PHP Code

  select_db ($database); $work _group = Check_input ($_post[' work_group ')); $name = Check_input ($_post[' name '); $tel = Check_input ($_post[' Tel ')), $id _card = check_input ($_post[' Id_card '); $work _name = Check_input ($_post[' work_name ')) ; $place = Check_input ($_post[' place '); $work 1 = check_input ($_post[' Work1 ']);d ate_default_timezone_set (' PRC '); $ Date = Date ("y-m-d h:i:s"), $quality = N, $quality 2 = $quality, $quality _png = 9; 2_png = 7;if (isset ($_files[' Work1 ']) &am p;& $_files[' work1 ' [' Error ']==0] {$size = getimagesize ($_files[' work1 ' [' tmp_name ']); $original = $_files[' Work1 ' [' tmp_name ']; $type = $_files[' work1 ' [' type '];//echo $type; $target _name = Date (' Ymdhis ').

Some questions need to be explained below:

The quality of the image generated by the JPEG image is a range from 0 (lowest quality, smallest file size) to 100 (highest quality, maximum file size). The imagepng generates an image with a mass range from 0 to 9, and the function does not work if the parameter is passed outside this range.

Determine the type of upload file, $type = $_files[' work1 ' [' type '];.

You can use these functions to create pictures of various formats: Imagecreatefromjpeg (), Imagecreatefrompng (), Imagecreatefromgif ().
