Question about an array

I want to create an array with some text. Let's say the following: $sometext = array(explode(" ", "Objective: Position as a Machine Attendant and or Operator Summary - Over 16 years experience in packaging and maintenance of various operating machinery. - 13 years experience in cutting steel and operating a steel press. - Part time experience in packaging and shipping bread for a bakery.")); I can easily return that text using: print_r($sometext); However I want loop through that text for to bold certain words in the array. In any event I've tried using the following but it only returns "sometext at[0] is: [Array]" which is not want I want, I want it to show me each word in the array through the loop. Any ideas what I am doing wrong? $arrayLength = count($sometext); for ($i = 0; $i < $arrayLength; $i++){ echo "sometext at[" . $i . "] is: [" .$sometext[$i] . "]<br>\n"; } Thanks
