Help with separating a text string.

[Parobola]

Hello again, I have a problem I need to overcome and cannot fathom how.

 

I need to take a random length character string i.e. "This is a sample of what I need to accomplish."

 

Then I need to separate the character string into lengths that won't push past the boundaries of a FPDF cell.  This is easy to do using strlen( ); but if I seperate by string length then I will end up with part of a word one line and part of another word on another line. 

 

So what I thought I would do is separate the words using explode(" " , $string); and dump it into an array.  Then pull out each word, add it to a string, and use strlen( ); to check my length and use IF (strlen($string) >= 10) {start a new line} ELSE {add another word from array and restart test}.

 

My issue is that I can't figure out how to use the explode function with the array function properly.  Any advice on where I can look, or anyone want to give me an example of how I could accomplish this?

wordwrap

$string = "this is a sample string for learning";
$exp = explode(" ",$string);
foreach($exp as $value){
   if(strlen($value) >= 10){
       //do something
   }else{
       // do something else
   }
}

 

since I do not fully understand what exactly you are wanting to do to the strings if they are under 10 chars and above 10 chars, I can't quite finish this code...if you need further help let me know.

 

Edit: wordwrap could be what you want here yes..
