breaker of stuff, destroyer of things

Here’s a function to import csv data into mysql. It assumes the first line of your csv file contains the table column names.

also it uses custom functions make_db_connection and fixForDB either use the functions or write your own. get them here:

<?php
function processCsv($csvData,$seperator,$lineSeperator,$table){
global $findCurrentListing;
//process csv data
/*data should be in the following format
@line 1 = column names seperated by $seperator
all following lines should be data separated by $seperator with data groups separated by $lineSeperator
*/
//data shouldn’t have quotations around values, so lets remove them.
//also we’ll add slashes to data before inserting
//i’m using 0 as a subtitution for empty values. 0 will work for int,boolean, char values so thats why i choose it’
$nonEmpty=0;

$csvData=str_replace("\"","",$csvData);

$csvContent=explode($lineSeperator,$csvData);
//get rid of last item, it contains empty values
array_pop($csvContent);
$csvContent[0]=str_replace($seperator,’,',$csvContent[0]);

$csvColumns=explode(’,',$csvContent[0]);

$csvTotal=count($csvContent);
$csvColumnsNum=count($csvColumns);

for($loop=1;$loop<$csvTotal;$loop++){
set_time_limit(5);
$currData=explode($seperator,$csvContent[$loop]);
$fieldList=str_replace(",","`,`",$csvContent[0]);
$csv2DbInsertSQL="INSERT INTO $table ( `".trim(str_replace(" ","",$fieldList))."` ) VALUES (";
$csv2DbUpdateSQL="UPDATE $table SET ";
$csv2DbFindSQL="SELECT * FROM $table WHERE ";

for($buildLoop=0;$buildLoop<$csvColumnsNum;$buildLoop++){
