It returns the resulting array. If the input arrays have the same string keys, then the values for these keys are merged together into an array, and this is done recursively, so that if one of the values is an array itself, the function will merge it with a corresponding entry in another array too, php combine arrays. If, however, the arrays have the php combine arrays numeric key, the later value will not overwrite the original value, but will be appended.

Merges the elements of one or more arrays together so that the values of one are appended to the end of the previous one. It returns the resulting array. If the input arrays have the same string keys, then the later value for that key will overwrite the previous one. If, however, the arrays contain numeric keys, the later value will not overwrite the original value, but will be appended. Values in the input arrays with numeric keys will be renumbered with incrementing keys starting from zero in the result array. Returns the resulting array. If called without any arguments, returns an empty array.
