I am using this script to delete picture from my server. But at the same time I want to protect the files in my server. Not accidentally delete but I noticed that if I typed the file index.pHp
or index.Php
is deleted from my server. Although setting it will not delete why php or this method not know between lowercase and uppercase.
What is not done right?
<?php
error_reporting (0);
$thefile = $_GET ['filetodel'];
$filename = "$thefile";
//$filename = "picture1.jpg";
/*protect some files*/
if ($thefile=='index.php' or $thefile=='INDEX.PHP' or $thefile=='UPLOADS.ZIP' or $thefile=='uploads.zip' or $thefile=='del.php'or $thefile=='DEL.PHP' or $thefile==NULL or $thefile=='.htaccess' or $thefile=='.HTACCESS' )
{
exit("<h2>cannot delete $thefile</h2>");
}
if ($thefile=="$thefile")
{
if (file_exists($filename))
{
unlink ("$thefile");
echo "<h2> file $thefile is delete</h2>";
}
else
{
echo "<h2>The<br>";
echo "$filename<br>";
echo "Does not exist</h2>";
}
}
?>
