PHP append one array to another (original) (raw)

Last Updated : 03 Nov, 2018

Given two array arr1 and arr2 and the task is to append one array to another array. Examples:

Input : arr1 = [ 1, 2 ] arr2 = [ 3, 4 ]

Output : arr1 = [ 1, 2, 3, 4 ]

Input : arr1 = [ "Geeks", "g4g" ] arr2 = [ "GeeksforGeeks" ]

Output : arr1 = [ "Geeks", "g4g", "GeeksforGeeks" ]

Using array_merge function: This function returns a new array after merging the two arrays.Example:

php `

arr1=arraymerge(arr1 = array_merge(arr1=arraym​erge(arr1, $arr2); echo "arr1 Contents:"; // Use for each loop to print all the array elements. foreach ($arr1 as $value) { echo $value . "\n"; } ?>

`

Output:

arr1 Contents: Geeks g4g GeeksforGeeks Computer science portal

Using array_push Method: This method pushes the second array element in the first array in-place.Example:

php `

`

Output:

arr1 = 1 2 3 4

Note: Another way to do it is by ' + ' but it gives fatal warning in the newer versions, hence it is not recommended.
