我试图找到一个函数删除表中的整个tr，并一起删除相应的$ variable = $ _POST ['variable']; 和$ variable =“'。$ variable。'”; 在我的页面脚本中。
<?php
require_once('common.php');
checkUser();
$page = 'traumato';
include('header.php');
?>
<?php
include('vervaldata.php');
if (isset($_POST['submit']))
{
// variabelen
// REK A1
$SPIRAALBLAD_HEUP = $_POST['SPIRAALBLAD_HEUP'];
$DENSIPROBE_PFNA = $_POST['DENSIPROBE_PFNA'];
$PFNA_BAK1 = $_POST['PFNA_BAK1'];
$DFN_INSTR = $_POST['DFN_INSTR'];
$DFN_IMPL = $_POST['DFN_IMPL'];
// herschrijven
$fh = fopen('./vervaldata.php', 'w');
fwrite($fh, '<?php
// REK A1
$SPIRAALBLAD_HEUP = "' . $SPIRAALBLAD_HEUP . '";
$DENSIPROBE_PFNA = "' . $DENSIPROBE_PFNA . '";
$PFNA_BAK1 = "' . $PFNA_BAK1 . '";
$DFN_INSTR = "' . $DFN_INSTR . '";
$DFN_IMPL = "' . $DFN_IMPL . '";
?>');
fclose($fh);
// opslagen
echo '<fieldset><p class="alert-box success"><span>Geslaagd: </span> Vervaldata werden aangepast!</p><meta HTTP-EQUIV="REFRESH" content="2; url=traumato.php"></fieldset>';}
?>
<fieldset><form action="./traumato.php" method="post">
<div class="alert-box2 box3"><b>VERVALDATA BERGING 2</b></div>

我可以从表中删除tr，但我也想从脚本中删除变量。如果可能的话，我现在不知道吗？
提前。
您可以执行以下操作：
if( !isset($remove_SPIRAALBLAD_HEUP)){ echo '<tr><td>A1</td><td>SPIRAALBLAD HEUP</td><td>'.$SPIRAALBLAD_HEUP.'</td><td><button></button></td></tr>'; }
现在，如果您输入$remove_SPIRAALBLAD_HEUPfalse，例如true，该行将不会显示在屏幕上。
另外，不要将PHP写到文件中！这会带来重大风险，并且实用性很差。只需将数据写入文件（或数据库）中，下次需要时，再次将其导入。您可能想要尝试serialize()或json_encode()获取数据。
