how to detect a whitespace on string in php program

Question

I want to do treatments on two strings, and I must to know if there are spaces to stop my treatment and move on to the rest of characters I tested that but it doesn't rule the problem :

 for ($i = 0; $i < $lenght; $i++) {

                    if($text[$i] <> '' && $mask[$i] <> ''){

                        $nbrcrypted = $stringtonumber[$text[$i]] + $stringtonumber[$mask[$i]];
                        $resultat .= $numbertostring[$nbrcrypted];
                    }else{

                        $indice = false;
                    }                    
                }

how can I achieve that, thank you in advance

Define "whitespace." Do you mean spaces only? Horizontal tabs? Carriage returns? Line feeds? — user895378

if($text[$i] <> '' && $mask[$i] <> ''){ is useless, use if($text[$i] !== ' ' && $mask[$i] !== ' '){ for spaces

I don't get what you're actually trying to do but if you want to test your string for whitespaces:

if ( strpos( $yourString, ' ' ) !== false )
    null; // string has whitespace(s)
