Question

我正在导入CSV，但是不幸的是，csv数字值已作为字符串导入，我尝试通过强制转换(int)和(float)并使用{{1}将字符串转换为整数和浮点值}和intval()，但结果为floatval()和0，在数据库中，值也分别存储为0和0，因为必须严格添加字段只接受整数和浮点值，不接受字符串。

那么我该如何解决？

我也使用了一个函数对其进行编码，但结果仍然相同：

0.00

我的数组如下：

/**
 * Convert csv source data into correct encoding data  
 * 
 */
protected function encodeField($field) {
    return iconv(mb_detect_encoding($field, mb_detect_order(), true), "iso-8859-1", $field);
}

我的CSV导入代码：

CSV文件结构如下：

/**
 * import mediahawk csv and store data 
 * 
 * @param sfWebRequest $request
 */
public function executeImportMediahawkCsv(sfWebRequest $request) {
    $this->form = new importMediahawkStatForm();
    $this->form->setDefault('month', date('m'));
    $this->form->setDefault('year', date('Y'));
    $this->exceptions = $this->notRelatedRecords = array();
    if ($request->isMethod('POST')) {
        $params = $request->getParameter($this->form->getName());
        $files = $request->getFiles($this->form->getName());
        $this->form->bind($params, $files);
        if ($this->form->isValid()) {
            $month = $params['month'];
            $year = $params['year'];
            $oldData = Doctrine::getTable('MediahawkStat')->findByMonthAndYear($month, $year);
            $file = $files['file']['tmp_name'];
            $handle = fopen($file, "r");
            $csvRecords = array();
            $venueNames = array(); // store venue names
            $i = 0;
            while ($data = fgetcsv($handle, 1000, ",", "'")) {
                if ($i > 0 && trim($data['0']) != 'Totals') {
                    $name = str_replace('"', '', $data['0']);
                    $venueNames[] = $this->encodeField($name);
                    $csvRecords[$i]['name'] = $name;
                    $csvRecords[$i]['month'] = $month;

                    $csvRecords[$i]['effective_per'] = $data['6'];
                    $csvRecords[$i]['ineffective_calls'] = $data['7'];
                    $csvRecords[$i]['ineffective_per'] = $data['8'];

                }
                $i++;
            }
            error_log(print_r($csvRecords, true));

在苦苦挣扎了一段时间之后，终于尝试了不同的事情，简单的str_replace()函数帮助并编写了以下简单函数来完成这项工作：

/**
 * Remove quotes from the numerical values
 */
protected function removeQuotes($field) {
    return str_replace('"', '', $field);
}

将上述功能应用于所有字段后，现在一切都可以正常运行：

更新的代码部分：

    $name = $this->removeQuotes($data['0']);
    $venueNames[] = $this->encodeField($name);
    $csvRecords[$i]['name'] = $name;
    $csvRecords[$i]['month'] = $month;
    $csvRecords[$i]['year'] = $year;
    $csvRecords[$i]['status'] = '';
    $csvRecords[$i]['total_calls'] = $this->removeQuotes($data['3']);
    $csvRecords[$i]['total_call_per'] = $this->removeQuotes($data['4']);
    $csvRecords[$i]['effective_calls'] = $this->removeQuotes($data['5']);
    $csvRecords[$i]['effective_per'] = $this->removeQuotes($data['6']);
    $csvRecords[$i]['ineffective_calls'] = $this->removeQuotes($data['7']);
    $csvRecords[$i]['ineffective_per'] = $this->removeQuotes($data['8']);
    $csvRecords[$i]['unique_calls'] = $this->removeQuotes($data['9']);
    $csvRecords[$i]['unique_per'] = $this->removeQuotes($data['10']);

现在正确的数组输出：

将CSV数字字符串转换为整数和浮点值？
