使用PHP读取文本文件

Question

I have a text file, and it contains company names and prices. Like this:

first company name
2,2
second company name
2,7
third company name
1,9

The problem is that I can't read and show data properly. My code:

<?php
$content=file("test_data.txt");

foreach ($content as $data)
{
    $data = array(
    'company' => $content[0], 
    'price' => $content[1]
    );
    echo $data['company'];
    echo "<br>";
    echo $data['price'];
}
?>

What is wrong? I need also to send data to SQL database, but first I would have to clarify the code above.

Beacuse file function returns array of lines. And you loop lien by line, you should loop file by line-pairs. You can do it like this:

$lines = file("test_data.txt");
$data = array();
for($i = 0; $i < count($lines); $i += 2)
{
    $pair = array();
    $pair['company'] = $lines[$i];
    $pair['price'] = $lines[$i + 1];
    $data[] = $pair;
}

$data array should look similar to:

Array
(
    [0] => Array
        (
            [company] => first company name
            [price] => 2,2
        )

    [1] => Array
        (
            [company] => second company name
            [price] => 2,7
        )

    [2] => Array
        (
            [company] => third company name
            [price] => 1,9
        )

)
