referencing arrays in arrays

I have an array, $field, like following: Array ( [0] => Array ( [0] => Array ( [disp] => computer [index] => computer ) [1] => Array ( [disp] => or [index] => @or ) [2] => Array ( [disp] => title [index] => @at 1=4 term [name] => ti ) ) [1] => Array ( [0] => Array ( [disp] => human [index] => human) [1] => Array ( [disp] => or [index] => @or ) [2] =>Array ( [disp] => subject [index] => @at 1=5 term [name] => s ) ) [2] => Array ( [0] => Array ( [disp] => [index] => John) [1] => Array ( [disp] => or [index] => @or ) [2] => Array ( [disp] => tsd [index] => @at 1=5 term @at 7=44 term [name] => tsd) ) [3] => Array ( [0] => Array ( [disp] => [index] => Eric) [1] => and [2] => Array ( [disp] => subject [index] => @at 9=5 term [name] => s ) ) [4] => Array ( [0] => Array ( [disp] => [index] => Main) [1] => and [2] => Array ( [disp] => subject [index] => @at 9=5 term [name] => s ) ) [5] => Array ( [0] => Array ( [disp] => [index] => Dog) [1] => and [2] => Array ( [disp] => [index] => [name] => ) ) ) In each string, $field[$j][2]["index"] in the array, will I replace 'term' with the word in "{$field[$j][0]["index"]}". Why doesn't it work like this?: --------------------------- 1. for($j=0; $j<6; $j++){ 2. $temp =str_replace("term","{$field[$j][0]["index"]}","{$field[$j][2]["index"]}"); 3. echo "<br>temp: $temp"; 4. $field[$j][2]["index"]=$temp; 5. echo "<br>utskrift: ${$field[$j][2][index]}"; 6. } 7. echo "<br>field: <br>"; 8. print_r($field); ------------------------- Line 3 and 6 gives the same, and correct outprint, but in line 8 nothing is changes from how it looked before the loop. "term" is still term and not replaced. What am I doing wrong!?
