PHP - Creating an array from CSV and then echo the values

Question

I am attempting to parse CSV strings into a multi-dimensional array. I am using the following code to do this...

public function exportPartsAuthority($fileArray)
{       

    foreach ($fileArray as $filename => $fileContent) {
        $lines = explode("\n", $fileContent);
        $formatting = explode(",", $lines[0]);
        unset($lines[0]);
        $results = array();
        foreach ( $lines as $line ) {
           $parsedLine = str_getcsv( $line, ',' );
           $result = array();
           foreach ( $formatting as $index => $caption ) {
              if(isset($parsedLine[$index])) {
                 $result[$formatting[$index]] = trim($parsedLine[$index]);
              } else {
                 $result[$formatting[$index]] = '';
              }
           }
           $results[] = $result;
        }

        $var_str = var_export($results, true);
        $var = "<?php\n\n\$$values = $var_str;\n\n?>";
        file_put_contents('/home/apndev/public_html/output.txt', $var);

    }       
}

The end result is this:

$ = array (

  ),
);

When I attempt to echo $results['Vendor SKU'], or var_dump it.. the result is NULL even though I see a value set above. I also notice there is a syntax error at the top ('$ = array').

That being said, I'm ultimately just trying to get the values from the CSV because some of these values will be used to send order information to a third party vendor.

Can anyone point me in the right direction of how to fix my output so that I'll be able to echo the values correctly?

Thanks!

Answer 1

use the built in php function to parse your csv file rather than re-invent the wheel.

str_getcsv

http://php.net/manual/en/function.str-getcsv.php

There's a good example on the man page that essentially does what you want:

$header = NULL;
    $data = array();
    if (($handle = fopen($filename, 'r')) !== FALSE)
    {
        while (($row = fgetcsv($handle, 1000, $delimiter)) !== FALSE)
        {
            if(!$header)
                $header = $row;
            else
                $data[] = array_combine($header, $row);
        }
        fclose($handle);
    }
    print_r($data);

Answer 2

Simple, use the preset CSV reading method:

$fp = fopen('data.csv', 'r');

$rows = array();
while (($row = fgetcsv($fp)) !== false)
    $rows[] = $row;

fclose($fp);

$rows will then contain all data of data.csv as a two-dimensional array.

See fgetcsv() for more info.
