Are there any PHP functions available for easily creating multidimensional arrays with variable keys?

When creating multidimensional arrays with variable keys in PHP, there isn't a built-in function specifically for this purpose. However, you can achieve this by using a combination of array functions such as array_combine, array_map, and array_fill_keys to dynamically create multidimensional arrays with variable keys. 

// Example code to create a multidimensional array with variable keys
$keys = ['key1', 'key2', 'key3'];
$values = ['value1', 'value2', 'value3'];

// Create an array with keys and values
$combined = array_combine($keys, $values);

// Map over the keys array and create a multidimensional array with variable keys
$multiArray = array_map(function($key) use ($combined) {
    return array_fill_keys([$key], $combined[$key]);
}, $keys);

print_r($multiArray);
