ereg to preg conversion

I'm a complete novice when it comes to regex. Could someone help me convert the following expression to preg?

ereg('[a-zA-Z0-9]+[[:punct:]]+', $password)

An explanation to accompany any solution would be especially useful!!!!

Solution

  • To answer your real question, you'd need to structure your code like:

    if ( preg_match( '/[a-z]+/', $password ) && 
  preg_match( '/[A-Z]+/', $password ) && 
  preg_match( '/[0-9]+/', $password ) && 
  preg_match( '/[[:punct:]]+/', $password ) ) ...

    If you wanted to ensure the presence of at least one lowercase letter, at least one uppercase letter, at least one digit, and at least one punctuation character in your password.
