title: combine multiple GET values with same variable name into one string
body: <p>I have a form which sends lots of GET['var'] in a form.</p>
  
  <p>Ive worked out how to set it to send var[1]=data&amp;var[2]=some&amp;var[3]=thing etc etc</p>
  
  <p>but how do I catch each variable and combine it into one string, seperated with a ", "?</p>
  
  <p>so $var = data, some, thing</p>
  
  <p><strong>UPDATE</strong>: </p>
  
  <p>Sorry I should of mentioned I already have the function that implodes the string but I dont know how to combine all the Var[n]'s into one $var string.</p>
  
  <p>Hope this makes sense!</p>
  
  <p><strong>Solved!</strong></p>
  
  <p>Thanks Kazar, your first answer actually worked a treat! it required me altering my script a little but your way certainly makes sense to me now</p>
