Converting Double Quotes

See example URL. Enter anything surrounded in double quotes, for example, "this is a test". Click "Do It". See the result.

I don't want php to automatically insert the escape (\) before the ". How can that be avoided?

See attached code for php in 2nd script.
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

<?php

function elim_quotes($x) {

	$res = "";

	$n = strlen($x);

	for ($i = 0; $i < $n; $i++) {

		$ch = substr($x,$i,1);

		if ($ch == chr(34)) {

			$res = $res . "``";

		} else {	

			if ($ch == chr(39)) {

				$res = $res . "`";

			} else {

				$res = $res . $ch;	

			}

		}

	}

	return $res;

}				

?>

<html>

<head>

	<title>Test elim quotes</title>

</head>
 

<body>

Value from form = <? print $val; ?><br>

<? $newval = elim_quotes($val); ?>

Converted value = <? print $newval; ?><br>
 
 

</body>

</html>

BTW: if you want to disable that ("auto-escaping") feature completely  throughout the server, in you php.ini file you would need this:
magic_quotes_gpc = Off
