I have a base table in a MySQL database that has 200,000 records.
The structure of this table is as follows:
CREATE TABLE `npanxxmaster` (
`npanxx` varchar(6) NOT NULL DEFAULT '',
`npa` varchar(3) DEFAULT NULL,
`ocn_lata` varchar(7) DEFAULT NULL,
`lata` varchar(3) DEFAULT NULL,
`st` varchar(2) DEFAULT NULL,
`canada` varchar(10) DEFAULT NULL,
`ext` varchar(10) DEFAULT NULL,
`er` double DEFAULT NULL,
`ra` double DEFAULT NULL,
`un` double DEFAULT NULL
)
I'm storing this table into an array with the key being the npanxx value.
I have a flat csv file that has the following structure:
npanxx(or npa only), ER, RA , UN
For a little more information npanxx is a 6 digit number and npa will always be a 3 digit number (from the npanxx).
Now this flat file, in the first column can have either npanxx (6 digits) or npa (3 digits).
What I need to do is read in each line of the csv file (which I can already do) and I store that into an array with the following code:
if (($handle = fopen($fileName, "r")) !== FALSE) {
while (($row = fgetcsv($handle, 1000, ",")) !== FALSE){
Now here comes the tricky part. What I need to do is go through each of the $row (lines in the csv file) and find a match in the original $npanxxmaster array that I made from the MySQL table. The problem I have is the flat file can contain in its first column either npanxx or npa. And what I need to do with those are match them with the matching npanxx or npa in the $npanxxmaster array with any $row that has an npanxx taking precident over one that only has an npa.
For example:
If given in the flat csv file the following $rows:
201,.002,.002,.002
201200,.001,.001,.001
All entries in the $npanxxmaster array with an npa of 201 would get the .002,.002,.002 OTHER THAN 201200 which would get .001,.001,.001
I have no been able to achieve this at all. I can provide more code of what I have tried or more explanation if needed because i'm assuming I butchered that explanation.
Thank you all in advance for all the help!
