<tr>
<td>

Answer 1

检查它们是否为empty -

$val = trim($row['addaddress']);
if(!empty($val)) {
     // display the table row or column
}

对于你的代码，它应该是 -

$val = trim($row['addaddress']);
if(!empty($val)) {
?>
    <td>
    <p class=MsoNormal style='margin-bottom:0in;margin-bottom:.0001pt;line-height:
    normal'><span style='font-size:12.0pt;mso-bidi-font-size:11.0pt;font-family:
    "Times New Roman","serif"'><b>Add. Address - </b> <?php echo $row['addaddress']; ?><o:p></o:p></span></p>
    <p> </p>
    </td>
<?php
}

Read this before using empty()

根据值使用检查。使用empty()时，如果值为0则为空。

Answer 2

您可以使用if条件检查值是否为空。它不会回应html，它是空的。

<?php if(!empty($row['addcity'])): ?>
<td>
<p class=MsoNormal style='margin-bottom:0in;margin-bottom:.0001pt;line-height:
normal'><span style='font-size:12.0pt;mso-bidi-font-size:11.0pt;font-family:
"Times New Roman","serif"'><b>Add. VPO/City - </b> <?php echo $row['addcity']; ?><o:p></o:p></span></p>
<p> </p>
</td>
<?php endif; ?>

Answer 3

需要解决非空状况：

<table>
<tr>
<td>
<p class=MsoNormal style='margin-bottom:0in;margin-bottom:.0001pt;line-height:
normal'><span style='font-size:12.0pt;mso-bidi-font-size:11.0pt;font-family:
"Times New Roman","serif"'><?php if(!empty($row['mobile'])){ echo "<b>Mobile No. ( ਮੋਬਿਲੇ ਨੋ.  ) - </b> ".$row['mobile']."" } ?><o:p></o:p></span></p>
<p> </p>
</td>

<td>
<p class=MsoNormal style='margin-bottom:0in;margin-bottom:.0001pt;line-height:
normal'><span style='font-size:12.0pt;mso-bidi-font-size:11.0pt;font-family:
"Times New Roman","serif"'><?php if(!empty($row['landline'])){ echo"<b>Landline - </b> ".$row['landline']."" } ?><o:p></o:p></span></p>
<p> </p>
</td>
</tr>

<tr>
<td>
<p class=MsoNormal style='margin-bottom:0in;margin-bottom:.0001pt;line-height:
normal'><span style='font-size:12.0pt;mso-bidi-font-size:11.0pt;font-family:
"Times New Roman","serif"'><?php if(!empty($row['addaddress'])){ echo"<b>Add. Address - </b> ".$row['addaddress']."" } ?><o:p></o:p></span></p>
<p> </p>
</td>
<td>
<p class=MsoNormal style='margin-bottom:0in;margin-bottom:.0001pt;line-height:
normal'><span style='font-size:12.0pt;mso-bidi-font-size:11.0pt;font-family:
"Times New Roman","serif"'><?php if(!empty($row['addcity'])){ echo "<b>Add. VPO/City - </b> ".$row['addcity']."" ?><o:p></o:p></span></p>
<p> </p>
</td>
