PHP regular expressions

[menwn]

Hello all,

 

My question is this. How can one with a regular expression to guarantee that at least on digits exists in a string.

 

Valid Example: ABdafd123

 

Invalid Example: ABCfgssf

 

Thank you

Not great with regex but i think this will work

preg_match('/[0-9]/', $text)

 

edit do note that it will only check if it has a digit in it. It will not check if the remaining chars are letters

Thank you for your reply.

 

I want to disable the ability to pass not alphanumeric characters. And this does not help a lot.

 

Up to now I had: preg_match("/[^a-zA-Zα-ωΑ-Ω0-9]/", $text)

 

It works ok but I can pass all letter strings which I want to forbid unless it has at least a digit in it.

 

thanks

if (!preg_match('/[\d]+/', $text)) {
    print 'No digits!';
}

MrAdam, you don't need the + sign or the brackets. If it matches any single number, there's a digit so you don't need to check for more.

Ahh of course!
