What a stupid function!!!
| | | | Erling Jepsen wrote : 927
From the PHP manual:
------
Description
bool file_exists ( string filename)
Returns TRUE if the file specified by filename exists; FALSE otherwise.
------
So now - why do we need this function? - It`s Stupid.

where is the value added?
| | | | Sarah King wrote : 929
this has blantantly been added because of the competition. Who approves/moderates these things.

What a stupid function. I can`t believe that somebody can waste he time doing that kind of thing. You don`t even need to be a good programmer for that, just use your common sence.

Indeed, I take full responsibility for moderating (NOT) this. It will be removed in a few days (So people will not get a not found message and mail to ask what was all the fuss about :). As for the competition, it has proved to be a blessing to us all since many new code examples were added (for both novice and advanced users).
Take a look at the number of people that had something to say about this example and the number of people that gave it a grade of 1. This has certainly spiced up the mood on the site :)
I may just leave this example for people to see and learn what not to submit.

ive got another function for you all -
function is_set($variable) {
if(isset($variable)) {
return true;
else {
return false;
}
}
// see if a variable exists
if (is_set($variable)) {
echo "yes, it exists";
} else {
echo "no, it doesn`t exist";
}
enjoy :-)

ok - point taken - it is a very stupid function which i added by mistake (a copy and paste from old code).
but hey.... im sure it got a few laughs!!

I decided to leave this example as an example to what NOT to post :). I`m linking to it from the add example page.

I`ve optimized this function:
function file_exist($filename) {
return file_exists($filename)
}
It`s a lot faster :D
