Jason Wong,您好！
As you know,I'm a newbie in PHP,I tried your way last night,but to my surprise,it do
nothing for any way,it didn't delete any line in the TXT-file,even the file
"outputfile.txt" indeed!
Perhaps it because that I haven't understand your thought and absolutely copy your
words to the program,but,can you give me more help?
After I write "del.php" copy your words,I'v been trying to edit my manage file
"edit.php" as follow:
---filename:edit.php------------>
<?
$news=file('this.txt');
$num=count($news);
$fp=fopen('outputfile','w');
echo "<TABLE>";
for($i=0;$i<$num;$i++){
echo "<tr><td>".$news[$i]."</td><td><a
href=edit.php?action=del>删除此行</a></td></tr>";
if($action!='del')[EMAIL PROTECTED]($fp,$news[$i]);
}
echo "</table>ok";
fclose($fp);?>
<--------------------------------
I think this will work as my willings,but it not!
It's troubling so long.I need more help.
Thanks a lot,my friend!
