How can PHP developers effectively use if-conditions to manipulate array data?

PHP developers can effectively use if-conditions to manipulate array data by checking for specific conditions within the array and performing actions based on those conditions. For example, developers can use if-conditions to filter out unwanted elements from an array, modify specific elements that meet certain criteria, or create new arrays based on specific conditions. 

// Example: Filtering out odd numbers from an array
$numbers = [1, 2, 3, 4, 5, 6, 7, 8, 9];
$filteredNumbers = [];

foreach ($numbers as $number) {
    if ($number % 2 == 0) {
        $filteredNumbers[] = $number;
    }
}

print_r($filteredNumbers);
