u need an english dictionary to test all possible values

[arpan.rnc]

no no .. i don't want to test it is a valid english word or not. i just want to test whether the string contains only "a-z,A-Z and other symbols" means it should not be using arabic,chinese or other such characters . What i want to block is something like this مقاطع سكس

thanx

ok thats what you ment

use regular expressions

$word = isset($_POST['word']) ? trim($_POST['word']) : '';

if(!preg_match("#^([a-zA-Z0-9_-+]+)$#", $word, $m))
{
   echo "invalid characters supplied";
}
else
{
   print_r($m); //matches that were found
}

Your welcome a better way to do this though to prevent mix characters

$error = 0;

$word  = isset($_POST['word']) trim($_POST['word']) : '';

for($i=0; $i<=strlen($word); $i++)
  {
     if(!preg_match("/([a-zA-Z0-9_-+])/", $word[$i], $m))
     {
       break;
       $error = 1;
     }
      
  } 

if($error==1)
{
  echo "incorrect word only aphanumeric chars";
}
else
{
  echo "you have passed the test";
}
//end

//end 

So if someone types a word in Serbian "zdravo" which means "hello" in English will pass the filter. Also, if someone writes "hello, how are you?" will not pass the filter. o.O

Try this:

$pspell_link = pspell_new("en");
$word = explode(" ", $message);
foreach($word as $k => $v) {
   if (pspell_check($pspell_link, $v)) {
      echo "spelled right";
   } else {
      echo "Sorry, wrong spelling";
   };
};

If you look clearly at what help was wanted you would have seen that the code i have written is exactly what was asked for, if he wanted english statements then i could have inlcuded commas etc, but what was was asked for is that the text box should only accept a-zA-z0-9, juts look keenly before you reply.

even though zdravo is sebian its still alpha chars so it would pass,

what this code really works good on is that it helps to prevent other special chars, like russian etc.

Me? Do u understand english well? Here is what he asked:

"hi wapmasters ,
can anybody tell me how can i allow only english test to be entered into a text box
or, if a text is entered in any other language how can i replace it with a blank space or empty string ?

thanx"

He did not asked for that what u have posted. Period.

function validChar($string){
$string = preg_replace("/[^A-Za-z0-9.,!@#$%^&*()-=_+]/","",$string);
return $string;
}

This is what he ment with "only in english":

$pspell_link = pspell_new("en"); 
$word = explode(" ", $message); 
foreach($word as $k => $v) { 
   if (pspell_check($pspell_link, $v)) { 
      echo "spelled right"; 
   } else { 
      echo "Sorry, wrong spelling"; 
   }; 
}; 

You, please, leave me alone, don't explain anything more. I do not want to discuss with you on this issue, but it seems that you just want to argue.
Cheers.
