temelde, ben istiyorum

  1. Her boş dizi eleman çıkarmak
  2. remove every array item without extensions ".jpg,.png,.gif" in its name;
  3. nihayet bu "digg,fb,tweet,bizspark" gibi anahtar kelimeleri içeren bir dizi öğeleri kaldırmak.

have tried ur code and it returns eg hi, ive tried the above code... it returns an array containing the stuff i want out.

herhangi bir fikir?

Merhaba gzip i kodu değiştirilmiş ve im daha iyi sonuçlar elde

function url_array_filter($url)
{
    static $words = array('digg', 'fb', 'tweet', 'bizspark','feedburner','feedads','CountImage');
    static $extens = array('.jpg', '.png', '.gif');
    $ret = true;
    if (!$url) {
        $ret = false;
    } elseif (str_replace($words, '', $url) != $url) {
        $ret = false;
    } else {
        $path = parse_url($url, PHP_URL_PATH);
        if (in_array(substr($path, -4), $extens)) {
            $ret = false;
        }
    }
    return $ret;
}

benim sorunum şimdi çıkışı ile birlikte gelir. örneğin

Array ( [0] => http://cdn.dzone.com/images/thumbs/120x90/491551.jpg' style='width:120;height:90;float:left;vertical-align:top;border:1px solid ) 

Array ( [0] => http://cdn.dzone.com/images/thumbs/120x90/490913.jpg' style='width:120;height:90;float:left;vertical-align:top;border:1px solid )

ben sadece url istiyorum. i orijinal içeriğinden adresler ayıklanması ile sorunumuz var. lemme bir origial soruya linki ve im ne yapıyor gönderebilirsiniz.

RSS Feeds and image extraction indepth

ben sadece url istiyorum. ben bu linki .... getImagesUrl () belki kadar karıştırmasını düşünüyorum. Doğru url geri getirmek için parse_url denemek ve kullanmak için gidiyoruz im. doğru yolda im olmadığını lemme biliyorum. im çok yakın rss görüntü adresler çekerek yönetmek için saksağan ile çözümlü beslemeleri

Ok GZip, this is the modification and addition ive added to ur code... 95% works!! great. although i do receive some funny results im posting below

function url_array_filter($url)
{
    static $words = array('digg', 'fb', 'tweet', 'bizspark','feedburner','feedads','CountImage','fuelbrand');
    static $extens = array('.jpg', '.png', '.gif');
    $ret = true;
    if (!$url) {
        $ret = false;
    } elseif (str_replace($words, '', $url) != $url) {
        $ret = false;
    } else {
        $path = parse_url($url, PHP_URL_PATH);
        if (in_array(substr($path, -4), $extens)) {
            $ret = false;
        }
    }
    return $ret;
} 

function cleanURL($a_url)
    {
    $ret=array();
    foreach ($a_url as $c)
        {
        $a=parse_url($c, PHP_URL_SCHEME).'://'.parse_url($c, PHP_URL_HOST).parse_url($c, PHP_URL_PATH);    
        $a=explode("'",$a);
        $ret[]=$a[0];
        }
    return $ret;         
    }

örnek kullanımı. $ This-> getImagesUrl ($ c); Aşağıdaki ilk soruda sonuçları döndürür.

                    foreach($content as $c) {
                        // get the images in content
                        $arr = $this->getImagesUrl($c);
                        $arr = array_filter($arr, 'url_array_filter');
                        }
                    $ret=cleanURL($arr);
                    if (count($ret)>0)
                        {
                        print_r($ret);                                
                        echo "<br/><br/>";
                        }

Bu noktaya kadar hemen hemen her şey harika çalışıyor ama ben gibi bazı kötü sonuçlar almaya devam
