help with implode

[MDanz]

when i echo count($words) it is 1.

 

but when i print_r($itemid)  it displays this.. 

Array ( [2] => 17 [3] => 15 [4] => 17 )

 

when i count($words) it should echo 3.

 

print_r($itemid);
$words = implode(" ", $itemid);

echo count($words);

You are imploding the array into a string then using count on it, which should be used on arrays. If you wish to count the values you need to do it before using implode

You can also have a look at str_word_count(). It may work for you.

@OP

$words = implode(" ", $itemid);

echo count($itemid);

 

Would also work.

 

@Pikachu

For the purpose of this function, 'word' is defined as a locale dependent  string containing alphabetic characters, which also may contain, but not start  with "'" and "-" characters.

 

Array ( [2] => 17 [3] => 15 [4] => 17 )

thanks for the help.

 

could i have help on this.

 

 

$oldarray = implode(" ", $itemid);

$newarray = explode(" ", $oldarray);

i have to do the above to reset the array index to start at zero.

 

how do i set a session array for $newarray? 

 

e.g. $newarray = 13 14 15

 

so i want the  session array to be

[0] =>13
[1] =>14
[2] =>15

Use array_values

$arrItemId= array_values($itemid);

 

$_SESSION['desiredSessionName'] = $arrItemId;
echo '<pre>' . print_r($_SESSION['desiredSessionName'], true) . '</pre>'; //to see result

[MDanz]

thanks alot... i tried array_values before but didn't get desired results.... thanks

Somehow when I read that, my mind saw 'alphanumeric'. Alphabetic definitely makes more sense, though. LOL.

lol easy mistake to make. I would've missed it too if I didn't remember the example with 'fri3nd' split into 2 words.
