PHP新行 和 无效

Question

  $rows = mysql_num_rows($result) ;
  for ($j=0 ; $j < 3 ; $j++) {
  for ($i=0 ; $i < 3 ; $i++) {
    $row = mysql_fetch_array($result) ;
    echo '<a href="image2.php?id='.$row['ID'].'">'."<img src='".$row['Image']."' />".'</a>' ;

  }
   echo "
";
  }

The code displays three groups of three images. My understanding was that and (double quotes) should create a new line. However it is just inserting a space between the images. Is the way am callign wrong or is it am using the wrong code to isneert a new line (line break)

Examples (# = one image):

Without echo : ######### With echo : ### ### ###

Answer 1

Your echo " "; is outside the loop. Move it inside the loop.

Also, if you want the line breaks to be visible in the browser, you should print a <br /> too.

  $rows = mysql_num_rows($result) ;
  for ($j=0 ; $j < 3 ; $j++) {
  for ($i=0 ; $i < 3 ; $i++) {
    $row = mysql_fetch_array($result) ;
    echo '<a href="image2.php?id='.$row['ID'].'">'."<img src='".$row['Image']."' />".'</a>' ;
  }
    echo "<br />
";    
  }
