Validating strings using preg_match

PHP
1

hellos!..

I am trying to check that someone is inserting only strings in a textbox and I tried this code

//check region is okey for submission
		if ( !preg_match("/^[a-z]+[\\w.-]*$/i", $region) ){
    		$error[] = 'please enter a correct region, without numbers';
		}

now the problem is if a region has a space say Dar es Salaam still it says its an error…can someone please help me how to detect such regions.

So… add the whitespace sequence to your acceptable characters list?
