Read from large array

Question

I want to ask how can I read from my associative array:

Array
(
    [0] => Array
        (
            [imie;nazwisko;telefon] => 3;[email protected];123456789
        )

    [1] => Array
        (
            [imie;nazwisko;telefon] => 6;[email protected];123456789
        )

    [2] => Array
        (
            [imie;nazwisko;telefon] => 7;[email protected];123456789
        )

    [3] => Array
        (
            [imie;nazwisko;telefon] => 16;[email protected];123456789
        )

    [4] => Array
        (
            [imie;nazwisko;telefon] => 17;[email protected];123456789
        )

    [5] => Array
        (
            [imie;nazwisko;telefon] => 19;[email protected];123456789
        )

    [6] => Array
        (
            [imie;nazwisko;telefon] => 32;[email protected];123456789
        )

    [7] => Array
        (
            [imie;nazwisko;telefon] => 39;[email protected];123456789
        )

    [8] => Array
        (
            [imie;nazwisko;telefon] => 50;[email protected];123456789
        )

    [9] => Array
        (
            [imie;nazwisko;telefon] => 52;[email protected];123456789
        )

    [10] => Array
        (
            [imie;nazwisko;telefon] => 54;[email protected];123456789
        )

    [11] => Array
        (
            [imie;nazwisko;telefon] => 720;[email protected];123456789
        )

    [12] => Array
        (
            [imie;nazwisko;telefon] => 54;[email protected];123456789
        )

)

I create this array with this code:

$csv = array_map("str_getcsv", file($path,FILE_SKIP_EMPTY_LINES));
$keys = array_shift($csv);
foreach ($csv as $i=>$row) {
$csv[$i] = array_combine($keys, $row);
}
echo '<pre>';
print_r($csv);
echo '</pre>';

How can I loop through all items and then get from each item: imie,nazwisko and telefon?

You had some real email addresses and telephone numbers here. I've submitted an order to remove them from the revision history, but they've been scraped on other sites. You probably want to contact these people and make sure they know that their information has been leaked, so they can take appropriate steps. — Cody Gray

Use a few loops and the explode function:

foreach($array as $arrIdx => $subArr){
   foreach($subArr as $keys => $values) {
         $key = explode(";", $keys);
         $value = explode(";", $values);

         for($i=0; $i <= 2; $i++){
            echo $key[$i]." : ".$value[$i];
         }
   }
}

That's great! Is there any possibility to check the number of columns instead of using static value? for($i=0; $i <= 2; $i++){

@forexknight use $i < count($key)

@forexknight Yes sure, change loop to for($i=0; $i <= count($value)-1; $i++){ }

I would change the code of yours for this one:

$csv = array_map("str_getcsv", file($path,FILE_SKIP_EMPTY_LINES));
$keys = explode(";", array_shift($csv));
foreach ($csv as $i=>$row) {
    $csv[$i] = array();
    foreach (explode(";", $row) as $j => $element) {
         $csv[$i][$keys[$j]] = $element;
    }
}

This way you obtain the correct associative array.
