PHP破碎/爆炸文本

Question

I have a one input that is used for a "Name, Surname and Family name". But I want if user enter more than 3 names, all after 3(4,5,6...) to be like family. But if you submit 2 names the Family name must be "0".

Here is my code:

<form method="POST" action="getNames.php">
    Names: <input type="text" name="names" />
    <input type="submit" name="submit" />
</form>

<?php

$names = $_POST['names'];

// some action here to get names

$firstName = ""; // Get first name
$surName = ""; // Get Sur name
$familyName = ""; // Get family name

?>

I will be very glad if someone help me. Thanks!

Answer 1

This code will output an array of familly, if an input is missing, it will be replaced with a 0.

PHP

<?php
$_POST['names'] = 'sofiene, totose, tata, titi';
$names = explode(',', $_POST['names']);
$familly = [];

for ($i = 0; $i < count($names); $i+=3) {
    $familly[$i] = [
        'firstName' => (isset($names[$i])) ? $names[$i] : 0,
        'surName' => (isset($names[$i + 1])) ? $names[$i + 1] : 0,
        'familyName' => (isset($names[$i + 2])) ? $names[$i + 2] : 0
    ];
}
var_dump($familly);
?>
