I ran your code and got the correct results:

PHP Code:


		
			
<?php

function check_string($Valstring) {

    $ValResult=0;

preg_match_all('/^[a-zA-Z- .,]{2,200}$/', $Valstring, $matches);

    foreach($matches[0] as $value){

        if($value!='' || $value!='0' || $value!='null'){

            $ValResult=1;

         }  

         else{

            $ValResult=0;

         }          

    }

     return $ValResult; 

}



$array = array("hulu", "hulu-", "hulu123", "hulu]", "hulu+");

foreach ( $array AS $Valstring ) {

    echo "$Valstring has a result of " . check_string($Valstring) . "\n";

}

?>

However, this is a very inefficient way of doing this. A better function:

PHP Code:


		
			
<?php

function check_string($Valstring) {

    if ( preg_match('/^[a-zA-Z .,-]{2,200}$/', $Valstring) ) {

        return 1;

    }

    return 0; 

}



$array = array("hulu", "hulu-", "hulu123", "hulu]", "hulu+");

foreach ( $array AS $Valstring ) {

    echo "$Valstring has a result of " . check_string($Valstring) . "\n";

}

?>

Both of these output:

Code:

hulu has a result of 1
hulu- has a result of 1
hulu123 has a result of 0
hulu] has a result of 0
hulu+ has a result of 0
