Are there any specific PHP functions or techniques that can help with pre-selecting checkboxes in PHP?

When pre-selecting checkboxes in PHP, you can use the `checked` attribute in the HTML input tag to mark a checkbox as selected. To do this dynamically in PHP, you can check if a specific value matches the one you want to pre-select, and then output the `checked` attribute accordingly. 

<?php
// Assume $selectedValue contains the value that should be pre-selected

// Check if the current checkbox value matches the selected value
function isChecked($value, $selectedValue) {
    if ($value == $selectedValue) {
        return 'checked';
    } else {
        return '';
    }
}

// Output the checkboxes with the pre-selected value
$checkboxValues = ['option1', 'option2', 'option3'];

foreach ($checkboxValues as $value) {
    echo '<input type="checkbox" name="checkbox[]" value="' . $value . '" ' . isChecked($value, $selectedValue) . '>';
}
?>
