scan for line/lines starting with input text

[e39m5]

i have 2 input text boxes, 1 named deletel other deleta "l" means last and "a" means all. If a name is entered into deletel i want to scan shouts.php starting from the bottom and the first line it finds that starts with the name entered in deletel and delete it. it has to be starting from the bottom. For deletea i want to scan shouts.php for all lines that start with the name entered in deletea and delete them all. if you have one solution but not the other post it, i need these codes asap.

I would do something like this:

$filedata = file("shouts.php") || die("Failed");
$filedata = array_reverse($filedata);
if(isset($_POST['deletel']) && $_POST['deletel'] != ''){
  for($i=0;$i<count($filedata);$i++){
    if(preg_match("/".$_POST['deletel'].".*?/", $value)){
      unset($filedata[$i])
      return 0; // Do something useful here,
    }
    $i++;
  }
}elseif(isset($_POST['deletea']) && $_POST['deletea'] != ''){
  for($i=0;$i<count($filedata);$i++){
    if(preg_match("/".$_POST['deletea].".*?/", $value)){
      unset($filedata[$i]);
    }
    $i++;
  }
}
$filedata = join("\n", $filedata);
$fhandle = fopen("shouts.php", "w+");
$fputs($filedata);
fclose($fhandle);

Probably lots of parse errors, I haven't tested the above.

Thinking about it you could just have one loop and check for deletea or deletel and the relevant point 🙂

I mean that since you have found what your looking for the procedure should exit, so if the code is a function it should return something...whatever you need to do 🙂
