preg_match

How can I do a pattern that matches if there is A-Z, a-z, -, space

Need more info. Are those chars the only allowed, or do you just want to check if one of them are found in the string? Must the string have a minimum and/or maximum length? Can it consist of e.g. spaces only?

actually i want to control the name field from form

Did you totally overlook my questions?? Guessing:

 

<?php
if (preg_match('~^[a-z -]+$~iD', $str)) {
//the string contains only a-z, A-Z, hyphens and/or spaces, and is at least one char long
} else {
//the opposite
}
?>

how can you make it at least 2 characters long, would be awesome if you could explain the pattern, but not necessary

<?php
if (preg_match('~^[a-z -]{2,}$~iD', $str)) {
//the string contains only a-z, A-Z, hyphens and/or spaces, and is at least two chars long
} else {
//the opposite
}
?>

thank you very much, is pattern much longer if only the first letter of sentence can be big. No the first char, but first letters of sentences. If it will be longer like double or so then you don't have to waste your time.
