==array_merge() example==



<source lang="html4strict">

<?
$array1 = array ("color" => "red", 2, 4);
$array2 = array ("a", "b", "color" => "green", "shape" => "trapezoid");

==array_merge( ) function combines two or more arrays by renumbering numerical indexes and overwriting string indexes==



<source lang="html4strict">

array array_merge ( array arr1 [, array arr2 [, array ...]] )
<?
$toppings1 = array("Pepperoni", "Cheese", "Anchovies", "Tomatoes");
$toppings2 = array("Ham", "Cheese", "Peppers");
$both_toppings = array_merge($toppings1, $toppings2);

==array_merge() function merges 1 to N arrays together==



<source lang="html4strict">

The function"s syntax is: array array_merge (array array1, array array2, . . ., array arrayN)
<?
$arr_1 = array ("s", "g", "l");
$arr_2 = array ("b", "c", "l");
$arr_3 = array ("p", "o");

$arr_4 = array_merge ($arr_2, $arr_1, $arr_3);
print_r($arr_4);
?>

</source>

==array_merge( ) retains array keys when possible.==



<source lang="html4strict">

<?
$arr1 = array("Paul"=>25, "I"=>38, "Nick"=>27);
$arr2 = array("I"=>27, "Paul"=>38);
print "Merge:\n";

==obtaining the union of two arrays==



<source lang="html4strict">

<?php
function array_display($array, $pre=FALSE) {
$tag = $pre ? "pre" : "p";
printf("<%s>%s</%s>\n", $tag, var_export($array, TRUE), $tag);
}
$arr5 = array(1 => "x", 2 => "y", 3 => "z");
$arr1 = array(1 => "x", 2 => "y", 3 => "z");

array_display(array_merge($arr1, $arr5), TRUE);
array_display($arr1 + $arr5, TRUE);
?>

</source>

==Using array_merge() and the + operator with associative arrays as well==



<source lang="html4strict">

<?php
function array_display($array, $pre=FALSE) {
$tag = $pre ? "pre" : "p";
printf("<%s>%s</%s>\n", $tag, var_export($array, TRUE), $tag);
}
$dogs1 = array("A" => "C", "B" => "C", "D" => "C");
