Check if file existes

[dandandan]

whats a function/way that i can check if a file exists? eg:

$number="1";
$filename="test";

untill (A FILE NAMED $filename$number.txt DOES NOT EXIST) {
$number++
}


Thats main idea of what i want to use it for, i just dont know what function to use.

[Hi I Am Timbo]

I would try the file_exists() function

[Hi I Am Timbo]

[code]
<?php
$number="1";
$filename="test";

while(file_exists($filename$number.txt))
{
    $number++;
}
?>
[/code]

though you would want to add some code in there to do something to the file because the example will add indefinately.....

[Hi I Am Timbo]

I don't think it will.  It will not do anything, but it will not be an infinite loop.  It will add until the file doesn't exist, doing nothing each time.

slight modification to your code Timbo:

[code=php:0]
<?php
$number="1";
$filename="test";

while(!file_exists($filename.$number.'.txt'))
{
    $number++;
}
?>
[/code]

you forgot the ! in the condition, and a . between your $filename and $number, and also forgot some quotes for the .txt

[Hi I Am Timbo]

yes, thank you.

[Hi I Am Timbo]

Actually, the ! shouldn't be there.  I think they wanted to do something to all files until they don't exist anymore.  But I did forget the .

okay yes you are right about the !
