Okay, I’m having some serious issues here. I’m new to this site, and new to dealing with importing CSV data via PHP, but I’m not new to programming.
Currently, I’m working on building a Customer Relationship Manager. I need to create a script to import a file that will populate the database with leads. The main issue here is that the Lead data consists of Companies and Employees of said Company. Also, a few other tables are split off, such as billing information, from the main tables.
I have a working script that will allow users to map the imported data to specific rows and columns.
function mapData($file) {
// Open the Text File
$fd = fopen($file, "r");
// Return FALSE if file not found
if(!$fd) {
return FALSE;
}
// Get the First Two Lines
$first = 0;
$data = array();
while(!feof($fd)) {
if($first == 0) {
$cols = fgetcsv($fd, 4096);
$data['cols'] = array();
if(is_array($cols) && count($cols)) {
foreach($cols as $col) {
if(!$col) {
continue;
}
$data['cols'][] = $col;
}
}
if(empty($data['cols'])) {
return array();
}
$first++;
continue;
}
else {
$data['first'] = fgetcsv($fd, 4096);
break;
}
}
fclose($fd);
// Return Data
return $data;
}
The above script only activates after CodeIgniter moves the file to a working directory. I already know what the file name is by this point. The file goes in and returns the list of columns and the first row. Any empty columns are ignored.
After this, process passes to a mapping script. Once mapping is done and “Import” is pressed, this piece of code loads.
function importLeads($file, $map) {
// Open the Text File
if(!file_exists($file)) {
return false;
}
error_reporting(E_ALL);
set_time_limit(240);
ini_set("memory_limit", "512M");
$fd = fopen($file, "r");
// Return FALSE if file not found
if(!$fd) {
return FALSE;
}
// Traverse Each Line of the File
$true = false;
$first = 0;
while(!feof($fd)) {
if($first == 0) {
$cols = fgetcsv($fd);
$first++;
continue;
}
// Get the columns of each line
$row = fgetcsv($fd);
// Traverse columns

Now, as far as I can see, the script works perfectly fine. There’s nothing wrong with the actual code itself. The problem is that after around 400-500 rows, the script just stops. I don’t receive an error, but no further code is processed.
I know this because I have code after this that is supposed to return a redirect page through AJAX. Nothing after my loop in the importLeads function ever loads, though.
I’m not sure how to make this script more efficient… I’m positive it is timing out, but I don’t know how to make it run more efficiently. I NEED this script to process all the information above separately. I have a variety of separate tables that all link together, and this import script has to set everything up in different ways.
I’ve talked with my client about this project. This script works when I drop it to around 400 rows. He has some a lot of these CSV files that are around 75,000 rows. The one I am importing is a smaller one, only about 1,200 rows.
I’ve tried looking into alternate methods, such as MySQL’s import script, but I can’t do that because this script must import data into separate tables, and it must check for existing data first. I’m also supposed to have all empty fields update with imported information, but that will make this even worse.
If anyone knows of a more efficient method it would be much appreciated. I tried to be as detailed as I could. Of note, I will mention that I’m using CodeIgniter, but if there’s a more efficient way that doesn’t use CodeIgniter I’ll take it (I can still put it into a CI model, though).
I have written PHP scripts to bulk-load the data published by Stack Overflow data dump. I import millions of rows and it doesn’t take that long.
Here are some tips:
Don’t rely on autocommit. The overhead of starting and committing a transaction for every row is enormous. Use explicit transactions, and commit after every 1000 rows (or more).
Use prepared statements. Since you are basically doing the same inserts thousands of times, you can prepare each insert before you start looping, and then execute during the loop, passing values as parameters. I don’t know how to do this with CodeIgniter’s database library, you’ll have to figure it out.
Tune MySQL for import. Increase cache buffers and so on. See Speed of INSERT Statements for more information.
Use LOAD DATA INFILE. If possible. It’s literally 20x faster than using INSERT to load data row by row. I understand if you can’t because you need to get the last insert id and so on. But in most cases, even if you read the CSV file, rearrange it and write it out to multiple temp CSV files, the data load is still faster than using INSERT.
Do it offline. Don’t run long-running tasks during a web request. The time limit of a PHP request will terminate the job, if not today then next Tuesday when the job is 10% longer. Instead, make the web request queue the job, and then return control to the user. You should run the data import as a server process, and periodically allow the user to glimpse the rate of progress. For instance, a cheap way to do this is for your import script to output “.” to a temp file, and then the user can request to view the temp file and keep reloading in their browser. If you want to get fancy, do something with Ajax.
