利用array_merge()函数将php中的数组整合

array_merge    ( array $a ,array $b,......  )

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

输出：Array
([color] => green[0] => 2[1] => 4[2] => a[3] => b[shape] => trapezoid [4] => 4)

<?php
$array1 = array(0 => &#39;zero_a&#39;, 2 => &#39;two_a&#39;, 3 => &#39;three_a&#39;);
$array2 = array(1 => &#39;one_b&#39;, 3 => &#39;three_b&#39;, 4 => &#39;four_b&#39;);
$result = $array1 + $array2;
var_dump($result);
?>

输出：
array(5) { [0]=> string(6) "zero_a" [2]=> string(5) "two_a" [3]=> string(7) "three_a" [1]=> string(5) "one_b" [4]=> string(6) "four_b" }

<?php
$beginning = &#39;foo&#39;;
$end = array(1 => &#39;bar&#39;);
$result = array_merge((array)$beginning, (array)$end);
print_r($result);
?>

输出：Array ( [0] => foo [1] => bar )
