_entity_decode() is the opposite of htmlentities() in that it converts all HTML entities in the string to their applicable characters.
