No output after mysql_connect

[Dinesh Kumar]

 Hi MySQLers
 
 I have written following script:
 ----------------------------------------------------------------------
 <?php
 echo 'Hello World';
 $con = mysql_connect('localhost', 'dinesh', 'dinesh');
 if (!$con)
 {
     die('Could not connect: ' . mysql_error());
 }
 echo 'connected';
 ?>
 
 ------------------------------------------------------------------------
 On execute, I find that 'Hello World' only is printed.
 no code below mysql_connect function call get executed.
 I do not get the errormessage also. Hence I do not know whether I am 
 connected.
 Bytheway, I am able to connect through commandline interface using given
 username and password.
 
 Please help.
 
 Regards
 
 Dinesh
