I am using some code to insert a string into a database but split it up using . or , or spaces etc
BUT I am getting an error.

Could anyone help?

$string=$answer;
					
	// get the input string from the post and then tokenize it to get each word, save the words in an array  in case the word is repeated add '1' to the existing words counter
	$count=0;
	$tok = strtok($string, " \t,;.\'\"!&-`\n\r");//considering line-return,line-feed,white space,comma,ampersand,tab,etc... as word separator
	
	if(strlen($tok)>0) $tok=strtolower($tok);
	$words=array();
	$words[$tok]=1;
	while ($tok !== false) {
		//echo "Word=$tok<br />";
		$tok = strtok(" \t,;.\'\"!&-`\n\r");
		if(strlen($tok)>0) {
			$tok=strtolower($tok);
			if($words[$tok]>=1){
				$words[$tok]=$words[$tok] + 1;
			} else {
				$words[$tok]=1;
			}
		}
	}

I am testing inserting aaa.bbb.

Error:
<b>Notice</b>:  Undefined index: bbb in <b>/Users/steve/Sites/stinteractive/v2.9/touch/library/votingProcess.php</b> on line <b>256</b><br />


Any ideas??

Many Thanks

Steve

Well, obviously the array is not formed as expe the or your code is wrong, but it's difficult to say without seeing the code. Please post it here.

try this:

$string="Now is the time for all good men to come to the aid of their country";
	$words=array();
					
	// get the input string from the post and then tokenize it to get each word, save the words in an array  in case the word is repeated add '1' to the existing words counter
	$tok = strtok($string, " \t,;.\'\"!&-`\n\r");//considering line-return,line-feed,white space,comma,ampersand,tab,etc... as word separator
	
	if($tok) $words[$tok]=1;
	while ($tok !== false) {
		//echo "Word=$tok<br />";
		$tok = strtok(" \t,;.\'\"!&-`\n\r");
			if(isset($words[$tok])){
				$words[$tok]++;
			} else {
				$words[$tok]=1;
			}
		}
var_dump($words);

Hi,

Ive tried the suggested code and it works BUT I get a 0 at the end:

array(14) {
  ["is"]=>
  int(1)
  ["the"]=>
  int(2)
  ["time"]=>
  int(1)
  ["for"]=>
  int(1)
  ["all"]=>
  int(1)
  ["good"]=>
  int(1)
  ["men"]=>
  int(1)
  ["to"]=>
  int(2)
  ["come"]=>
  int(1)
  ["aid"]=>
  int(1)
  ["of"]=>
  int(1)
  ["their"]=>
  int(1)
  ["country"]=>
  int(1)
  [0]=>
  int(1)
}


What's the best way to loose this??

Sure. Just move the test inside the loop..

$string="Now is the time for all good men to come to the aid of their country";
	$words=array();
					
	// get the input string from the post and then tokenize it to get each word, save the words in an array  in case the word is repeated add '1' to the existing words counter
	$tok = strtok($string, " \t,;.\'\"!&-`\n\r");//considering line-return,line-feed,white space,comma,ampersand,tab,etc... as word separator
	
	while ($tok !== false) {
	if($tok) $words[$tok]=1;

			if(isset($words[$tok])){
				$words[$tok]++;
			} else {
				$words[$tok]=1;
			}
				$tok = strtok(" \t,;.\'\"!&-`\n\r");
		}
var_dump($words);
