preg_match

[Dennis_Gull]

Hello, im trying to get preg_match to check if two characters exist in my input field but im not quite sure how it works. This is what I got

if(preg_match('/.@/' , $_POST['variable'])) {... 

This will be true if i have either . or @ but I wanna check if the post have them both, does anyone know how to do this?

Do it twice, once for each character.
In fact, just use strpos() instead.

[Dennis_Gull]

okay, guess i do that then

/.@/

This will match if you have an ampersand preceded by any character. I think you meant:

/[\.@]/

which would match if you had a dot or an @ symbol in the code. You could say:

/@.+?\./

- an @ symbol, some characters, and then a dot.

But if you wanted . then @ OR @ then ., you would still need two statements.

Hm... yes, I think so.

No. (@.*\.|\..+@)

EDIT:
( begins or statement
| separates choices
) ends or statement

[Dennis_Gull]

I haven't tried the code yet (i use two statements for now) but could someone tell me what all the characters do?
@ and / = start and end?
| separates?
\ * . + does?

Statements in a regular expression execute in the order they come. Brackets () are just a way of grouping a certain expression, the | character is simply a way of creating another statement within the same expression.

$found = strpos(".") && strpos("&") ? true : false;

Oh yes, I forgot about that.
