Given two array arr1 and arr2 and the task is to append one array to another array.
Examples:
php
Output:
php
Output:
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 = array("Geeks", "g4g");
$arr2 = array("GeeksforGeeks", "Computer science portal");
// Get the merged array in the first array itself.
$arr1 = array_merge($arr1, $arr2);
echo "arr1 Contents:";
// Use for each loop to print all the array elements.
foreach ($arr1 as $value) {
echo $value . "\n";
}
?>
arr1 Contents: Geeks g4g GeeksforGeeks Computer science portalUsing array_push Method: This method pushes the second array element in the first array in-place. Example:
<?php
$arr1 = array(1, 2);
$arr2 = array(3, 4);
// arr2 elements are being pushed in the arr1.
array_push($arr1 , ...$arr2);
echo "arr1 = ";
// Use for each loop to print all the array elements.
foreach ($arr1 as $value) {
echo $value . ' ';
}
?>
arr1 = 1 2 3 4Note: Another way to do it is by ' + ' but it gives fatal warning in the newer versions, hence it is not recommended.
