我有這段代碼來上傳jpg文件。我需要重命名某人上傳到newtexture.jpg的文件。如何在php中更改上傳文件的名稱?
<?php
$demo_mode = false;
$upload_dir = 'uploads/';
$allowed_ext = array('jpg','jpeg');
if(strtolower($_SERVER['REQUEST_METHOD']) != 'post'){
exit_status('Error! Wrong HTTP method!');
}
if(array_key_exists('pic',$_FILES) && $_FILES['pic']['error'] == 0){
$pic = $_FILES['pic'];
if(!in_array(get_extension($pic['name']),$allowed_ext)){
exit_status('Only '.implode(',',$allowed_ext).' files are allowed!');
}
if($demo_mode){
$line = implode(' ', array(date('r'), $_SERVER['REMOTE_ADDR'], $pic['size'], $pic['name']));
file_put_contents('log.txt', $line.PHP_EOL, FILE_APPEND);
exit_status('Uploads are ignored in demo mode.');
}
if(move_uploaded_file($pic['tmp_name'], $upload_dir.$pic['name'])){
exit_status('File was uploaded successfuly!');
}
}
exit_status('Something went wrong with your upload!');
function exit_status($str){
echo json_encode(array('status'=>$str));
exit;
}
function get_extension($file_name){
$ext = explode('.', $file_name);
$ext = array_pop($ext);
return strtolower($ext);
}
?>
PS。它說它大部分是編碼的,以便添加更多細節?還有什麼...我是學生,我需要它爲我的凱普斯通項目,這是一個緊急情況...
