Help required! Create a .txt file or skip if .txt file already exists

Scorpio___

Hello,

I am currently trying to write a favourites script which will store all the information on a .txt file using the following line of code,

$file = fopen("mytextfile.txt","w");

All works great apart from one tiny problem...

Every time i reload the page it re-creates the .txt file and deletes all the content.

I need the code to create a .txt file if one doesn't exist (and skip the creation if one does) then run the rest of my program.

My guess so far is this...
If 'text file' doesn't exist, create one then run rest of code.
If 'text file' does exist, simply run the rest of the code.

Any advice, please? 🙂

$file = fopen("mytextfile.txt","a");

$file = fopen("mytextfile.txt","a");
is indeed the right answer but a second way would be to use the file_exists function

if(!file_exists("something.txt"))

It wouldnt be the best way of solving this problem but its a useful function to be aware of.

Hi Al,

If you want to get technical, an other option would be is_file()

Very good, I wasnt aware of that one.

I usually use file_exists to check if images for products,users etc exist.

If not I display a general picture.

Hello,

Thanks guys, works great! 🙂

One more question if i may?

How can i add a variable to this,

$file = fopen("mytextfile.txt","a");

For example, allow several people to create their own file (eg. person1.txt, person2.txt, person3.txt, etc).

Many thanks in advance. 🙂

Use this example:

$file = "somefile";
$i = 10;
$filename = "mytext".$file.$i.".txt";


echo $filename;

$file = fopen($filename,"a");
