Prevent array overwriting and instead create new array index

Question

I have a file and I need the save the content of the file in my MySQL database. Here is the code that I am using to parse the file:

$lines = file($tmp_filenam         


        

Answer 1

The data in the array is being overwritten because you are reassigning the value of $key each time it is encountered.

What you want to do is create a secondary array as the $key value and push nodes into that array this way you end up with your expected result.

[
    'NM1' => ['...', '...'],
    'PR1' => ['...', '...']
]

The code would be,

while (($row = fgetcsv($handle, 1000, ";", "\"", "\n")) !== FALSE) {
    $key = array_shift($row);
    // Notice the extra []
    $data[$key][] = $row;
}

Each key will now contain an array with a node for each row encountered.

Answer 2

try changing:

...
$data[$key] = $row;

to

...
$data[][$key] = $row;
