change file extension

[denoteone]

I have a file that has any file extension. I want to change that to a .flv  below is what I have so far.

$newfile = myvideo.avi;

//I need to find and replace what ever is after the "." with flv I know it is some thing like:


$file_name_array = explode($newfile,".")

$file_name_array[1] = "flv";

$final_name = file_name_array[0] .  file_name_array[1] 

echo $final_name;

The output will be     myvideo.flv

You have the explode the wrong way around

 

should be

 

$file_name_array = explode(".", $newfile);

 

and

$final_name = $file_name_array[0].".".$file_name_array[1];  //was missing $ and correct concatenation

 

Don't forget your semicolons at the ends of the lines

I am probably WAY off mark here, but wouldnt this also work?

  $file_name = $file_name_array['0'];
  $new_name = str_replace($substr($file_name, -3, 3), 'flv', $file_name);

You do not even have to place the name in an array to do it this way.

 

Simply

$file_name = 'myvideo.avi';
$new_name = str_replace(substr($file_name, -3, 3), 'flv', $file_name);

 

That would work.  The limitation here is that it will only work with file extensions of 3 characters in length.  And remember, no $ in front of the substr function name.
