you can use PHP functions as well

if( strlen($string)>1 && ctype_alnum($string) ){
  print "ok\n";
}

use preg_match function 

 
$str ="1234a";
if ( preg_match ( '/[A-Za-z]{1,}/',$str ,$val ) ) 
{ 
print "right" ; 
print_r ( $val ) ;
} 
else 
{ 
print "wrong " ; 
}

It prints right;

If you're inputting a word at a time then simply check:

[a-zA-Z]

because if you find a letter it's a word. If you have a stream of words it gets a little more difficult.

To find words that contain at least one letter:

\b([a-zA-Z0-9]*[a-zA-Z][a-zA-Z0-9]*)\b
