Are there any specific functions or methods in PHP for merging variables?

PHP provides several functions for merging variables, such as array_merge(), array_merge_recursive(), and the "+" operator for arrays. These functions allow you to combine the values of two or more variables into a single variable. Depending on the specific requirements, you can choose the appropriate function to merge variables in PHP. 

// Using array_merge() to merge two arrays
$array1 = ['a', 'b', 'c'];
$array2 = ['d', 'e', 'f'];
$mergedArray = array_merge($array1, $array2);
print_r($mergedArray);

// Using the "+" operator to merge two arrays
$array3 = ['g', 'h', 'i'];
$array4 = ['j', 'k', 'l'];
$mergedArray2 = $array3 + $array4;
print_r($mergedArray2);
