Array in While Loop PHP

Question

I have a while loop that loops through line of text

while ($line_of_text = fgetcsv($file_processing, 4096)) {

In this while loop I assign variables to different parts of the array

   IF($i > 0)
   {
    echo "</br>";
    $account_type_id = $line_of_text[0];
    echo "Account Type ID: " . $account_type_id. "<br>";

    $account_number = $line_of_text[1];
    echo "account_number = " . $account_number . "<br>";

This while loop loops through many lines. I am trying to find a way to say that

IF $account_type_id == 99 then add $account_number to an array. Then outside of the while loop print out the whole array of $account_numbers where $account_type_id == 99.

I have tried using print_r but it will only display the last array...

if($account_type_id == 99){ $account_numbers[] = $account_numbers; }? — gen_Eric

To add the element to an array, you can use array_push.

First you need to create the array (before the while loop):

$my_array = array();

Then, in the while loop, do this:

if ($account_type_id == 99) {
    array_push($my_array, $account_number);
}

Then to display the array, either use print_ror var_dump. To make the array easier to read, you can also do this:

echo "<pre>".print_r($my_array, 1)."</pre>";

$my_array = new array(); is not PHP syntax.

Simple mistake to change. Don't see the need to downvote, but hey ho!

you can refer to my first comment.

But the rest was correct. As I said, a simple mistake was made and it was now been rectified. My last comment was just to check I had not made any other mistakes ;)

Rocket H had the answer in the comment he posted

inside of your loop

if($account_type_id == 99){
    $account_numbers[] = $account_number;
   }

After loop

print_r($account_numbers);
