What is diffrence between array_merge and array_combine

Question

Accepted Answer

array_merge merges two or more arrays into a single array, while array_combine creates an array by using one array for keys and another for values.

array_merge merges arrays together, preserving numeric keys and reindexing the resulting array, while array_combine creates an array by using one array for keys and another for values
array_merge can merge multiple arrays together, while array_combine requires two arrays of equal length
Example: array_merge([1, 2], [3, 4]) returns [1, 2, 3, 4], while array_combine(['a', 'b'], [1, 2]) returns ['a' => 1, 'b' => 2]
