You can use LOAD DATA command in MySQL : Read More

you have to used load data in mysql statement. This can load your large file in database.

mysqli_query($dblink, '
    LOAD DATA LOCAL INFILE "'.$file.'"
        INTO TABLE transactions
        FIELDS TERMINATED by ","
        OPTIONALLY ENCLOSED BY "\'"
        LINES TERMINATED BY "\n"
');

Look at these values in your php.ini

upload_max_filesize = 10M post_max_size = 10M

回答3:

You need to set the value of upload_max_filesize and post_max_size in your php.ini :

; Maximum allowed size for uploaded files.
upload_max_filesize = 40M

; Must be greater than or equal to upload_max_filesize
post_max_size = 40M

I have to add that you have to restart the server

According to ASNAOUI Ayoub I made the following changes:

; Maximum allowed size for uploaded files.
upload_max_filesize = 40M

; Must be greater than or equal to upload_max_filesize
post_max_size = 40M

But Stil the Problem was same then I tried to change the

$max_filesize = 41943040

Now It perfectly works.....

Thanks Everyone for the help
