PHP development image upload upload displays the same page
Many times when we upload pictures, they are on the same page as the displayed pictures. There is no need to jump to a separate page, so we will merge the two pages together in this section. The code is as follows]
Tip: You need to copy the code to run locally
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>圖片上傳</title>

<body>
<form id="form1" name="upload" enctype="multipart/form-data" method="post" action="">
