( ! ) Parse error: syntax error, unexpected ''/('' (T_CONSTANT_ENCAPSED_STRING) in C:\wamp\www\yeah.php on line 3

Is it possbile on regex ..If its possible please tell me how ..

Answer 1

My recommendation would be to use an already set up function, such as urlencode() to escape data for inclusion in a URL. For more info, see this page: http://us1.php.net/urlencode
