} // closing for if (tableName == "tbl_driver") || (tableName == "tbl_vehicle")
and how i execute the sh with php
<?php
$output = shell_exec('mysql2sqlite.sh -h host -u username -pmypasswrord db_shuttlebus | sqlite3 database.sqlite');
echo "<pre>$output</pre>";
?>
mySQL database is having 3 table,
1)tbl_driver
2)tbl_vehicle
3)tbl_ticket
but, when copy to sqlite database i just want the 2 tables created, that is tbl_driver and tbl_vehicle.
so i have added in .sh with if (tableName == "tbl_driver") || (tableName == "tbl_vehicle"){ if the table name is this two table name only create the table, but still not working ? why?
