Removing specific line in a text file selected from a list box.

[b0r3d]

Hey,

I cannot see exatly what im doing wrong here.. hopefully someone will be able to help out. I am trying to remove a specific ip address from a list box all all the data is stored in a flat text file "ips.txt" Example below.

Say this is the list.

1.1.1.1
2.2.2.2
3.3.3.3
4.4.4.4
5.5.5.5

IF i select to remove 4.4.4.4 i want it to be
removed from the text file.

if ($action == "remove") {

                 $file = "ips.txt";
     $file2 = "ips2.txt";
     copy("$file","$file2");
                 unlink("$file");
     $finput=file("$file2");
     $foutput=fopen("$file","a+");
     $i=0;
          while ($i < count($finput)):
                if ($ips == $finput[$i]) {
                     fwrite($foutput,$finput[$i++]);			          $i++;
	}
     fwrite($foutput,$finput[$i]);
               $i++;
     endwhile;
                 fclose($foutput);
     unlink("$file2");

     }

Assuming $ips is the selected value to be deleted then you need to get rid of a couple of '++'s and change the if... test.

if ($action == "remove") {

     $file = "ips.txt";
     $file2 = "ips2.txt";
     copy("$file","$file2");
     unlink("$file");
     $finput=file("$file2");
     $foutput=fopen("$file","w");
     $i=0;
     while ($i < count($finput)) {
                if ($ips != $finput[$i]) 
                        fwrite($foutput,$finput[$i]);
                $i++;
     }
     fclose($foutput);
     unlink("$file2");

}

For some reason everything seems alright here.. but yet it will not work at all what so ever.. !!! its driving me nuts..

You can try it here..

Doesn't give me any errors but it doesn't remove the selected ip either..

		if ($action == "remove") { 

		$file = "ips.txt"; 
		$file2 = "ips2.txt"; 
		copy("$file","$file2"); 
		unlink("$file"); 
		$finput=file("$file2"); 

		$foutput=fopen("$file","w"); 
		$i=0; 
			while ($i < count($finput)) { 
				if ($ips != $finput[$i]) 
					fwrite($foutput,$finput[$i]); 
					$i++; 
				} 
		fclose($foutput); 
		unlink("$file2"); 
		?>
		<META HTTP-EQUIV=Refresh CONTENT="0; URL=<?php echo "http://$url"; ?>">
		<?php

	}

Thanks in advanced

When it runs, what is the value of the variable $ips?

[b0r3d]

$ips is the value of the list box.. when an ip is selected from the listbox..

this is the stuff from that file..

	echo "<select size=10 name=ips>";

while (!feof ($fp) ) {       
	$domain = fgets($fp,filesize("ips.txt"));
	$chop = chop($domain);

	echo "<option value=$chop>$chop</option>";

	$line = $line + 1;
}
	echo "</select>";
fclose($fp);
