[RESOLVED] REGEXP Problem

iceomnia

Hi Everyone,

I need a regular expression to 'preg_match' to return true if a $tring contains less than or equal to three words.

For example:


$string = 'Sony'; // true
$string = 'Sony Ericcson'; // true
$string = 'Allen & Heath'; // true
$string = 'Some three word string'; // true
$string = 'Some four word string'; // false

I am lost when it comes to regular expressions so could someone tell me what to put...


$bool = preg_match('/---HERE---/', $string);

Thanks in advance.

First thing that comes to mind is:

if(preg_match('/^\S*(\s+\S+){0,2}$/', $string)
{
   // 0 - 3 "words"
}

Change the "*" to a "+" if you want to exclude empty strings, e.g. have it match 1 - 3 words.

Why thank you so much, worked a treat!

That's why I like this forum!

I have actuallt done what you suggested and changed the * to a + becuase 0(zero) occurences of a word is also invalid, thanks for mentioning that.
