以下是我的php脚本，可用于将视频文件（最大100MB）上传到我的服务器。 问题是，它可以毫无问题地上传一个mp4文件。但是，当我尝试上传其他文件时，会出现这些错误。 当我尝试上传2.57MB的“ T.J. Hooker（1982）-第1季OPENING.mp4”时，出现此错误：
array(1) { ["id_verification_video_file"]=> array(5) { ["name"]=>
string(41) "T.J. Hooker (1982) - Season 1 OPENING.mp4" ["type"]=>
string(0) "" ["tmp_name"]=> string(0) "" ["error"]=> int(1) ["size"]=>
int(0) } } Array ( [id_verification_video_file] => Array ( [name] => T.J.
Hooker (1982) - Season 1 OPENING.mp4 [type] => [tmp_name] => [error] => 1
[size] => 0 ) )
Q1。这个错误是什么意思？
当我尝试上传9.32MB的另一个文件“跆拳道与Jeet Kune Do.mp4”时，出现以下错误：
“ array（0）{}上传您的视频文件”。
Q2。为什么在尝试上传视频（mp4）文件时触发第17行？
第17行：

exit;
}

Q4。如何解决这些问题？我的意思是，如果脚本代码没有错误，并且能够上传一个mp4文件，那么它也应该能够上传其他mp4文件而不会显示错误。
答案 0 :(得分：0)
问题解决了。 .ini文件限制了文件大小。
