greetings...
i would like to ask if what is the shortcut code if something like;
<?php
function getFileExtension()
{
....
}
$filex = getFileExtension($_POST['file']);
$img = array('jpg','bmp','gif','png');
if ($filex = unknown_function($img))
{
...
}
?>
the unknown_function() is responsible to auto-validate the values in an array...
i encounter this in PHP website.. but can't find it now... i forgot the function name...
anybody?

Hi there camilord,
Are you just trying to get the file extension, so that you can decide if it's 'allowed' or 'not allowed'?
Also is the function getfileextension() your own, I presume so as it's not a predefined function, the nearest is: [uk.php.net ]
The easiest way to get the filetype is this:-
//imagine as the string is filename.jpg
$fileExt = strip_tags(strtolower($_POST['your_file']));//clean and convert to lower case
//get filetype
$ext = strstr($fileExt, ".");
echo $ext;
This will echo .jpg - note: it includes the . Ok!
Could shove this into a function:-
Note that if its always from a $_POST or a $_GET you don't need to pass it into a function as it is a superglobal, so by definition the array (if set) is available throughout the scope of your project, ie: accesible anywhere ;)
//for a var
function FileExt($input){
$ext = strstr(strtolower(strip_tags($input)), ".");
return $ext;
}
//for a $_POST
function FileExt(){
$ext = strstr(strtolower(strip_tags($_POST['your_file'])), ".");
return $ext;
}
One last thing, I think that $_POST['file'] may be reserved for doing file uploads($_FILES[][]), but I could be wrong there.
Cheers,
MRb
