Image.php中被零除的错误

在服务器上查看错误日志时，我不断看到错误：

PHP Warning:  Division by zero in /public_html/wp-content/themes/sass-wordpress-bootstrap-master/image.php on line 95

以下是发生错误的代码：

$imgmeta = wp_get_attachment_metadata( $id );

                    // Convert the shutter speed retrieve from database to fraction
                          if ((1 / $imgmeta[\'image_meta\'][\'shutter_speed\']) > 1)
                          {
                             if ((number_format((1 / $imgmeta[\'image_meta\'][\'shutter_speed\']), 1)) == 1.3
                             or number_format((1 / $imgmeta[\'image_meta\'][\'shutter_speed\']), 1) == 1.5
                             or number_format((1 / $imgmeta[\'image_meta\'][\'shutter_speed\']), 1) == 1.6
                             or number_format((1 / $imgmeta[\'image_meta\'][\'shutter_speed\']), 1) == 2.5){
                                $pshutter = "1/" . number_format((1 / $imgmeta[\'image_meta\'][\'shutter_speed\']), 1, \'.\', \'\') . " second";
                             }
                             else{
                               $pshutter = "1/" . number_format((1 / $imgmeta[\'image_meta\'][\'shutter_speed\']), 0, \'.\', \'\') . " second";
                             }
                          }
                          else{
                             $pshutter = $imgmeta[\'image_meta\'][\'shutter_speed\'] . " seconds";
                           }

我真的不知道什么时候会叫它。机器人是否会触发此错误？

$imgmeta = wp_get_attachment_metadata( $id ); $imgShutter = $imgmeta[\'image_meta\'][\'shutter_speed\']; // Convert the shutter speed retrieve from database to fraction if ($imgShutter > 0) { if ((1 / $imgmeta[\'image_meta\'][\'shutter_speed\']) > 1) { if ((number_format((1 / $imgmeta[\'image_meta\'][\'shutter_speed\']), 1)) == 1.3 or number_format((1 / $imgmeta[\'image_meta\'][\'shutter_speed\']), 1) == 1.5 or number_format((1 / $imgmeta[\'image_meta\'][\'shutter_speed\']), 1) == 1.6 or number_format((1 / $imgmeta[\'image_meta\'][\'shutter_speed\']), 1) == 2.5){ $pshutter = "1/" . number_format((1 / $imgmeta[\'image_meta\'][\'shutter_speed\']), 1, \'.\', \'\') . " second"; } else{ $pshutter = "1/" . number_format((1 / $imgmeta[\'image_meta\'][\'shutter_speed\']), 0, \'.\', \'\') . " second"; } } else{ $pshutter = $imgmeta[\'image_meta\'][\'shutter_speed\'] . " seconds"; } }
