How do I split a large MySQL backup file into multiple files?

You can use mysql_export_explode https://github.com/barinascode/mysql-export-explode

db = 'dataBaseName'; # -- Set your database name
$export->connect('host','user','password'); # -- Connecting to database
$export->rows = array('Id','firstName','Telephone','Address'); # -- Set which fields you want to export
$export->exportTable('myTableName',15); # -- Table name and in few fractions you want to split the table

At the end of the SQL files are created in the directory where the script is executed in the following format
---------------------------------------
myTableName_0.sql
myTableName_1.sql
myTableName_2.sql
