Code:

<?php ini_set('display_errors', 0);
error_reporting(E_ERROR | E_WARNING | E_PARSE);  ?><centeR><table border="1"><tr><td align="center" colspan="2"><form action="#" method="post"> 
<select name="language">
<option value="html">HTML</option>

<option value="php">PHP</option>
 </select></td></tr><br><tr><td>
<textarea cols="25" rows="25" name="code" value=""></textarea></td> <td>


<?php 

//echo getcwd();

if(isset($_POST['sbt1']) && ($_POST['language']) == "php" )
 { 
 		//echo "hello";
		$code = $_POST['code'];
		
		 $myfile = fopen("testfile1.php", "w");
		$write_file = fwrite($myfile , "$code");
								} 
								
if(isset($_POST['sbt1']) && ($_POST['language']) == "html" )
 { 
 		//echo "hello";
		$code = $_POST['code'];
		
		 $myfile = fopen("testfile1.html", "w");
		$write_file = fwrite($myfile , "$code");
