到網(wǎng)上搜索了一下前人的解決辦法，大多數(shù)都說修改php.ini中的upload_max_filesize，但修改了這個以后，還是提示這個問題；但phpmyadmin在提示這個問題的時候，右下角有一行英文提示，大致意思是說，解決這個問題，可以參考 phpmyadmin文檔；直接點(diǎn)擊這個鏈接，phpmyadmin自動查找到了以下說明：

[1.16] I cannot upload big dump files (memory, http or timeout problems).

Starting with version 2.7.0, the import engine has been re–written and these problems should not occur. If possible, upgrade your phpMyAdmin to the latest version to take advantage of the new import features.

The first things to check (or ask your host provider to check) are the values of upload_max_filesize, memory_limit and post_max_size in the php.ini configuration file. All of these three settings limit the maximum size of data that can be submitted and handled by PHP. One user also said that post_max_size and memory_limit need to be larger than upload_max_filesize.

以上文件大致說明的意思就是說，遇到導(dǎo)入過大文件時，首先檢查php.ini 配置文件中的以下三個地方，upload_max_filesize, memory_limit 和post_max_size，并且推薦修改的值要稍大于導(dǎo)入的巨大sql數(shù)據(jù)庫文件；依照這個提示，我修改了以上三個在php.ini中的值以后，重啟了php環(huán)境，再次導(dǎo)入時，雖然 phpmyadmin還是顯示導(dǎo)入最大限制：20,480 KB，但巨大的80M數(shù)據(jù)庫文件已經(jīng)被成功的導(dǎo)入了。
