Question

i have a .sql file which contains the exported code from some database

   # Dump File
    # Database is ported from MS Access
    CREATE DATABASE IF NOT EXISTS `movedb`;
    # Table structure for table 'test_prefixSwitchboard Items'
    DROP TABLE IF EXISTS `test_prefixSwitchboard Items`;
    CREATE TABLE `tbl` (
      `x` INTEGER NOT NULL, 
      `y` INTEGER NOT NULL DEFAULT 0, 
      `z` VARCHAR(255)
    ) ENGINE=innodb DEFAULT CHARSET=utf8;
    SET autocommit=1;
    #
    # Dumping data for table 'Switchboard Items'
    #
    INSERT INTO `tbl` ( `x`, `y`, `z`) VALUES ( '111' , '111' ,'111');
    INSERT INTO `tbl` ( `x`, `y`, `z`) VALUES ( '222' , '2222' ,'222');
    INSERT INTO `tbl` ( `x`, `y`, `z`) VALUES ( '333' , '333' ,'333');

i want to put it’s values into my database , my column names are diferent from .sql file column names so i need to only extract the values i.e

'111' , '111' ,'111'
'222' , '2222' ,'222'
'333' , '333' ,'333'

and there might be some other tables in that file so its important to get this table only .

i usually don’t ask question without providing any code of my own , but i suck at regex stuff and this seems very complected at least to me.

i have to add , someone is going to uupload this file every couple of day . and i want to add some values to current values before inserting them on my database so i’m more comfortable to use regex

You can match the VALUES ( portion, then capture the text from then on until you hit ); and the end of the string, like this:

preg_match_all( '/VALUES\s+\(\s+(.*?)(?=\);\s*$)/', $file, $matches);

foreach( $matches[1] as $match) {
    echo $match;
}

This will print:

'111' , '111' ,'111' 
'222' , '2222' ,'222' 
'333' , '333' ,'333'

Edit: For table names, you would add the table name to the regex, then churn through the column names since you don’t care about capturing them like this:

preg_match_all( '/`tbl`.*?VALUES\s+\(\s+(.*?)(?=\);\s*$)/m', $file, $matches);

Where you can change tbl to anything you need.
