i tried to make an array of words by preg_split but i need some helps on regular expression.

what is the best regular expression format for me!?

Answer 1

You can use \s+ to match one or more empty spaces, which includes newlines. Also, you could add a fourth parameter PREG_SPLIT_NO_EMPTY to exclude any matching spaces.

$foo = preg_split ("/\s+/", $text, 0, PREG_SPLIT_NO_EMPTY);

For more information, see preg_split().

Answer 2

if you have utf8 mode you can use this.

$array = preg_split( '/\p{Z}+/u ' , $text );
