Question

我正在尝试使用phpexcel让用户上传电子表格并插入到mysql中。我有它工作，除非用户在电子表格中有空行，它在数据库中放置了几个不必要的行。我已阅读并且mysql不支持检查约束，其中大部分需要在应用程序级别完成，这正是我想要做的。如何在PHP中检查特定列是否为空并跳过该行。任何帮助将不胜感激，或者如果有更好的解决方案我会为所有选项。我试了一段时间才得到它，bldg列是空的，而不是跳过那一行，但没有运气..

<?php require '../Classes/PHPExcel.php';
require_once '../Classes/PHPExcel/IOFactory.php';

$path = "../upload/uploads/$Filename";


$objPHPExcel = PHPExcel_IOFactory::load($path);
foreach ($objPHPExcel->getWorksheetIterator() as $worksheet) {
$worksheetTitle = $worksheet->getTitle();
$highestRow =  $worksheet->getHighestRow();
$highestColumn = 'L'; // e.g 'F'
$highestColumnIndex = PHPExcel_Cell::columnIndexFromString($highestColumn);
$nrColumns = ord($highestColumn) - 64;
$objReader = PHPExcel_IOFactory::createReaderForFile($path);
$objReader->setReadDataOnly(true);

echo '<br>Data: <table width="100%" cellpadding="3" cellspacing="0"><tr>';
for ($row = 16; $row <= $highestRow; ++ $row) {

echo '<tr>';
for ($col = 0; $col < $highestColumnIndex; ++ $col) {
$cell = $worksheet->getCellByColumnAndRow($col, $row);
$val = $cell->getValue();
if($row === 1)
echo '<td style="background:#000; color:#fff;">' . $val . '</td>';
else
echo '<td>' . $val . '</td>';
}
echo '</tr>';
}
echo '</table>';

for ($row = 16; $row <= $highestRow; ++ $row) {

$val=array();
    for ($col = 0; $col < $highestColumnIndex; ++ $col) {
    $cell = $worksheet->getCellByColumnAndRow($col, $row);
    $val[] = $cell->getValue();

    }


  $sql="insert into excess1(date_excessed, bldg, floor, jack, equipment_owner,     contact_name, contact_phone, qty, type_of_excess, asset_tag, service_tag, comments)
values('".$val[0] . "','" . $val[1] . "','" . $val[2]. "','" . $val[3]. "','" . $val[4].     "','" . $val[5]. "','".$val[6] . "','".$val[7] . "','".$val[8] . "','".$val[9] .     "','".$val[10] . "','".$val[11] . "')";

$result = mysql_query($sql) or die(mysql_error());

   print "$result";
