How can implementing a group break based on continent and country names improve the display of data in PHP?
To improve the display of data in PHP by implementing a group break based on continent and country names, we can create an associative array where the keys are the continent names and the values are arrays of country names. We can then loop through the data and use conditional statements to check the continent of each country and display a group break when the continent changes.
$data = [
'Asia' => ['China', 'Japan', 'India'],
'Europe' => ['France', 'Germany', 'Italy'],
'North America' => ['USA', 'Canada', 'Mexico']
];
$prevContinent = null;
foreach ($data as $continent => $countries) {
if ($continent != $prevContinent) {
echo "<h2>{$continent}</h2>";
}
foreach ($countries as $country) {
echo "<p>{$country}</p>";
}
$prevContinent = $continent;
}
