Php ereg验证表格

Im validating a form and its easy to validate numbers, letters a-z and so on but when i got to the point where i need to validate a field which must contain only the characters (a-z and special characters such as öçğüiş) with at least one space only I am really stuck!

I tried the following and some other techniques without success:

function validateAlphaSpecial($value) {
    if (ereg("/^[\p{L}\s]+$/", $value, $regs)) {
           echo 'true';
         } else {
           echo 'false';
        } 
}

Has anyone got a solution for this. Thank you.

Ereg has been deprecated as of PHP 5.3.0 like others said and you shouldn't use EREG.

The snippet below fits your validating requirement: a-z and special characters such as öçğüiş with at least ONE SPACE.

if( preg_match("/[\p{L}]\s{1,}+/u", $value) > 0 ) {
    echo 'Valid';
} else {
    echo 'Not valid';
}

About /u modifier [ from documentation ] :

This modifier turns on additional functionality of PCRE that is incompatible with Perl. Pattern strings are treated as UTF-8.
