<?php
	$array1 = array(1,2,3);
	$array2 = array(10,20,30);
	
	/* Merge two array */
	$merge1 = array_merge($array1,$array2);
	
	$array3 = array(1 => 'PHP', 2 => 'Java', 3 => 'C++');
	$array4 = array(10 => 'C', 11 => 'Python', 12 => 'JSP');
	
	/* Merge two associative array */
	$merge2 = array_merge($array3, $array4);	
	
	var_dump($merge1);
	echo '<br />';
	var_dump($merge2);
	
	/* Merge associative array with '+' operator */
	echo '<br />'.var_export($array3 + $array4, TRUE);
?>



/* Output */
