#Php array merge how to#

This function is used to merge the elements or values of two or more arrays together into a single array. // ]Īll of that being said, you could also use the + operator to merge multidimensional arrays, but it will work slightly different compared to array_merge. The arraymerge () is a builtin function in PHP and is used to merge two or more arrays into a single array. That is 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. So if you want to merge multidimensional arrays, you can simply use array_merge, it can handle multiple levels of arrays just fine: $first = [ The arraycombine () is an inbuilt function in PHP which is used to combine two arrays and create a new array by using one array for keys and another array for values. In this case, array_merge_recursive will yield the same result as the first example: it takes the value from the $second array, and appends it to the value in the $first array, which already was an array itself. While that looks strange in this simple example, it's actually more useful in cases where one of the values already is an array, and you want to merge another item in that array, instead of overriding it. Instead over overriding the original key value, array_merge_recursive created an array, with the original and new value both in it. This function adds elements of one array to the end of the previous array and returns a single resulting array.
