if with an array

VooDooRT

Ok, my lack of experiance with Arrays is seriously becoming a problem. I'm going to have to start studying a lot more on them.

However, how can I make an if statement to check if an array matches a variable...

$formats = array('gif','jpg', 'png', 'jpeg'); 
 $ext = preg_replace("/.*\./", "", $imagefile_name);
   if($ext != $formats){
  	echo("<font face=arial size=1 color=#333333>Sorry, you're trying to upload a file format that isn't allowed.  Please go back and try again");
  }
    else{

thanks in advance...ugh

I don't think that's really what I need. I just want to make sure that the $ext of the file uploading matches one of the $formats. in_array would probably just give me one at a time, no?

what I'm looking to do is see if any of the variables in $formats equals $ext.

I thought

if($ext != $formats){

would work, but it's always giving me the error saying that EXT is NOT equal to FORMATS. Even if they are.

in_array() is the correct function to use:

 $ext = preg_replace("/.*./", "", $imagefile_name); 
if(in_array($ext, $formats)){
  echo "File type is ok";
}else{
  echo "File type not ok";

in_array basically does a foreach() on your array and returns true if $arrayitem == $yourvalue

I think your regular expression might be a bit suspect

$ext = preg_replace("/.*?\\.(.*?)/si", "$1", $imagefile_name);

maybe better. Or use a PHP built-in function.
