[SOLVED] String Length

[Kingy]

Ok i have 3 varibles that i want to join together and then i want it to count them.

 

<?php
       $string = "$ex[3] "." $ex[4] "." $ex[5]";
       $string = trim($string);
       $length = strlen($string);
      
       echo $string;
       echo $length;
?>

 

if i use the example

 

`string hello my name is kingy

it returns

 

`string hello my name is kingy

32

 

But if you count, there should only be 30 characters :s

You could have extra spaces btween the words. trim() only removes from the ends.

oh yeah i think i see now the output is actually

 

String: `string  hello  my name is kingy

 

2 spaces either side of hello... how do i fix this :s

 

`string = $ex[3]

hello = $ex[4]

my name is kingy = $ex[5]

 

so i have stuffed up my spaces in between the $ex somehow

[revraz]

Change the spaces here

 

$string = "$ex[3] "."$ex[4] "."$ex[5]";

Try this:

 

<?php
       $string = "$ex[3] "." $ex[4] "." $ex[5]";
       $string = trim($string);
       $exp = explode(" ",$string);
       $len = 0;
       foreach($exp as $val){
              $len += strlen($val);
       }
       echo $string;
       echo $len;
?>
