First go to the source code, you can copy it to your own computer and run it ~
Copy the code The code is as follows:
Multiple file upload< /title> <br></head> <br><body> <br><form accept="" method="post" enctype="multipart/form-data"> <br><input type="file" name="img[]" /><br /> <br><input type="file" name="img[]" /><br /> <br><input type="file" name="img[]" /><br /> <br><input type="file" name="img[]" /><br / > <br><input type="file" name="img[]" /><br /> <br><input type="file" name="img[]" /> <br /> <br><input type="submit" name="s" /><br /> <br></form> <br><?php <BR>/ /Upload file information<BR>$img = $_FILES['img']; <BR>if ($img) <BR>{ <BR>//File storage directory, same level as this php file<BR>$dir = dirname(__file__); <BR>$i = 0; <BR>foreach ($img['tmp_name'] as $value) <BR>{ <BR>$filename = $img['name'][$i ]; <BR>if ($value) <BR>{ <BR>$savepath="$dir\$filename"; <BR>$state = move_uploaded_file($value, $savepath); <BR>//If uploaded Success, preview<BR>if($state) <BR>{ <BR>echo "<img src='$filename' alt='$filename' /> "; <br>} <br>} <br>$i++; <br>} <br>} <br>?> <br></body> <br></html> <br>
</div> <br>move_uploaded_file() function<br> The move_uploaded_file() function moves the uploaded file to a new location. Returns true if successful, false otherwise. <br>Usage: move_uploaded_file(file,newloc) <br>Parameter file, required. Specifies the files to be moved. <br>Parameter newloc, required. Specifies the new location of the file. <br>This function checks and ensures that the file specified by file is a legal upload file (that is, uploaded through PHP's HTTP POST upload mechanism). If the file is legal, it is moved to the file specified by newloc. <br>If file is not a legal uploaded file, no operation will occur and move_uploaded_file() will return false. <br>If file is a valid uploaded file but cannot be moved for some reason, no action will occur and move_uploaded_file() will return false and a warning will be issued. <br>This check is particularly important if the uploaded file may cause its content to be displayed to the user or other users of this system. <br>Note: This function is only used for files uploaded via HTTP POST. <br>Note: If the target file already exists, it will be overwritten.
