PHP基础数组取值
数组1 ( [0] => company [1] => online [2] => call [3] => banner [4] => archive )
数组2 ( [0] => company [1] => banner [2] => archive [3] => logo [4] => movie [5] => product )

现有数组1,2，我该如何才能得出
数组3( [0] => online [1] => call )
数组4( [0] => logo [1] => movie [2] => product )

php PHP基础数组取值
------解决方案--------------------

$a1 = array('company', 'online', 'call', 'banner', 'archive'); 
$a2 = array('company', 'banner', 'archive', 'logo', 'movie', 'product');

print_r(array_diff($a1, $a2));
print_r(array_diff($a2, $a1));

Array
(
[1] => online
[2] => call
)
Array
(
[3] => logo
[4] => movie
[5] => product
)

------解决方案--------------------


	$ar1 = array('company', 'online', 'call', 'banner', 'archive'); 
	$ar2 = array('company', 'banner', 'archive', 'logo', 'movie', 'product');
	$ar3=array_slice($ar1,1,2);
	$ar4=array_slice($ar2, 3);
	print_r($ar3);
	print_r($ar4);

楼上两位的结果相同，但想法完全不同
#1求差集
#2求片段
LZ没说清目的，所以选用的时候要搞清你的需求……
