Associative array - Foreach

[curb]

I made a foreach to find the value for the sentence and it works if the ID matches the sentence.

But how would I find the value by entering keywords so the associative array would have a value if it contains "jo" and "canc" instead of "jo canc"?

<?php
  $sentence = "john donated $1000 to breast cancer research.";
  $names["jo canc"] = john_1;
  $names["jo work"] = john_2;

  foreach ($names as $keyword => $value) {
      if (!strpos($sentence, $keyword) === false) {
          echo $value;
		  //will echo john_1
      }
  }
?>

sounds like you need a multidimensional array something like this:

	$foo=array(
		array(
		'sentence' => 'John donated $1000 to breast cancer research',
		'canc' =>'john_1',
		'work' =>'john_2'
		),
		array(
		'sentence' => ' ',
		'canc' =>'',
		'work' =>''
		)
	)

Sentence 1 pulls the word "jazz" and sentence 2 does the same. How can I setup the array or foreach so it can search for "Word AND Word" and not "Word OR Word"

//THIS WILL PULL "JAZZ"
$sentence1 = "My buddy plays the trumpet while I'm jamming with a flute.";

//THIS WILL PULL "JAZZ"
$sentence2 = "My neighbor sold me his trumpet.";


$niches = array(
  'jazz'=>array(
    'jazz',
    'trumpet',
    'drums',
    'flute'
  ),

);


foreach( $niches as $singer=>$songs )
{
  asort( $songs );
  foreach( $songs as $song )
  {
   if (!strpos($sentence1, $song) === false) {
          $niche = $singer;
      } 
  }
}
