php file?

[dezkit]

is there a way that i can do that if the file is png, jpg, jpeg, or bmp, the file displays as an image, but if its other, it displays as a link

so you want to tell if a file is a image?

 

<?php
    function getExt($str) {
        $i = strrpos($str,".");
        if (!$i) { return ""; }
        $l = strlen($str) - $i;
        $ext = substr($str,$i+1,$l);
        return $ext;
}
$var = $_POST['file'];
$file = getExt($var);

if ($file == ("png" || "jpeg" || "bmp" || "jpg")){
echo '<img src="$var" alt="Image" />';
}else{
echo '<a href="page.php">Page</a>';
}

?>

 

any help?

use the getimagesize() function to test to see if a file is really an image. Renaming wombat.exe as wombat.jpg will NOT make the file an image
