我必须使用 php 将 excel 文件的数据上传到 MySQL 数据库。我找到了相关代码，但无法上传大文件。
谁能告诉我如何增加以下链接中提到的代码的最大文件大小限制:

最佳答案
您可以在 MySQL 中使用 LOAD DATA 命令:Read More
你必须在 mysql 语句中使用加载数据。这可以将您的大文件加载到数据库中。
mysqli_query($dblink, '
LOAD DATA LOCAL INFILE "'.$file.'"
INTO TABLE transactions
FIELDS TERMINATED by ","
OPTIONALLY ENCLOSED BY "\'"
LINES TERMINATED BY "\n"
');
