问使用fputcsv将BOM添加到CSV文件

EN

function processForm($competition, $competitionEntry) {
    $BOM = "\xEF\xBB\xBF"; // UTF-8 BOM

    $filename = $competition->ID.".csv";
    $file = "entries/".$filename;     

    $fields = array_keys($competitionEntry);
    $submittedForm = $competitionEntry;

    if(file_exists($file)) {
        $fp = fopen($file, 'a');
        if($fp && 
            fputcsv($fp, $submittedForm) && 
            fclose($fp)) {
            return true;
        } 
    } else { // CREATE NEW FILE
        $fp = fopen($file, 'w');
        if($fp && 
            fputcsv($fp, $BOM) && // WRITE BOM TO FILE   
            fputcsv($fp, $fields) &&
            fputcsv($fp, $submittedForm) &&
            fclose($fp)) {     
            return true;
        } 
    }
    return false;
}
