I am not writing it but I need to process the file. I should be more clear.

I have a file named filename.txt already in the folder

Now the requirement is :


Now I get another file with same name filename.txt .


So my code will be like this

if the file with name filename.txt already exists
then
append the contents of the new file into the old file without the header.

I hope im clear.

Since this situation will occur multiple times I beleieve I have to use "for do" loop

I am stuck with the same filename append part.

filesize - Gets file size

SYNOPSIS
int filesize (string $filename) DESCRIPTION
Gets the size for the given file. PARAMETERS
o $filename - Path to the file. RETURN VALUES
Returns the size of the file in bytes, or FALSE (and generates an error of level E_WARNING) in case of an error. Note Because PHP's integer type is signed and many platforms use 32bit integers, some filesystem functions may return unexpected results for files which are larger than 2GB. EXAMPLES
Example #1 filesize(3) example <?php // outputs e.g. somefile.txt: 1024 bytes $filename = 'somefile.txt'; echo $filename . ': ' . filesize($filename) . ' bytes'; ?> ERRORS
/EXCEPTIONS Upon failure, an E_WARNING is emitted. NOTES
Note The results of this function are cached. See clearstatcache(3) for more details. Tip As of PHP 5.0.0, this function can also be used with some URL wrappers. Refer to "Supported Protocols and Wrappers" to determine which wrappers support stat(3) family of functionality. SEE ALSO
file_exists(3). PHP Documentation Group FILESIZE(3)
