Question

我不明白为什么$ _FILES对象似乎存在并告诉我文件路径，但是当我查找文件它不存在时（注意在php.ini中没有设置upload_tmp_dir）所以它应该转到/ tmp目录，但是我没有在命令行看到它。）

我在控制台得到的回复：

Array
(
    [upload_file] => Array
        (
            [name] => Capture.PNG
            [type] => image/png
            [tmp_name] => /tmp/phplFIm0b
            [error] => 0
            [size] => 12612
        )

)
file upload failed

界面页面：

<?php
    include 'php/assets.php';
    $sel_str = "selected='selected'";
    $default_page_size = 100;
    $num_assets = count_assets();
    $num_pages = ceil($num_assets/$default_page_size);
