Question

Put simply, I need to take the first column of an array and turn that into a named array, multiple times over within a single 2d array.

$arr[0][0] = “Name”
$arr[1][0] = “Version”
…etc, allowing me to then access them as:
$arr[“Name”][1] = “Bob”
$arr[“Version”][1] = “1.00”

How do you assign variable names to an index? If that makes sense. I don’t know the proper terms for this kind of thing… Or at least not how to use them.

Anyway, the actual array looks like this:

Name,Version,Compact,OpenGFx
Element1,1.0,0,0,1
Element2,1.23,0,0,1
ElementN,1.0,0,0,1

I started writing identifiers to do the same thing ($name=0, $version=1, etc.) but there are 165 columns! So automation would be much easier, and I am interested in learning new things as always!

Answer 1

If I understand it right, you don’t want to be writing out all of the headings right? Maybe you could do something similar to this code:

I’ve just assumed the format of the input array, you might need to change it around a bit:

$input = array(
    array('name', 'version', 'compact'), // and so on
    array('element1', 1.0, 0),
    array('element2', 1.3, 1) // and so on
);

$headings = array_shift($input);

$output = array();
foreach ($input as $row) {
    $newrow = array();
    foreach ($headings as $index => $name) {
        $newrow[$name] = $row[$index];
    }
    $output[] = $newrow;
}

var_dump($output);
