Uite o metoda simpla:   <?php  function strb($start, $end, $str) { 	$x = explode($start, $str); 	$x = explode($end, $x[2]); 	$x = $x[0];  	return $x; }  $file = file_get_contents(basename($_SERVER["PHP_SELF"])); $content = strb("<div id='copyright'>", "</div>", $file);  if($content == "© bt.ionut") 	echo "OK!\n"; else 	echo "Copyright removed!\n";  ?> <html> <head> <title>Test</title> </head> <body> <div id='copyright'>© bt.ionut</div> </body> </html>  Cu putina obfuscare l-ai putea chinui pe unu fara experienta care vrea sa-ti fure pagina.
