Jason Wong,您好！
Thank you,Mr. Jason Wong,I think what you said is below.If not,tell me
the right way,ok?
=============================filename:edit.php=======(still have
ERRORs)=================begin==>
<? if (isset($_GET['action']) && $_GET['action'] == 'del' && !empty($_GET['id']))
{
$news=file("this.txt");
$fp1 = fopen('outputfile', 'w');
foreach ($news as $line) {
if (strpos($line, $_GET['id']) !== 0)
{
fwrite($fp, $line);
}
}
fclose($fp1);
}
$news=file('this.txt');
$num=count($news);
$fp=fopen('outputfile','w');
echo "<TABLE>";
for($i=0;$i<$num;$i++)
{
echo "<tr><td>".$news[$i]."</td><td> <a href='edit.php?action=del&id=$i'>DELETE THIS
LINE</a></td></tr>";
if(($action==del)&&($id!==$i)){
@fwrite($fp,$news[$i]);
}
}
echo "</table>ok";
fclose($fp);?>
<====================================end
Is there any wrong above?Sorry,it do nothing again.
A friend told me to use "UNSET" and I'v got it,here's the source code of another way.
I'v got it from below source code,I'd like to share the code with you.
Although I'v got it,to study more knowledge--on the other hand,I still like to discuss
your way to got it.
********************************************************************
=============filename:edit.php============(This way is OK!)====================>begin
<?$news=file('this.txt');
$num=count($news);
echo "<TABLE>";
for($i=0;$i<$num;$i++)
{
echo "<tr><td>".$news[$i]."</td><td><a
href=myphpmail.php?action=del&line=$i>DELETE THIS LINE</a></td></tr>";
}
echo "</table>ok";
if($action=='del')
{
unset($news[$line]);
$news=implode("",$news);
$fp=fopen('this.txt',"w");
fputs($fp,$news);
} ?>
<====================================end
