View Full Version : str_word_count and colons
01-21-2004, 10:53 AM
I have used the function str_word_count to split a text into words but this function will ignore colons so that a string like this
is split into "ProperName" and "Fred"
I would like the colon included so that the result is
"ProperName:" and "Fred"
What would be a good way of doing that?

I think if you use the explode function the colons will remain (although i never tested it).
$string = 'ProperName: Fred';
$string_new = explode(" ", $string);
Hope this helps

The problem with explode() is that you get empty elements in the result array if the string contains words seperated by more than one space. Also, words seperated by line-breaks, tabs etc. are not distinguished either.
You can perform a split along word boundaries more precisely with preg_split:
$result = preg_split('/\s+/', $string, -1, PREG_SPLIT_NO_EMPTY);

Thanks I'll try them out and see if they do what I need. The strings I have do form sentences and paragraphs. I just want each word but to include the semicolon (and only the semicolon) if it's used.

Thanks to both of you for you help. Mordred you case was much what I was after. I had to delve into the ugly world of reg expr. But
$psmethod = preg_split('/[\s,.]+/', $string, -1, PREG_SPLIT_NO_EMPTY);
gave me what I was after
