将值添加到PHP数组

Question

我打印时

foreach ($result_target AS $target) {
    $code_target = substr($target['code'], 4);
    if ($code_source === $code_target) {
        if ($source['quantity'] !== $target['quantity']) {
            print $source['quantity'] .' -> ' . $target['quantity']."<br /><br />";
            $match[] = array('code' => $source['code'], 'quantity' => $source['quantity'], 'targetid' => $target['id'], 'sourceid' => $source['id']);      
        }
        $found = true;
        break;
    }
}

我有这样的结果：http://suszek.info/projekt1/就像你看到有50个值。当我打印$ match时，会有更多，重复的值，我不知道为什么？

$msg = '';
foreach ($match AS $entry) {
    $msg .= 'Change identified: Home_ID=' . $entry['sourceid'] . ' code: ' . $entry['code'] . ' quantity:' . $entry['quantity'] . PHP_EOL . '<br />';
    print $msg;
    /*  Perform DB updates using $entry['targetid'] and $entry['quantity'] */
}

我有这样的结果：http://suszek.info/projekt1/index_1.php所有代码：

 $match = array(); $new = array();

 foreach ($result_source AS $source) {

     $found = false;
     $code_source = substr($source['code'], 4);
     foreach ($result_target AS $target) {
         $code_target = substr($target['code'], 4);
         if ($code_source === $code_target) {
             if ($source['quantity'] !== $target['quantity']) {
                 print $source['quantity'] .' -> ' . $target['quantity']."<br /><br />";
                 $match[] = array('code' => $source['code'], 'quantity' => $source['quantity'], 'targetid' => $target['id'], 'sourceid' => $source['id']);      
             }
             $found = true;
             break;
         }
     }

     if (!$found) {
         $new[] = array('code' => $source['code'], 'quantity' => $source['quantity'], 'sourceid' => $source['id']);
     } } $msg = ''; foreach ($match AS $entry) {
     $msg .= 'Change identified: Home_ID=' . $entry['sourceid'] . ' code: ' . $entry['code'] . ' quantity:' . $entry['quantity'] . PHP_EOL
 . '<br />';
     print $msg;
     /*  Perform DB updates using $entry['targetid'] and $entry['quantity'] */ }

 foreach ($new AS $entry) {
     $msg .= 'New Entry: Home_ID=' . $entry['sourceid'] . ' code: ' . $entry['code'] . ' quantity:' . $entry['quantity'] . PHP_EOL . '<br
 />';
     #print $msg;
     /*  Perform DB inserts using $entry['code'] and $entry['quantity'] if this is desired behaviour */ }

 /*  Send email with $msg  */

问题出在哪里？为什么$ match给我不同的输出

print $source['quantity'] .' -> ' . $target['quantity']."<br /><br />";
