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

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.
