check for space in string

[brem13]

how would i check for a space in a string?

if(str($values['username) == " ") doesnt work and I didnt think it would

Read strpos

 

if (strpos($values['username'], " ") !== false)

Another Way

 

if( false !== preg_match("/[ ]+/i",$some_string)){
  // It has space!!
}

 

Preg Match is very powerful and robust.

1. preg_match returns an int unless there's an error, which I doubt.

2. You don't need the [ and ] in the regexp.

3. preg_match uses regular expression which is more extensive than a simple string match. Though it's just a space.
