Thanks you very much. I was looking for a solution about to insert CSV file data which contains comma(,) in most of the columns values. I used Csvreader library but by using that I got data by exploding from comma(,) in column value. Now I got your function csv_to_array() and it solved my problem.

All my columns are double quotes ( "name something") and are nicely mapped. Except for the first one, which is correct in the CSV. Anyone got a clue?

[0] => "Contract Number"
[1] => Product Type
[2] => Internal Title

This happen because your csv file has special encoding, first you need to know what is it, than remove it. In my case was UTF-BOM, so the final version would be like this:

function csv_to_array($filename='', $delimiter=',', $encoding = NULL)
{
	if(!file_exists($filename) || !is_readable($filename))
		return FALSE;
	
	$header = NULL;
	$data = array();
	if (($handle = fopen($filename, 'r')) !== FALSE)
	{
		while (($row = fgetcsv($handle, 1000, $delimiter)) !== FALSE)
		{
			if(!$header)
				if($encoding) {
					$header = preg_replace('/' . $encoding . '/', '', $row); 
				}
				else
					$header = $row;
			else
				$data[] = array_combine($header, $row);
		}
		fclose($handle);
	}
	return $data;
}

Example:

print_r(csv_to_array('example.csv',,'[\x80-\xFF]')); // This will remove UTF-8 encoding
print_r(csv_to_array('example.csv', ',','[\x80-\xFF]'));

I have tried something like 3 different libraries for codeigniter with no success. Yours is the first one that works perfect without a touch.

THANK YOU!

Hi Thanks for the script :)

I will like to know how to make a foreach loop through the array? because I will like to echo the result out in a table

Sure, here's a simple, primitive example (code untested):

<?php
$data = csv_to_array('example.csv');

echo "<table>";
foreach ($data as $row) {
    echo "<tr>";
    foreach ($row as $column) {
        echo "<td>$column</td>";
    }
    echo "</tr>";
}
echo "</table>";

Hi agaín :)

In the csv file there are two columns ,name and numbers, I will like do use the PHP max() Function to get the highest value in an array of the cummum number?

How can i do that?

There's many ways you can achieve that, I'd suggest reading through this tutorial, or picking up a good book on the PHP language. With a little time, it's easy to pick up the basics.

Thanks I do know some basic PHP and i have made this task, justmore simple, without the csv file, but this is a little more advanced for me :)

<style> table { font-family: arial, sans-serif; border-collapse: collapse; width: 100%; }

td, th {
border: 1px solid #dddddd;
text-align: left;
padding: 8px;
}
</style>

As of PHP 8.0, you can set the length to 0 (or null, or omit it entirely) for the fgetcsv() function if you don't want to limit the maximum line length.
