Detecting extension

If anyone has the experience, how could I obtain the image extension, and if it's swf to do something else? Remote image, and I'm using php4.
One more thing, the link is stored in a database.
if I'll do a preg match, there will be a risk, that the image to contain 2 or more times 2 different words, giving an error.

example(doesn't work) h ttp://upload.wikimedia.org/imagif/page.swf

 

nvm, I figured out how to.

 

In case anyone else is wondering or you want something succinct.

You can use the pathinfo function to accomplish this.

 

post ur solution to make this thread more beneficial for other or just ask the MOD to delete it ...

 

$name = $database['filename'];
$extension = end(explode('.',$name));

PHP:

Peace,

 

//$pimp[8] is the query
$pro=strrchr($pimp[8],'.');
if($pro == ".swf")
{ //flash 
} 
else{//image 
}

PHP:

 

Your code will not work if the URL contains another "." in it.

Peace,

 

oh, you're right azizny, thanks for helping me.

 

Or just create a function:

function get_file_extension($file)
{
    $ext = explode(".", $file);
    $extcount = count($ext);
    return strtolower($ext[$extcount - 1]);
}

PHP:

$file = "name.swf";
$extension = get_file_extension($file);

if ( $extension == "swf" )
{
// Extension is SWF so execute code
}

PHP:
