特殊文字を含むデータベースへのcsv

Question

私はワードプレスのcsvからデータベースへのデータの取り込みに取り組んでいます。下は私の関数です。問題は特殊文字（たとえばÂ）を正しく取り出すことができないことです。特別なcharectersでフェッチする。

public function process_feed(){ 

    // title, image URL, retail price, sale price, product link, SKU, group ID (new), inventory

すなわち、はutf8_encode /デコードを使用して機能format_product_nameを使用してみてください：

function format_product_name($title){ 
$title = str_replace("-", "", $title); 
$title = utf8_encode($title); 
//you can also try $title = utf8_decode($title); 
return $title; 
}; 

その後ポストコンテンツをフォーマットするためにそれを使用します。

... 
'post_title'  => $product_row['item_group_id'] . ' - ' . format_product_name($product_row['title']), 
'post_content' => format_product_name($product_row['description']), 
'post_excerpt' => format_product_name($product_row['description']), 
...

注：

それはUTFだことを確認するために設定し、データベースフィールドエンコーディングを確認し、ない場合は、あなたがそのため、それに合わせて、CSV形式のコンテンツをエンコードする必要があります、iconvまたは類似のPHPの関数を使用します。
