Simple PHP upload image, delete image implementation code

Upload Image:

Copy the Code code as follows:

if (!empty ($_files["img" ["name"])) {//Extract the File field content name and determine
$path = "uppic/"; Upload path
if (!file_exists ($path))
{
Check if there is a folder, if not created, and give the highest permissions
mkdir ("$path", 0700);
}//end IF
Allow upload of file formats
$TP = Array ("Image/gif", "Image/pjpeg", "image/jpeg");
Check if the upload file is in a type that allows uploading
if (!in_array ($_files["img" ["type"], $TP))
{
echo "";
Exit
}//end IF
$filetype = $_files[' img ' [' type '];
if ($filetype = = ' Image/jpeg ') {
$type = '. jpg ';
}
if ($filetype = = ' Image/jpg ') {
$type = '. jpg ';
}
if ($filetype = = ' Image/pjpeg ') {
$type = '. jpg ';
}
if ($filetype = = ' Image/gif ') {
$type = '. gif ';
}
if ($_files["img" ["Name"])
{
$today =date ("Ymdhis"); Get time and assign a value to a variable
$file 2 = $path. $today. $type; The full path of the picture
$img = $today. $type; Picture name
$flag = 1;
}//end IF
if ($flag) $result =move_uploaded_file ($_files["img" ["Tmp_name"], $file 2);
Note that the first parameter passed to Move_uploaded_file here is a temporary file uploaded to the server
}//end IF
The value of $img is then written to the corresponding field in the database

To delete a picture:

Copy the Code code as follows:

Unlink ("uppic/". $img); Of course, the value of the variable is read from the database, PHP deleted pictures more concise than the ASP
