Simple PHP upload image, delete image implementation code

Upload image:

Copy code The code is as follows:

if (!empty($_FILES["img"]["name"])) { //Extract the file domain content name and determine
$path =”uppic/”; //Upload path
if(!file_exists($path))
{
//Check whether the folder exists, if not, create it and give the highest permissions
mkdir(“$path”, 0700 );
}//END IF
//File formats allowed to be uploaded
$tp = array("image/gif","image/pjpeg","image/jpeg");
//Check whether the uploaded file is allowed Upload type
if(!in_array($_FILES["img"]["type"],$tp))
{
echo “<script>alert('wrong format');history.go(-1) ;</script>”;
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 the time and assign it to the variable
$file2 = $path.$today.$type; //The full path of the image
$img = $today.$type; //Picture name
$flag=1;
}//END IF
if($flag) $result=move_uploaded_file($_FILES["img"]["tmp_name"],$file2);
//Pay special attention here The first parameter passed to move_uploaded_file is the temporary file uploaded to the server
}//END IF
//Then write the value of $img to the corresponding field in the database

Copy the code The code is as follows:

unlink(“uppic/”.$img); //Of course, the value of the variable is read from the database. PHP is much simpler to delete pictures than ASP
