php上传与删除图片的简单范例
1、上传图片的代码
复制代码 代码示例:
<?php
/**
php上传图片
link：/pic/p>
*/
if (!empty($_FILES["img"]["name"])) { /pic/p>
$path=”uppic/”; /pic/p>
if(!file_exists($path))
{
/pic/p>
mkdir(“$path”, 0700);
}/pic/p>
/pic/p>
$tp = array(“image/gif”,”image/pjpeg”,”image/jpeg”);
/pic/p>
if(!in_array($_FILES["img"]["type"],$tp))
{
echo “<script>alert(‘格式不对');history.go(-1);</script>”;
exit;
}/pic/p>
$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”); /pic/p>
$file2 = $path.$today.$type; /pic/p>
$img = $today.$type; /pic/p>
$flag=1;
}/pic/p>
if($flag) $result=move_uploaded_file($_FILES["img"]["tmp_name"],$file2);
/pic/p>
}/pic/p>
/pic/p>
?>
