What steps can be taken to troubleshoot and resolve a PHP script error related to the 'array_filter()' function?

To troubleshoot and resolve a PHP script error related to the 'array_filter()' function, you can check for any syntax errors in the code, ensure that the callback function used in 'array_filter()' is correctly defined, and verify that the array being filtered is properly formatted. Additionally, you can use error handling techniques such as try-catch blocks to catch and handle any exceptions that may arise.

// Example PHP code snippet to fix array_filter() function error

// Sample array with some values
$array = [1, 2, 3, 4, 5];

// Define a callback function to filter out even numbers
function filterEven($value) {
    return $value % 2 == 0;
}

// Use array_filter() function with the defined callback function
$filteredArray = array_filter($array, 'filterEven');

// Output the filtered array
print_r($filteredArray);
