Save File

[Dysan]

The following code, reduces an MP3 file length to x seconds. How do I save this music file as a new mp3 file?

$f = fopen("Upload/".$row['Path'], "rb");
$trash = fread($f, 2488320);
echo fread($f, 245760);
$trash = null ;
fclose($f);

I can't guarantee if the file will work or not, but to save it you can just do this:

$f = fopen('Upload/' . $row['Path'], 'rb');
$trash = fread($f, 2488320);
$content = fread($f, 245760);
echo $content;
$trash = null ;
fclose($f);

$new_file_name = 'file.mp3';
$fh = fopen($new_file_name, 'wb') or die('Can't open file');
fwrite($fh, $content);
fclose($fh);

Is that what you wanted?

Yes, though I get the following error message. Why is this?

Parse error: syntax error, unexpected T_STRING in C:\Documents and Settings\User\Desktop\Xampp\htdocs\Shrink\Upload.php on line 14

<?php

if (($_FILES["file"]["type"] == "audio/mp3")
|| ($_FILES["file"]["type"] == "audio/x-mpeg"))
{
  $f = fopen('$_FILES["file"]["name"]', 'rb');
  $trash = fread($f, (386 * 1024 / 8) * $_POST[Start]);
  $content = fread($f, (386 * 1024 / 8) * $_POST[Stop]);
  echo $content;
  $trash = null ;
  fclose($f);

  $new_file_name = $_FILES["file"]["name"]. "(New)";
[B]  $fh = fopen($new_file_name, 'wb') or die('Can't open file');[/B]
  fwrite($fh, $content);
  fclose($fh);
}
else
{
  echo "Invalid file";
  echo $_FILES["file"]["type"];
}
?>

Using the

bbcode tags - as you should whenever you post PHP code - the problem becomes apparent (unescaped string delimiter):

<?php

if (($_FILES["file"]["type"] == "audio/mp3")
|| ($_FILES["file"]["type"] == "audio/x-mpeg"))
{
  $f = fopen('$_FILES["file"]["name"]', 'rb');
  $trash = fread($f, (386 * 1024 / 8) * $_POST[Start]);
  $content = fread($f, (386 * 1024 / 8) * $_POST[Stop]);
  echo $content;
  $trash = null ;
  fclose($f);

  $new_file_name = $_FILES["file"]["name"]. "(New)";
  $fh = fopen($new_file_name, 'wb') or die('Can't open file');
  fwrite($fh, $content);
  fclose($fh);
}
else
{
  echo "Invalid file";
  echo $_FILES["file"]["type"];
}
?>

Also note that if you're using PHP5, you can simply use the [man]file_put_contents/man function.
