使用php将多个嵌套数组写入文件

Question

What I am trying to do is grab a Business Catalyst-generated CSV of my products. But it always includes a whole lot of stuff I don't need.

I have a script that uses fgetcsv(). The code is

<?php
$file_handle = fopen("ProductExport2.csv", "r");
    while (!feof($file_handle) ) {
$line_of_text = fgetcsv($file_handle, 1000000);
            $tableDisplay =  "<tr><td>" . $line_of_text[0] . "</td><td>" . $line_of_text[1] . "</td><td>" . $line_of_text[2] . "</td><td>" . $line_of_text[4] . "</td><td>" . $line_of_text[6] . "</td><td>" .  $line_of_text[49] . "</td></tr>";
            echo $tableDisplay;
    }
fclose($file_handle);
?>

All this does is display the data I want.

However, what I want to do now is write a new CSV file out of this. Using fwrite() only results in writing just the first entry of the data.

Any ideas?

Something like this.

<?php
    $file_handle = fopen("ProductExport2.csv", "r");
    $data = '';
    while (!feof($file_handle) ) {
        $line_of_text = fgetcsv($file_handle, 1000000);
        $data .=  $line_of_text[0] . "," . $line_of_text[1] . "," . $line_of_text[2] . "," . $line_of_text[4] . "," . $line_of_text[6] . "," .  $line_of_text[49] . "
";
    }
    fclose($file_handle);

    $new_file_handle = fopen("ProductExport2_reduced.csv", "w");
    fwrite($new_file_handle, $data);
?>
