Concatenating Arrays in PHP involves combining the elements of two or more arrays into a single array. This operation is useful when you need to merge multiple arrays to create a larger array containing all their elements.
Using array_merge()
Function
array_merge( )
in PHP combines two or more arrays into a single array, preserving numeric keys and reindexing if keys are not numeric, effectively merging array elements.
Syntax
$result = array_merge($array1, $array2);
Example: Implementation to concatenate arrays.
PHP
<?php $array1 = [1, 2, 3];
$array2 = [4, 5, 6];
$result = array_merge ( $array1 , $array2 );
print_r( $result );
?> |
Output
Array ( [0] => 1 [1] => 2 [2] => 3 [3] => 4 [4] => 5 [5] => 6 )
