我似乎无法弄清楚如何为用户选择进行此循环暂停。它每次都会自动选择<?php
$name= 'filename';
$newname= '/images/'. $name;//. '.jpg'; // why wouldn't you preserve the correct extension? i.e. $file_ext
if(isset($_FILES['image'])){
$errors= array();
$file_name = $_FILES['image']['name'];
$file_size =$_FILES['image']['size'];
$file_tmp =$_FILES['image']['tmp_name'];
$file_type=$_FILES['image']['type'];
$file_ext=strtolower(end(explode('.',$_FILES['image']['name'])));
$expensions= array("jpeg","jpg","png");
if(in_array($file_ext,$expensions)=== false){
$errors[]="extension not allowed, please choose a JPEG or PNG file.";
}
/*if($file_size > 2097152){
$errors[]='File size must be excately 2 MB';
}*/
if(empty($errors)==true){
// // // use move_uploaded_file() instead // // //
//rename($file_tmp, $newname);
move_uploaded_file($file_tmp, "$newname.$file_ext");
echo "Success";
}else{
print_r($errors);
}
}
?>
<form action="" method="POST" enctype="multipart/form-data">
<input type="file" name="image" />
<input type="submit"/>
</form>
选项。我做错了什么？

您需要重定向“read abcde”以从tty读取。
read abcde < /dev/tty
由于while循环，stdin实际上来自重定向。
