mysql terminated_LINES TERMINATED BY和FIELDS TERMINATED BY的多种可能性 - MySQL

I'm trying to create a feature in my Content Management System in which users can upload a CSV file which is then parsed and the data is put in a MySQL database. To do this I use a file input and this SQL query.

$sql = "LOAD DATA LOCAL INFILE '".$_FILES["file"]["tmp_name"]."'

INTO TABLE persons

FIELDS TERMINATED BY ';'

LINES TERMINATED BY '\r'

(id, name, email, contacts)";

This works perfectly for a .csv file I created on my computer, but not al CSV files have fields that are terminated by a semicolon and have lines that are terminated with a \r. Now I want this query to work for all .csv files. Otherwise this feature won't work well enough to be implemented in my CMS. Is there any way I can make this work for .csv files which have other field and line endings? (e.g \n, \r\n, ,)

Try LINES TERMINATED BY '\r\n'

This will work for files ending lines with '\r\n', but also with '\r' and '\n'. From the MySQL docs:

The FIELDS TERMINATED BY, LINES STARTING BY, and LINES TERMINATED BY

values can be more than one character. For example, to write lines

that are terminated by carriage return/linefeed pairs, or to read a

file containing such lines, specify a LINES TERMINATED BY '\r\n'

clause.

[EDITED]

You also need to add \r\n to the clause FIELDS TERMINATED BY in order to tell the parser not to include the end-of-lines symbols in the last field of the first line. So

FIELDS TERMINATED BY ';, \t\r\n'

will work in most cases.
