A VERY DIFFERENT word wrap problem

madhavr

i need a solution to do a wordwrap but not in the usual sense of displaying to the screen but actually printing to the printer using PHPs lesser known printer function.

the problem im having is to get a value which contains each line of the text when word wrapped and then pass it (in each line instance) to the printer_draw_text function which takes a text variable as an argument and some coordinates on where to display the text. this leads me on to the next problem i need to do this so the y co ordinates are incremented for every new line output since as i said earleier each variable is explicitly printed using the printer_draw_text which takes x and y co-ordinates.

to explain more easilt let me give an example of what i would like to do ....

$text = " one two three four";

maybe loop through the string and assign every n number of words to a temp variable $temp.

then printer_draw_text($handle, $temp, 10,10);

this is done for however many lines is required or however many times the loop is done through the string.

so upon printing out the paper will read...

one two
three four

get it??

i know it sounds easy but i think this ones a bit tricky maybe pros out there can help me here.

cheers

I'm not sure if printer_draw_text recognizes end-of-line breaks (\n) or (\r) so i will asume it doesn't.

$text = " one two three four five six seven eight nine"; 

$text = trim($text);

$temp = explode(" ",$text);

$x = 0;
for($i = 0; $i <= count($temp); $i++) {
   if(($i % 2) == 0) {
      if(!empty($temp[$i])) {
         $TxtArray[$x] = $temp[$i];
         }
      }
   else
   else
      {
      $TxtArray[$x] .= " ".$temp[$i];
      $x++;
      }
   }

That little code will split each word into two word array elements.

I guess you add a new line for each value now

to echo it out do this

foreach($TxtArray as $key => $val)
	{
	echo $key." ".$val."<br />";
	}

thanks very much this has helped me alot but i am wondering how i can change this to allow say around x number of words to appear one each line?

so for example if i want eight words then after the eighth word then a new line is started

just incase someone wanted to know how i got it too work
but at the moment only maximum of two words are allowed on each line.

foreach($TxtArray as $key => $val)
    {
  echo "printing ".$key." ".$val."<br />";
printer_draw_text($handle, $val, 2500, 1100+($key*100));
    }
