Question

我有这个脚本：

 if(($_POST['number2'] && !$_POST['button_add']) || ($_POST['number2'] && !$_POST['button_add_gal'])) { $num=$_POST['number2'];
            for($p=0; $p<$num; $p++) {
            if ($_POST['page']=='news') {
                        $dir = '../images/news/'; // Директорията в която ще се записват файловете
                        }
                        if ($_POST['page']=='gallery') {
                        $dir = '../images/gallery/'; // Директорията в която ще се записват файловете
                        }
                        $name[$p]='gal_'.$_FILES['file']['name'][$p];
                        move_uploaded_file($_FILES['file']['tmp_name'][$p], $dir.$name[$p]);
            $filename[$p] = $name[$p];



                        if ($_POST['page']=='news') {
                        createThumb('../images'.DIRECTORY_SEPARATOR.'news'.DIRECTORY_SEPARATOR.$filename[$p]);

                echo '<img src="../images/news/thumb_'.$filename[$p].'" width="50" height="50" border="0" style="margin-left:10px;">';
                        }
                        if ($_POST['page']=='gallery') {
                          createThumb('../images'.DIRECTORY_SEPARATOR.'gallery'.DIRECTORY_SEPARATOR.$filename[$p]);

                echo '<img src="../images/gallery/thumb_'.$filename[$p].'" width="50" height="50" border="0" style="margin-left:10px;">';

                 if($_POST['page']=='gallery'){
            resizeImage('../images'.DIRECTORY_SEPARATOR.'gallery'.DIRECTORY_SEPARATOR.$filename[$p]);   }
                        if ($_POST['page']=='news'){
                           resizeImage('../images'.DIRECTORY_SEPARATOR.'news'.DIRECTORY_SEPARATOR.$filename[$p]);
                        }
                        }
 } }  

 function createThumb($source, $thumb_width=150)
        {
     $fl = dirname($source);
     $new_name = 'thumb_'.basename($source);
     $img = imagecreatefromjpeg($source);
     $width = imagesx($img);
     $height = imagesy($img);
     $new_width = $thumb_width;
     $new_heght = floor($height * ($thumb_width / $width));
     $tmp_img = imagecreatetruecolor( $new_width, $new_heght );
     imagecopyresampled($tmp_img, $img, 0, 0, 0, 0, $new_width, $new_heght, $width, $height);
      imagejpeg($tmp_img, $fl.DIRECTORY_SEPARATOR.$new_name);
        }

         function resizeImage($source, $thumb_width=700)
        {
     $fl = dirname($source);
     $new_name = basename($source);
     $img = imagecreatefromjpeg($source);
     $width = imagesx($img);
     $height = imagesy($img);
     $new_width = $thumb_width;
     $new_heght = floor($height * ($thumb_width / $width));
     $tmp_img = imagecreatetruecolor( $new_width, $new_heght );
     imagecopyresampled($tmp_img, $img, 0, 0, 0, 0, $new_width, $new_heght, $width, $height);
      imagejpeg($tmp_img, $fl.DIRECTORY_SEPARATOR.$new_name);
        }

它适用于小图片，但如果我使用更大的图片，它只适用于2个文件。如果我附加3个或更多文件，则上传它们，当页面刷新时，期望看到上传的图片，页面上没有任何内容。它返回默认状态。甚至没有显示错误消息。我将php5.ini upload_max_filesize重新配置为100M但仍然没有。我使用php5文件扩展名，并且使用CGI模式将safe_mode关闭到php5并且gd2处于活动状态。可能是什么问题？

我想知道你的脚本是否超时？添加ini_set（“max_execution_time”，500）;或者在脚本顶部的东西，看看是否有帮助
