Are there any best practices for handling empty strings in PHP arrays?

When working with PHP arrays, it's important to handle empty strings properly to avoid unexpected behavior or errors. One common approach is to check for empty strings before performing any operations on them, such as filtering or processing. This can be done using functions like `array_filter()` or a simple loop with a conditional check.

// Example of handling empty strings in a PHP array
$array = ["apple", "", "banana", ""];

// Remove empty strings from the array
$array = array_filter($array, function($value) {
    return $value !== "";
});

// Output the updated array
print_r($array);
