add successor in key array php code example

Example 1: php append to array

$myArr = [1, 2, 3, 4];

array_push($myArr, 5, 8);
print_r($myArr); // [1, 2, 3, 4, 5, 8]

$myArr[] = -1;
print_r($myArr); // [1, 2, 3, 4, 5, 8, -1]

Example 2: php add to array

$fruits = ["apple", "banana"];
// array_push() function inserts one or more elements to the end of an array
array_push($fruits, "orange");

// If you use array_push() to add one element to the array, it's better to use
// $fruits[] = because in that way there is no overhead of calling a function.
$fruits[] = "orange";

// output: Array ( [0] => apple [1] => banana [2] => orange )

Example 3: add item to array in php

<?php

$a=array("red","green");

array_push($a,"blue","yellow");

print_r($a);
?>
