Array von Funktion zurückgeben php

Question

Ich brauche diese Funktion, um ein Array zurückzugeben. Wenn ich die Funktion anrufe, druckt es das Array, aber wenn ich return $finalResult in der Funktion verwende, druckt es nur das erste Array.

function readData($file) 
{ 
    $finalResult = array(); 
    $inputText = file_get_contents($file); 
    $textLines = explode("\n", $inputText); 
    foreach ($textLines as $line) 
    { 
     $expLine = explode("\t", $line); 
     if (count($expLine) < 8) 
     { 
      # The line does not have enough items, deal with error 
      //echo "Item " . (isset($expLine[0]) ? $expLine[0]." " : "") . "ignored    because of errors\n"; 
      continue; 
     } 
     $finalResult = array(
      "title" => $expLine[0], 
      "author" => $expLine[1], 
      "isbn" => $expLine[2], 
      "hardcover" => $expLine[3], 
      "hc-quantity" => $expLine[4], 
      "softcover" => $expLine[5], 
      "sc-quantity" => $expLine[6], 
      "e-book" => $expLine[7], 
     ); 
     $arr = $finalResult; 
     print_r($arr); 
    } 
}

Wie in meinem Kommentar oben beschrieben

function readData($file){ 

    $arr   = array(); 
    $finalResult = array(); 
    $inputText = file_get_contents($file); 
    $textLines = explode("\n", $inputText); 

    foreach($textLines as $line) { 
     $expLine = explode("\t", $line); 
     if (count($expLine) < 8) { 
      # The line does not have enough items, deal with error 
      //echo "Item " . (isset($expLine[0]) ? $expLine[0]." " : "") . "ignored    because of errors\n"; 
      continue; 
     } 
     $finalResult = array(
      "title" =>$expLine[0], 
      "author"  => $expLine[1], 
      "isbn"  => $expLine[2], 
      "hardcover" => $expLine[3], 
      "hc-quantity" => $expLine[4], 
      "softcover" => $expLine[5], 
      "sc-quantity" => $expLine[6], 
      "e-book"  => $expLine[7], 
     ); 
     $arr=array_merge($arr, $finalResult); 
    } 

    return $arr; 
}
