Question

我正在处理一些代码，我从stackoverflow和一些旧代码中拼凑了以下一些代码。无论如何，我试图让文件被解析和处理，而不是实际显示其内容，而是在后期进行。有PHP：

$c = 0;
             if($fp = fopen($newname,"r"))
             { 
                 while (($line = fgets($fp)) !== false)
                 {
                          //CHECK STRING TO SEE IF IT CONTAINS AN EMAIL                         
                         $checkResult = $this->checkCSVContentForEmail($line,$c);//$content
                          if(!empty($checkResult))
                          {
                            if($checkResult == TRUE && is_bool($checkResult) == true)
                            {

                                   $this->contactsAddedCounter += 1;
                            }

                            elseif(is_string($checkResult))
                            {
                                $errLine .= '
                                 <p> CheckResult: '.$checkResult.' &nbsp; Line number: '.$c.' does not have an email</p>';
                                 array_push($this->LogError_contactsUpload, $errLine);  
                            }
                          }
                          else
                          {
                              $errLine = "<p>Line number: ".$c." contain's an empty string</p><br>\n";
                              array_push($this->LogError_contactsUpload, $errLine);
                          }

                    $c++;
                }
             }
             fclose($fp);

我昨天花了整整一天编写所有涉及的代码 - 函数和所有但不应该做任何显示，但我仍然会显示以下内容，

不需要的输出：

Array ( [0] => " [1] => [2] => [3] => [4] => Normal"" [5] => ""False"" [6] => [7] => [8] => ""Normal""";;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; )

当然，对于每行读取都会重复显示。

对可能导致此问题的任何帮助？

处理中涉及的其余代码： //检查电子邮件方法行公共函数checkCSVContentForEmail（$ csvLine，$ lineNum） { 如果（！空（$ csvLine）） {
$ partedCSV = explode（'，'，$ csvLine）;

     if(!empty($partedCSV[57]))
     {
        $csvEmail = $partedCSV[57];
        if(!empty($csvEmail))
        {
             if($Result = $this->checkEmail($csvEmail, $lineNum))
             {
                //convert csv line into sql statement
                $csv2sqlInsertMultiLine = '(';
                $csvTosql = '';
                foreach($partedCSV as $csvContent)
                {
                    $str = strip_tags($csvContent);
                    $letters = array('"', "'");
                    $Quotes   = array('', ' ');

                    $letters = array('(', ")");
                    $Quotes   = array('', '');
                    $c2s_str  = str_replace($letters, $Quotes, $strN);
                    $csvTosql[] .= $c2s_str;

                }
                    //(4,5,6);
                    $theSQL = implode(',',$csvTosql);
                    $csv2sqlInsertMultiLine .= $theSQL;
                    $csv2sqlInsertMultiLine .= '),';
                    array_push($this->csv2sqlInsertMultiLine, $csv2sqlInsertMultiLine);

                return $Result; 
             }
        }
     }
     else
     {
        $show = 'No Entry for Email address field - WILL NOT BE ADDED TO DATABASE! '.print_r($partedCSV); 
        return $show;
     }
    }
    else
    {
        $show = 'This line is empty';
        return $show;
    }
}
//Validate Email Method
public function checkEmail($email, $row)
{
    if(!empty($email))
    {
        $str = strip_tags($email);
        $letters = array('"', "'");
        $Quotes   = array('', ' ');
        $em  = str_replace($letters, $Quotes, $str);

        if(!empty($em) or $em !=' ')
        {
            $check = preg_match('/^\S+@[\w\d.-]{2,}\.[\w]{2,6}$/iU', $em) ? TRUE : FALSE;

             if($check == TRUE)
             {

JQuery

// Upload Contacts
function uploadContacts()
{
    var obj = '#upImprtFile';

    var file_data = $k('#ContactsImprt').prop('files')[0];
    var form_data = new FormData();
    form_data.append("action", "uploadContacts");
    form_data.append("upImprtFile", "submit");
    form_data.append("ContactsImprt", file_data);

Answer 1

请参阅checkCSVContentForEmail方法内的以下几行。

else
     {
        $show = 'No Entry for Email address field - WILL NOT BE ADDED TO DATABASE! '.print_r($partedCSV); 
        return $show;
     }

使用print_r必须导致输出。
