How can a function be written in PHP to handle the creation of HTML select boxes from arrays or database results with preselected values?
When creating HTML select boxes from arrays or database results in PHP, it can be useful to have a function that generates the select options with preselected values. This can be achieved by looping through the array or database results to generate the options, while checking if the current value matches the preselected value. The function can then output the HTML select box with the appropriate options selected.
function createSelectWithOptions($options, $selectedValue) {
$select = '<select>';
foreach ($options as $option) {
$select .= '<option value="' . $option['value'] . '"';
if ($option['value'] == $selectedValue) {
$select .= ' selected';
}
$select .= '>' . $option['label'] . '</option>';
}
$select .= '</select>';
return $select;
}
// Example usage
$options = [
['value' => '1', 'label' => 'Option 1'],
['value' => '2', 'label' => 'Option 2'],
['value' => '3', 'label' => 'Option 3']
];
$selectedValue = '2';
echo createSelectWithOptions($options, $selectedValue);
