卷曲file_get_contents / get_meta_tags编码

Question

so I'm using CURL to replace the file_get_contents and get_meta_tags functionality in PHP:

<?php

class CURL{


    public static function file_get_contents($url){

        $ch = curl_init();

        curl_setopt($ch, CURLOPT_HEADER, 0);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
        curl_setopt($ch, CURLOPT_URL, $url);
        curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);

        $data = curl_exec($ch);
        curl_close($ch);

        iconv("Windows-1252","UTF-8",$text);

        return $data;


    }


    public static function get_meta_tags($url){

        $html = self::file_get_contents($url);
        self::get_meta_tags_html($html);



    }

    public static function get_meta_tags_html($html){

        //parsing begins here:
        $doc = new DOMDocument();
        @$doc->loadHTML($html);
        //$nodes = $doc->getElementsByTagName('title');

        //get and display what you need:
        //$title = $nodes->item(0)->nodeValue;

        $metas = $doc->getElementsByTagName('meta');

        $return = array();

        for ($i = 0; $i < $metas->length; $i++)
        {
            $meta = $metas->item($i);
            if($meta->getAttribute('name') == 'title')
               $return["title"] = $meta->getAttribute('content');
            if($meta->getAttribute('name') == 'description')
                $return['description'] = $meta->getAttribute('content');
            if($meta->getAttribute('name') == 'keywords')
                $return['keywords'] = $meta->getAttribute('content');
        }

        return $return;

    }


}


?>

but then when I call CURL::get_meta_tags, on a site that has foreign letters in it such as Japanese, it will return weird characters instead of the Japanese letters whereas if I use the built in php get_meta_tags, it will return the correct character...

how should I modify this code such that CURL::get_meta_tags also return foreign characters properly just like the built in php get_meta_tags

Answer 1

It is more likely that you are just trying to display the text with the wrong encoding.

If you set the character set using the header function it should look correct.

header('Content-Type: text/html; charset=utf-8');

You could check what the character-set is in the meta tag you receive if it was set, and use that.
