How can PHP be used to dynamically determine and display a specific value and its surrounding data in a two-dimensional array?

To dynamically determine and display a specific value and its surrounding data in a two-dimensional array, you can use nested loops to iterate through the array and check each element for the desired value. Once the value is found, you can display it along with its surrounding data by accessing the neighboring elements in the array. 

<?php
// Sample two-dimensional array
$array = array(
    array(1, 2, 3),
    array(4, 5, 6),
    array(7, 8, 9)
);

$desiredValue = 5; // Value to search for

foreach ($array as $rowKey => $row) {
    foreach ($row as $colKey => $value) {
        if ($value == $desiredValue) {
            echo "Value: $value\n";
            echo "Top: " . ($array[$rowKey-1][$colKey] ?? 'N/A') . "\n";
            echo "Bottom: " . ($array[$rowKey+1][$colKey] ?? 'N/A') . "\n";
            echo "Left: " . ($array[$rowKey][$colKey-1] ?? 'N/A') . "\n";
            echo "Right: " . ($array[$rowKey][$colKey+1] ?? 'N/A') . "\n";
        }
    }
}
?>
