array_merge() Function<\/h2>\n\n\n\n

 <\/strong>The array_merge()<\/strong> function is used to merge two or more arrays into a single array. This function is used to merge the elements or values of two or more arrays together into a single array. it always work with index array and associative array<\/p>\n\n\n\n

array_combine() Function<\/h2>\n\n\n\n
The array_combine() function is used to combine two arrays and create a new array by using one array for keys and another array for values, all elements of one array will be the keys of new array and all elements of the second array will be the values of this new array.<\/p>\n\n\n\n
